B&M Lumotec IQ Cyo senso plus T

The Cyo T is much like the 60 lux Cyo, but with a row of four LEDs under the main lens which direct light at oncoming traffic for enhanced visibility

I have replaced my ailing B&M Lyt plus with the catchily-named Lumotec IQ Cyo senseo plus T also made by B&M. There are currently around ten+ variants of the Cyo, including 40 and 60 lux versions (the 40 lux incorporates a reflector which the 60 does not) bottle or hub dynamo versions, near-field lighting versions, automatic on/off via light sensor versions, versions with daylight running lights and either a black or silver finish for some of these models (as discussed previously). 

The Lumotec IQ Cyo senseo plus T is the hub dynamo version of the 60 lux Cyo, with automatic on/off via light sensor and daylight running lights. In this version, the light sensor switches the light between day and night modes. The daylight running lights consist of four LEDs underneath the lens for the main beam. Unlike the main beam which is directed at the road, these LEDs are directed at oncoming traffic as an aid to 'being seen.' During the day the main light beam is at significantly reduced intensity, whilst the four LEDs underneath the lens are all illuminated. At night, the main beam is illuminated to full intensity and only two of the daylight running light LEDs are illuminated, with these two LEDs also forming the stand-light feature in this model.

Whilst I am very happy with the Philips Saferide lamp recently acquired for the DL-1, the unique proportions of the Brompton mean that only a handful of front lights can be fitted without causing problems with the front luggage system. The Saferide is not one of these due to the lack of mount compatibility with B&M fixings (unless modified). Brompton specify either the bottom-of-the-line Lumotec halogen light with the Shimano dynamo wheel or the top-of-the-range (ish) 40 lux Cyo with the SON dynamo wheel. This is perhaps a little unfair to customers, as it suggests that the Shimano dynamo wheel can only power a low end light, despite it being capable of powering the same range of lights as the  SON*. As I discovered, as an alternative option the Lyt can be fitted to a Brompton by using a Cyo mount, although my initial research suggested that this was not common.

In complete darkness the Cyo T provides almost as much illumination as the Saferide. The beam is a bit less wide and the throw seems a little less too. The apparent subjective reduction in throw compared to the Saferide is likely a result of the central bright spot which comprises part of the beam shape. Whilst useful for avoiding potholes (especially so on a small-wheeled bike), the bright spot does make the rest of the beam which is projected beyond it seem less intense than it actually is. The slightly reduced beam width and throw compared to the Saferide is likely being exaggerated in this case by the lower mounting height of the Cyo on the Brompton (~350 mm) than on a conventional bike (~750 mm), but the beam is still entirely sufficient.

Where the Cyo T excels is in its urban-friendly features, such as daylight running mode which to helps mitigate the risk of not being seen by negligent motorists, and the automatic switching between day & night modes via light sensor. The daylight running lights are particularly effective at drawing extra attention in daylight, directing a good amount of light at oncoming traffic. At night, the two lower LEDs which remain turned on are illuminated to a lower intensity, to avoid blinding oncoming traffic. The automatic light sensor can be over-ridden if desired to keep the Cyo T in daylight mode at night. The level of road illumination provided by the light in 'day mode' is sufficient in well-lit areas where being seen may be of more concern than lighting up the road itself, still meeting the minimum standard for a 'proper' light.

The stand-light is different to other lamps I have used. Like the Lumotec Retro, the stand-light is provided by auxiliary LEDs rather than using the main beam as the Saferide and Lyt do. However, unlike any of these other lights the stand-light does not merely stay illuminated until the capacitor has been discharged, it is timed to shut off after around four minutes despite the capacitor having a capacity for a greater length of time. The result of this is that the stand-light is immediately available if the bike (dynamo) is moved again.

The rotary switch on the rear of the Cyo has three settings, off, sensor and daylight mode

Unlike the 40 lux version of the Cyo and the Lyt, the Cyo T does not come with an integrated reflector. A reflector is available for adding to the bottom of the standard Cyo mount, although the Brompton mount is not compatible with this. It is also worth noting that the Torx bolt which comes with the standard Cyo mounting bracket is not compatible with the Brompton Cyo mount due to the different tube thickness. Whilst this set-up has left the Brompton without a front reflector, the daylight running lights are definitely a replacement which is in the spirit of the law even if it does not conform to the letter of it.

The Torx bolt has instead been pressed into service mounting the Lyt back on the Yuba Mundo

I like the Cyo T. In plain terms of brightness and throw, it is not as good as the Saferide, but as I stated in that review, for urban utility riding the beam of the Saferide is overkill. The Cyo T also provides more than enough light for riding along unlit roads. However, the daylight running mode and the automatic switching between day and night modes make this an ideal choice for the primarily urban cyclist, whilst the beam it provides is more than sufficient for riding on unlit roads and paths too. Unless you do a great deal of your riding on completely unlit roads, these extra features probably make the Cyo T the better choice.

