Lighting A New Way Forward?

 How would you like a lamp that gives off as much light as five 100-watt bulbs but weighs less than two?

Yes, for your bike.

Well, BYB Tech is promising with their Focus One light.  What's more, the Italian start-up says you'll be able to regulate the amount of light and how often it flashes from a small button on the device, or from a remote handlebar control.





Those aren't the only promises or claims BYB Tech is making.  While they don't claim to be the lightest bike light of all, they say that the Focus One is the "world's smallest 5000 lumens light" and that it will allow cyclists to be "seen like a car."




Of course, like almost any new technology, it isn't cheap to buy--or produce.  To address the latter, BYB Tech has opened a Kickstarter campaign that will help them, well, kickstart production. If you want to buy one now, making a donation to the campaign will reduce your price for a unit.

Lighting--And Measuring--The Way

Soubitez and Huret.

What do they have in common?  Well, for one thing, they're both French.  For another, they made parts and accessories found on constructeur bikes as well as basic ten-speeds from the 1970s Bike Boom.

Huret was best-known for its derailleurs, though it made other parts.  Soubitez, on the other hand, was renowned for its bicycle lights, most of which were dynamo-powered.

So, other than being French and found on many of the same bikes, Soubitez and Huret wouldn't seem to have much in common--or much reason to collaborate.  Or would they?

In addition to derailleurs, shifters and frame fittings (such as dropouts), Huret also made some cycling accessories.  Perhaps its most famous was its Multito cyclometer, which ran quieter and registered more accurately than other bicycle odometers because it used belt-driven pulleys rather than the wheel-and-striker system of more traditional devices like the Lucas. 

Before the Multito was introduced, in the late 1970s, Huret made speedometer/odometers that attached to the handlebars and emulated similar devices found on motorcycles and in cars.  Huret sold it under its own marque, but bike makers like Schwinn rebranded it, which is how it ended up on countless kids' "muscle" bikes of that time.

Schwinn and other companies also rebadged Soubitez lights and dynamos, including the extremely popular "bloc" dynamo-light combo that attached to the front fork. (I had one on my Continental.) 

Even with the seeming ubiquity of Soubitez lights and Huret speedometers and odometers, I don't think it ever occurred to me (or anyone I knew) to combine a light with a speedometer or odometer.  Apparently, though, it was done.  





I tried to find more information about the Soubitez 941 K N.  It may well have been exported to the US and I missed it, but I don't recall seeing it anywhere