*The Brompton SON dynamo wheel could be used to drive a pair of front lights as is fairly common practice amongst SON owners. For typical Brompton usage it is probably not worth the extra cash.

Philips Saferide dynamo lamp

I briefly mentioned this lamp at the end of the recent post about dynamo lighting, having read universal praise of it online. I continued to look for more information on the lamp and I found an online shop selling it at a price which seemed too good to pass up. Wanting to find out more, I bit the bullet and ordered the lamp.

After a few days, the lamp arrived. The Philips Saferide has a rated light output of 60 lux, the same as the B&M Cyo (although this number alone actually tells us very little). Also like the Cyo, the housing is aluminium to facilitate LED cooling (however, only a portion of the Cyo housing is aluminium). Like most dynamo lights, the beam is dipped so that the majority of the light ends up illuminating the road rather than blinding oncoming traffic.

I was most intrigued by this; it appears that in some jurisdictions this lamp is sufficiently bright for use on 50 cc motorcycles too.

The light comes with a bracket and integrated reflector. The reflector also houses the wire after it leaves the lamp, which would have to be dismantled ion order to change the bracket. At the lamp end. whilst similar to the B&M mounting the Saferide mount is wider at this point, use of B&M mountings would require some bracket modification in order to work. 

The light source of this lamp is indirect; the beam is formed by a pair of LEDs which sit at the top of the lamp. The optics then direct the light provided by these LEDs into an even beam.

The cables leaving the back of the lamp include a pair for connecting to the dynamo and a second pair which terminate in spade connectors, for hooking-up a rear light.

The only criticism I have seen of this lamp is that the bracket is weak at the fork crown end, due to the scoring pictured above. In order to mitigate this, I used large washers when the light was mounted in order to spread the load over a wider area of the bracket.

The Saferide on the DL-1 (which I should clean). Whilst the Brompton is more in need of a new front lamp, the bracket of the Saferide would not be compatible with the luggage block. The Saferide is less aesthetically appropriate than the Lumotec Retro which was previously fitted to the DL-1, but the DL-1 is a working bike, not a museum piece.

Unlike the Lumotec Retro, the Saferide does not have the automatic on/off via light sensor feature which I came to appreciate. The Saferide is controlled by an on/off switch on the top of the unit, which also turns off the stand-light when switched off. The capacitor holds the charge for at least a day even when switched off, so the stand-light can be turned back on when unlocking the bike.

Now, onto the performance of the light itself. This thing is bright, I mean seriously bright. The first ride I did with it was Halloween Critical Mass, which took place as it was starting to get dark. By the end of the ride it was completely dark and the mass was heading to Platt Fields park (which lacks lighting in many parts). By this point I was towards the back and the Saferide was illuminating the lower half of all the bikes in front of me and completely outshining the lights on the 15 or so bikes in front of me. 

The best light I have to compare the Saferide to is the Lumotec Lyt. The Lyt provides enough light to ride quite comfortably on unlit country roads, producing a bright, slightly narrow beam with a halo of light thrown wide to provide visibility of the sides of the road, overhanging vegetation, visibility for oncoming traffic and illuminate road signs. In comparison, the Saferide has a taller, notably brighter beam which is about twice the width. The whole width of a country road is illuminated easily, and the beam stretches up to around 50 metres in front of the bike. The 'halo' of the Lyt is replaced by a slightly odd 'broken halo,' similar to the stylised rays surrounding a child's drawing of the sun. These 'rays' provide visibility of the sides of the road nearer to the bike and do an excellent job of lighting up road signs and the reflectors on parked cars. When I took the DL-1 on a ride along some unlit country roads in the dark using the Saferide, after a while I wasn't sure how dark it had been when I set off. Switching the Saferide off for a moment confirmed that it was indeed completely dark at the time.

I would like to compare the Saferide to similarly-rated lights such as the Edelux and the Cyo. If Mr MiddleAgeCyclist would like to go for a spin somewhere at night, I'd be happy to see how the Saferide and Edelux compare.

For urban utility riding, the Saferide is complete and total overkill. For rural utility riding, the Saferide represents a worthwhile purchase, especially considering the battery requirements (and conical beam-shape) of a typical similarly bright battery light. Thanks to good (dynamo) lighting, I enjoy riding at night, both for utility and just for fun. For the most part of my riding the Saferide will be overkill, but it will come into its own when I'm riding for fun.

The Lumotec Retro is currently for sale on eBay, although I'd be willing to sell privately to a local instead.

UPDATE (6/11/11)

Yesterday I was able to meet up with Mr Middle Age Cyclist for a ride down the Floop after dark, to compare the Saferide with his Schmidt Edelux. The Floop is completely unlit, providing a good proving ground for the lights. Whilst the comparison is highly subjective, we both agreed that the lights are effectively equivalent in performance. The Edelux casts a slightly taller, more narrow beam whilst the Saferide casts a slightly shorter, more wide beam. The Edelux is effectively a super version of the B&M Cyo, possessing the same optics and LED, but housed in a more thermally-efficient aluminium housing with a glass lens. This set-up is designed to get that little bit more output from the same core light, suggesting that the Saferide is likely an equal, or perhaps marginally superior light to the Cyo. One day I will do another direct comparison with a Cyo. 

Light is Running Out

It's that time of year again. When Sunday comes it will be dark a lot of the time for anyone who works a conventional 9-5 shift pattern. This will be my second winter of riding with dynamo lights, with dynamos on all of the bikes this time, although still only enough lights for two of them; the Brompton and the DL-1. This is the perfect time of year to 'go dynamo,' not only for the long-term savings but, as I learned myself last winter, it's extremely liberating.

Some people hang up their bikes for winter. If you are a utility cyclist however, this is unlikely to be the case. I have ridden through every winter since I started cycling again as an adult. However, until last year I never really got any enjoyment doing it.  Having to remember to take my lights everywhere, carry them around when off the bike was a minor hassle. What really bothered me was the persistent, nagging concern that I'd be caught out by flat batteries and have to risk a ride home without lights. The battery lights I had used in the past were adequate, but never truly that bright. I knew of the much brighter options available but the price never seemed justifiable to me, for something which could so easily become useless if forgotten of accidentally uncharged.

When I bought my first dynamo lamp, a B&M Lumotec Retro N senseo plus, it was mainly because I was concerned with having a light which was in-keeping with the aesthetics of my then new-to-me DL-1. English-language information regarding dynamo lights was pretty sketchy, I wasn't sure what I was going to get. Because of this, I was pleasantly surprised to find that the light I had purchased was actually a lot brighter than my previous battery-powered LED lights, despite being a halogen bulb. It was always there when I needed it and would even come on automatically when darkness fell. This started to change the way I felt about riding in the dark, from something to be avoided to something to relish. As that first dynamo winter drew in, I found myself riding as much as I had during summer. 

Naturally, I had to get the rear light powered by the dynamo too, whilst permanently attached to the bike, the rear the battery light which came with the DL-1 was still a weak link, dependent on batteries. Once again, information was lacking. B&M produced rear lights with the same automatic light-sensor on/off control as the Retro, although it seemed that this feature was only available with the battery or battery/dynamo hybrid models. Once again I took the plunge and purchased a B&M D-Toplight Plus. The tail-light was wired into the connectors on the front lamp for this purpose; to my surprise the automatic light sensor in the front light also controlled the power supply to the rear light. When it got dark both lights would come on automatically (including when passing through a tunnel). Brilliant.

Having this kind of set-up on the DL-1 made the Yuba Mundo seem almost a hassle to ride. The Shimano dynamo hubs available in my price range were all intended for use with Centerlock disk brakes, rather than the standard 6-bold arrangement used on the Yuba Mundo. The additional cost of a new Centerlock rotor or an IS adaptor pushed the price to more than I could justify spending at the time. A post from Lovely Bicycle! gave me the answer I was looking for, a bottle dynamo. Older bottle dynamos (and modern cheap ones) have contributed to the poor regard with which dynamo systems are viewed here in the UK. However, higher-spec bottles such as the Nordlicht 2000 or the B&M Dymotec seemed to offer a reasonable trade-off between performance and price. I decided to opt for the Basil Nordlicht bottle dynamo in combination with with a B&M Lumotec Lyt plus, a reasonably priced light with a higher light output rating than the Retro. Due to budgetary constraints, an additional rear light would have to wait.

Unlike the Sturmey Archer X-FDD hub dynamo on the DL-1, the Basil Nordlicht took a bit more work to find the optimum fitting. The advantage of the Basil Nordlicht is that the rollers can be changed. Multiple variants are available including a steel roller for running on the tyre, a rubber roller for running on the rim and a larger rubber roller for running on the rim at higher speeds. The larger roller is particularly useful as it allows the dynamo to be 'geared down.' As bottle dynamos are typically designed to produce full power output at relatively low speeds (<10km/h) they can produce too much drag when used by faster cyclists. The larger roller compensates for this by reducing the amount of dynamo revolutions per tyre revolution, and hence the resulting drag. Initially the bottle dynamo was mounted on the fork, unfortunately the pressure it exerted on the rim caused the rotor of the disk brake to rub against the brake pads when it was engaged. Eventually I mounted the dynamo on the seat-stay and adjusted the mounting angle which produced ideal dynamo contact pressure on the rim, enough to prevent slippage but not enough to create noticeable drag.

At present the Basil Nordlicht bottle dynamo is still fitted to the Yuba Mundo, although there are no dynamo lights fitted for it to drive. This is due to my acquisition of a Brompton. After a few weeks with the Brompton, I felt that a bike such as this really needed to be all in-one, including self-sufficient lighting. It was around this time that the annual price increases for Brompton components were being rolled out. The Brompton dynamo wheel RRP was about to increase by about 15% making that then the ideal time to upgrade to the Shimano hub dynamo wheel. I had considered the fitting the Basil Nordlicht bottle to the Brompton, but the relatively good price of the wheel and my uncertainty about clearances for fitting the bottle led me to choose the hub over the bottle.

Rather than splash out on a new front light, my limited budget led me to fit the Lyt from the Yuba Mundo instead. My intention was to replace the front lamp on the Yuba Mundo at a later date, which I have still yet to do. Initially I bent the Lyt mount to fit it into the tight space between the caliper brake and the luggage block, a solution which was far from ideal. I was later able to use a Brompton Cyo mounting bracket to fit the Lyt into the limited space offered by the Brompton. I also added a Brompton rear dynamo light (made by Spanninga) to complete the set-up

The version of the Lyt I had purchased for the Yuba Mundo was the bottle dynamo version; when connected to the hub dynamo on the Brompton, both front and rear lights ran whenever the bike was in motion. Whilst not as optimal as the automatic on/off light sensor of the Retro, this set-up actually works well, due to the extraordinary operational lifespan of LEDs. It now appears that I was a little ahead of the curve in choosing this set-up; B&M's entire 2012 range of dynamo lighting comes with the option for daylight running lights.

My experiences with dynamo lighting have not been universally positive. The standlight functions on both of the lights fitted to the Brompton failed by summer, although they were both relatively easy to fix. However, it is my 'off-label' riding with the Brompton which is more likely the cause of this failure than any deficiency in the lights' designs; Bromptons are not really ideal bikes for fast riding on cobbled paths, the resulting vibrations were obviously a bit too much for the capacitors powering the standlight. Under more typical riding conditions I doubt that this problem would have occurred. For this reason I would still strongly recommend dynamo lighting to anyone, including the models of light which I have had problems with.

A great deal of dynamo lighting technology is designed by (or for) the German market. German regulations stipulate that a bicycle must be sold complete with a dynamo lighting system (except lightweight sports-bikes), including lights which conform to specific regulations for beam shape and light intensity. These regulations are more strict than elsewhere and have effectively become the de facto international standard. The misconceptions about dynamo lighting which persist in the English-speaking world means that we do not constitute a huge proportion of the market for dynamo lighting components, with equipment and information  often difficult to come by. B&M in particular make great equipment but the English-language information about them is lacking. They also suffer from the Windows Vista effect; huge numbers of variants on each light model exist with relatively subtle differences between them and confusing nomenclature. These differences are seldom well explained in product descriptions on the handful of retailers which stock them.

Because of this, to help prospective dynamo light users I have produced a B&M dynamo light nomenclature guide:

Lumotec: The front dynamo light brand name.
Toplight: The rear dynamo light brand name.
Retro, Lyt, IQ Fly, IQ Cyo etc: The model name.
Plus: Includes standlight. The light (or a portion of it) remains illuminated for a few minutes after motion stops.
Senseo: Includes automatic on/off via light sensor.
N: Includes an on/off switch, intended for use with hub dynamos.
B: Basic version, lower light output but still meeting German minimum standard.
R: Taller beam, including near-field illumination of dark patch in front of wheel.
T: Daylight running lights. In addition to the beam aimed at the road, a series of small LEDs direct light at oncoming traffic to increase cyclist visibility. During the day these lights remain lit, whilst the main beam runs at reduced power or is switched off.


B&M are of course not the only manufacturer of dynamo lights, merely the one with which I have most experience. Mr Hembrow gives high praise to the new dynamo front lamp manufactured by Philips; the Saferide (repeated elsewhere). It is my hope to test out a Saferide in the future and share my impressions here. If anyone has any questions about 'going dynamo,' please feel free to leave a comment and I will endeavour to help you if I can.

Make Do & Mend

Way back in early August on a ride back to Manchester at night I was worried the see that the stand-light on my B&M Lumotec Lyt, the front lamp on my Brompton had stopped working. The back stand-light on my Brompton had been non-functional for a while too. I couldn’t really justify the expense of replacing either of these lights, especially after such a short time in service. Thankfully, I have some experience of electronics from sixth form college and  had also done some work with battery-backed full-wave rectification circuits previously. The fact that the stand-light had gone on both lights, but both still worked when the bike was in motion suggested to me that the capacitor used to power the stand-light is connected in parallel with the rectified current from the dynamo and in both cases had become disconnected. The rattle was a bit of a giveaway too. I firstly too a look inside the Lumotec Lyt.

The casing of the Lyt can be gently prized apart with the edge of a screwdriver.

The business part of the Lyt, the circuit board, containing the central LED, with the £1 coin-sized capacitor next to it.

After examining the circuit board, I found the part of it to which the capacitor attached. When assembled, the capacitor sits in this position at the top right of the circuit board which sits vertically in the housing. The relatively heavy capacitor is supported at this angle by two contacts soldered in to the board in a manner which is not really ideal for applications with a lot of bumping and vibration, such as in bicycles (especially on the Brompton).

One of the contacts had broken off with the capacitor, a wire was soldered to this end,

and soldered into the circuit board at the other end.

A contact for the side of the capacitor whose original contact was still attached to the circuit board was fashioned from part of the tab from a drinks can,

and placed in contact with the capacitor using tape. The remaining end of the wire pair was soldered to the contact on the circuit board,

and the whole thing was taped (crudely) to the inside of the housing of the Lyt. Whilst hardly a professional job, the result has held just fine for over two months. The situation with the rear light, a Brompton dynamo light (made by Spanninga) was similar, although the capacitor was positioned more sensibly in this design.

The capacitor as intended to be positioned on the circuit board of the Brompton rear light was re-affixed in a similarly crude manner to the capacitor in the Lyt; using solder and a lot of tape. This repair job has also held up surprisingly well since the beginning of August.

The long-term plan is to retire both of these lights to the Yuba Mundo, which is both used less frequently than the Brompton and which, with larger wheels and more voluminous tyres will likely be less demanding on these damaged lights, and replace the front lamp with a Cyo and a new Brompton rear light which I will pre-emptively reinforce. Until I have the funds for that though, I’ll have to make do & mend.

DL-1: One Year On

It has been around a year since I took delivery of my Raleigh Tourist De Luxe. Of course by, "Took delivery," I mean cycled to Didsbury on the Yuba Mundo to meet the old gentleman from whom I was purchasing this fine steed, and towed it back to home. At first I wasn't sure if it would be for me, having had no opportunity to test ride it. What I did know however, was that if I didn't like it, I could sell the bike (or its component parts) for a fair bit more than I paid for it that day.

When I got the bike home, I adjusted the saddle and took it for a spin. Whilst I liked the ride, it wasn't quite right; the gearing was far, far too high, with first gear being what I imagine a reasonable third gear should feel like on a three speed. The rod-brake handlebar was limited in its range of height adjustment and the angle of the bar was fixed. Luckily, a few replacement parts allowed me to fix these minor gripes and turn the bike into the perfect everyday transport solution for me. Over the past year I have made numerous additions and upgrades to the bike.

Additions and upgrades:

• Rod-brake handlebar, plastic grips and drum-actuating rods replaced with Raleigh North Road handlebar, BBB stitched leather grips, Shimano V-brake levers and Sturmey Archer drum brake cables.
• New larger sprocket to lower the gearing and new Shimano Nexus chain due to increased size of sprocket
• Front-wheel rebuilt with Sturmey Archer X-FDD drum/dynamo hub replacing the original X-FD drum brake hub.
• B&M Lumotec Retro front dynamo-powered headlamp.
• Imitation Raleigh Record-tread roadster tyre replaced with Schwalbe Delta Cruisers in cream.
• Rear B&M D-Toplight Plus dynamo tail-light.
• B&M Lumotec Retro headlamp moved to top of headset via a new bracket.
• Carradice Pendle saddlebag.

I have also been forced to replace a few parts due to failure.

Replacements due to failure:

• New-type Sturmey Archer shifter to replace damaged classic lever.
• New axle and planets for Sturmey Archer X-RD3 rear hub.

However, I should mention that the X-RD3 hub was at least somewhat faulty from the start, and that my own experience shouldn't detract from the consensus that this hub, and internal hub gears in general, are the best choice for a practical, low maintenance utilitarian bike.

After a year riding this bicycle, I can sincerely declare it to be one of the smartest purchases I have ever made. Since getting this bike I certainly cycle a lot more. My odometer is currently displaying a total distance cycled of 13,029 km, up from 8,000 km at about this time last year, most of that distance has been for transportation (as opposed to leisure), covered on the DL-1 because it is such an easy bike to ride.

When I say the DL-1 is easy to ride, I am not just referring to its ride quality (which is excellent). As an upright bike with mudguards, a chain-case, comfortable Brooks saddle and (since the addition of the saddlebag) permanent luggage, puncture-resistant tyres, automatic & permanently affixed dynamo lighting and low maintenance brakes and gears, all I ever have to do if I want to go out is unlock the bike, hop on and go. It is my hope that all of these features represent part of a bigger future for cycling in the UK, even if a lot of them come from its past.

The Tourist De Luxe as it is kitted out today

Whilst not quite the same as my Tourist De Luxe, Raleigh has recently started to sell the Raleigh Superbe again in the UK, after courting the, “Sporting goods,” and “Bicycle-shaped object,” markets almost exclusively here for the past few decades:

The 2011 Raleigh Superbe, is specced and priced similarly to the Pashley Roadster Sovereign (although not made here in the UK). It is available from numerous cycle outlets, including Evans Cycles.

Ten bike parts & accessories due for a comeback

Progress is generally accepted as a good thing, but sometimes new trends, materials and components come along which don’t have all the advantages of the things they replace. This is especially true in the world of bicycles. I present here my top ten bicycle technologies and accessories which I feel are due for a comeback (some of which are already enjoying a bit of a resurgence).

Hub Gears

The innards of a Sturmey Archer AW hub I am currently working on. Even in this state, the hub is still working.

My first experience of hub gears was in Belgium, on a hire bike used for a bicycle tour of Brussels. The bike was equipped with a Nexus 8-speed hub which offered a similar range to my 24-speed derailleur-geared bike of the time. I instantly appreciated being able to shift gear when stationary, the possibilities for enclosing the chain and the increased durability from sealing away the gears inside the hub.

Two of the Three bikes I now own have hub gears.

Drum/Roller/Coaster Brakes

The same bike in Brussels had the most basic model Shimano Roller brakes. These were weaker than the disc brakes I was used to at the time, but once I had gotten used to the reversed brake levers (left-hand front, as is common in countries with right-hand traffic) I came to like the idea of trading a little stopping power over discs for a great deal more durability. Being sealed away in the hub means that their performance is independent of weather conditions, unlike rim brakes. For a bike you depend on to get around, drum brakes are a great option.

The Raleigh DL-1 has similar front and rear Sturmey Archer drum brakes.

Briefcase Clips

Briefcase clips were a common feature of rat-trap pannier racks here in the UK in the days of mass cycling. Naturally in The Netherlands and Denmark they are still relatively commonplace. A small loop protrudes from the side of the rack into which a briefcase handle is placed. The spring-loaded rat trap is then lowered, and a small protruding rod from it holds the briefcase in place.

Whilst briefcases are not as common as they were, I regularly use the clip on the DL-1 for plastic carrier bags when I have been a bit over-zealous with the grocery shopping, or for my U-lock when I have no space in my regular pannier.

Saddlebags

I am hoping to join the saddlebag club soon. Saddlebags were once commonplace, but declined in popularity with the decline in transportation cycling in the UK. Like panniers, they place the load on the bike rather than the rider, reducing the amount of effort required for carrying and preventing the risk of a sweaty back which comes with backpacks. They also offer advantages over panniers; the load is more central and less likely to affect balance and they do not require a rear rack, only a saddle with bag loops such as a Brooks.

Wool

Wool is great. I'm not a big fan of having special clothing just for cycling, I'd rather wear something which is practical both on and off the bike. In the colder months wool is ideal for this, it is warm, it breathes and it absorbs a decent amount of moisture without feeling wet and it doesn't readily hold odours.

Chain Cases

When dérailleur gears are no-longer used, the possibility of completely enclosing the chain is opened up. A chain guard has the advantage of protecting the rider from the chain, meaning no more trouser clips or rolling up your trouser leg. A chain case offers this advantage whilst also protecting the chain from road filth and rain, leading to a longer life and reduced maintenance.

North Road Handlebars

Most of the bikes on sale in the UK come with either riser or straight bars, as seen on mountain bikes, or drops (resembling ram's horns), as seen on racing bikes. These bars offer a moderately aggressive (straight) or aggressive (drops) riding posture suited to sport cycling. For everyday transportation, they are not the best choice for everyone. North road handlebars (and similar variants) offer an upright riding position. The advantages of this include; comfort for the rider, increased head height (ideal when negotiating traffic) and rider weight is shifted back (reducing the possibility of going over the handlebar under heavy braking).

Steel

Aluminium has become a very popular frame material in recent years, due to the pursuit of ever lighter bicycles. It is light and stiff, making it an appropriate material for frames. The different properties of aluminium mean that it is desirable to use oversized tubing, which makes the frame particularly light and stiff. Despite this, many feel that steel produces a better quality of ride, the reduced stiffness of the narrower tubing used in forks seems to allow more of the vibration from the road to be absorbed and dissipated before it reaches the rider. This perception is of course completely subjective, but is something worth considering. Other advantages of steel include the possibility of lugged construction, which I find to be aesthetically pleasing, and the relative ease with which a steel frame can be repaired in comparison to an aluminium one.

Relaxed Geometry

I read somewhere that most of the bikes which have ever been manufactured are of the same basic design as the English Roadster or the Dutch Bike. In the UK however, this design in geometry have fallen out of favour. Whilst the roadster is enjoying a bit of a resurgence due to the popularity various models of Pashley Cycles, the relaxed roadster geometry is mainly only seen on bikes marketed as "traditional" or "heritage" bikes. The geometry of these bikes makes them ideal for everyday transport for the average person's needs. In addition to the models make by Pashley, I'd like to see some more designs based on this geometry available in UK bike shops.

Dynamo Lighting

A topic I have written about extensively, dynamo lights are a great option for an everyday transport bike, where an "always available" lighting solution is very desirable. Most people are put off by memories of cheap bottle dynamos driving terrible filament lamps, but modern hub and bottle dynamos are much better. Combine these with modern LED lighting technologies and you have the perfect dependable lighting solution for an everyday transport bike. No batteries, no fuss.

What bicycle components and accessories which have fallen out of favour would you like to see coming back?

Lumotec Lyt on a Brompton

After my initial attempts at modifying the reflector bracket into a suitable dynamo lamp mount failed, I am pleased to announce that the standard Brompton dynamo lamp wire mount is compatible with the B&M Lumotec Lyt. The arrangement doesn’t interfere with the Brompton luggage system, which was the main concern with this arrangement. This provides Brompton owners to a better alternative to the standard Brompton-branded B&M Lumotec Halogen lamp and a cheaper alternative to the high-end B&M Cyo which is also spec’d by Brompton (when buying the SON hub version of the dynamo wheel).

The space between the Lyt and the bag is actually bigger than it appears in the picture, with a good cm of clearance between the Lyt and the luggage frame.

B&M D-Toplight Plus Review

As I briefly mentioned in the previous post, I have replaced the battery-powered rear light on the DL-1 with a dynamo powered one from Busch & Muller. As seems to be the running theme for good from B&M and dynamo equipment in general, I had to buy it to get any solid information about it. The light is the same one that Ian from Lazy Bicycle Blog ordered for his wimmins’ bike, featuring a stand-light which stays on for several minutes after the bike stops moving.

 

 

The light can be connected to the dynamo or a front lamp using either a single or dual cable approach (depending on the type of dynamo used), terminated with screw(s) or spade connections. If used in conjunction with a B&M front lamp with a light sensor, the rear light will also be controlled by the light sensor/switch at the front. This useful feature is not mentioned in any of the B&M literature I was able to find. I believe that a wire ending in spade connectors can be purchased elsewhere, I was expecting one to be included. When it was not, I decided to destroy an old RCA audio cable and use the screw terminals in the rear light and heat shrink to secure the cable into the front lamp’s terminals instead.

I ran the wire down the inside of the rack frame and along the chain-stay using cable ties.

 

 

 

The connectors on the front lamp have small holes in them through which I threaded the wire. I used heat-shrink to secure them in place.

 

Despite the lack of information B&M provide, the light functions very well. It is sufficiently bright and the stand-light lasts at least 5 minutes, which is all you really need. The ability to use the light sensor of the front lamp is an added bonus which B&M should really make more widely known. I never have to worry about batteries on the DL-1 ever again, and the ability to turn the front and rear lights on or off whilst riding (by overriding the light-sensor) is a small feature which I really appreciate.

Everyday Bicycle

I was initially taken in by the pitch of “Cycling is sport,” that most British cycle shops sell their customers. My first adult bike was a god-awful sub-£100 “Full-suspension” (Y-frame) mountain bike from Halfords. I wanted it so I could avoid spending £35 a month on bus fares getting to my crappy part-time job and for general transportation. Despite the fact that I wanted a bike for transportation, my own perception of cycling as being either mountain bikes or racing bikes combined with the fact that the bike shops generally seemed to only sell mountain bikes and racing bikes meant that I decided to buy a ridiculously inappropriate bike for my needs. Surprisingly, despite its best efforts, I rode the thing for nearly two years. As crappy as that bike was, I learned a lot about the mechanical side of bikes from it (unsurprisingly).

When the spindle inside the bottom bracket snapped I had no idea how to do that kind of repair and I was painfully aware of how low-end my bike was. I was slightly better off by that point and decided to spend a bit more on a new bike. This time, I went to the Edinburgh Bicycle Co-operative and took a look around. What I saw were almost exclusively either mountain bikes, racing bikes or “hybrid bikes.” Once again, with the help of the sport-focussed sales people, I left with a hard-tail mountain bike, a rear rack and a crud-catcher mudguard. I had made a marginally more practical choice; a rack and less suspension, but still an impractical choice for my needs. Despite its limitations, this bike was a revelation about spending a bit more but getting value for money.

I rode this bike for 18 months and slowly made modifications to make it less of a mountain bike and more of a road bike. When I started reading about cycling in other countries (where it isn’t actively supressed by transport policy) and got the Yuba Mundo, I saw the limitations of the mountain bike for practical everyday cycling. By then I was aware of immensely practical bikes such as the Pashley Roadster, but I had just bought a Yuba Mundo and another bike seemed excessive. I started using the Yuba for almost all of my riding; it was much more comfortable, it had proper mudguards to keep me clean and dry and the upright posture made riding much more enjoyable.

Eventually I sold the mountain bike to someone who uses it as it was intended and I bought the Kona Africa Bike. I saw it as a “Yuba Mundo without the Mundo” and enjoyed riding it immensely. Longer trips were uncomfortable, but for the vast majority of my riding it was fine. The hub gears, coaster brake, basket and chain-guard were a revelation, and adding a front drum-brake made it even more practical as a transport bike. I wanted a roadster, but the price was off-putting and having not test-ridden one, I didn’t know what I was missing.

I was lucky enough to find my Raleigh DL-1 on eBay, being sold by a retired Raleigh employee. I was happy enough with the Kona and Yuba, but the price was irresistible. I put in my bid and was very happy to win. The bike had almost all of the utilitarian features I had wanted (or would have wanted had I known of them) since I bought that crappy Halfords mountain bike. Adding the remaining features hasn’t required too much effort:

Roadster geometry:

This was the main draw of the bike for me, the geometry of the English Roadster, now commonly referred to as a Dutch-bike, (because they copied the same design and really made it their own whilst we lost our way, which as an Englishman I find quite sad), is a perfect trade off between the efficiency of the racing bike posture and the basic human desire to be comfortable.

Mudguards:

I cannot oversell mudguards. Once you have ridden with them you won’t go back. Getting rained on isn’t usually fun, but getting filthy water sprayed up from the road by your wheels is much worse. Groundwater is still there after the rain and mudguards will keep you dry. It is insane how few people I see with mudguards in Manchester, where it rains on more than 1/2 of the days of the year.

Rack:

Not really a big ask, obviously needed if you want to carry anything on your bike. It is surprising how few bikes come with racks, and how many bikes I see used as transport but lacking a rack. A backpack will do in a pinch, but is less than ideal. The weight in a backpack moves with your body, wasting more of your energy than if it is on a rack and moving with the bike. Sweaty back is never nice either.

Chaincase:

A chain-guard will keep the oil and crap from your chain off your clothes. A chaincase will keep the water and crap off your chain and keep your clothes clean. Seems fairly logical to me.

Permanent Dynamo Lights:

Quick-release lights are a the norm when using batteries because the lights will work away from the bicycle, making them attractive to thieves. Dynamo lights are less useful to thieves because they require a dynamo. Permanently attached dynamo lights are hard to steal, of low value to thieves, always available and never need fresh batteries or re-charging. The combination of B&M lights I have fitted to my bike use a capacitor circuit (referred to as a standlight) to provide a few minutes of light when stationary, and a light-sensor so that they switch on automatically when it is dark. As a bonus, this feature also works when going through tunnels. The dynamo is conveniently sealed away in the front wheel hub. The dynamo rear light is a new addition, ordered from Dutch Bike Bits.

Internal Hub Gears:

Three gears:

1-Setting off and climbing hills
2-Cruising along
3-Long flats and down-hills

All sealed inside the rear hub. Clean, sealed away from the elements, durable and low-maintenance. One day I might swap it out for a 5-speed hub with a bigger range, for those big up- and down-hill stretches.

Drum Brakes:

Effective, sealed away from the elements, durable and low-maintenance. Drum brakes are long-lasting and unaffected by the weather. I find their lack of popularity slightly odd.

Practical Tyres:

The original tyres which came with the bike were fine, but I decided to replace them with more durable, puncture-resistant and grippy Schwalbe Delta Cruisers. As a nice bonus they are also cream-coloured giving the bike that extra touch of class.

Ding-Dong Bell:

Ping bells don’t produce a particularly loud sound. The ding-dong bell common in the Netherlands and Denmark is both loud and polite-sounding.

A Leather Saddle:

Brooks make the best saddles I have ever used. Whilst they do require a bit of upkeep, they are well worth it. I have enjoyed cycling on mine (after my arse got used to it) and would heartily recommend.

All of these features add up to a bike which is easy to just hop on and go, no special clothing and no need for showering facilities at the other end. It is the ultimate in cheap, fast and enjoyable end-to-end personal transport.
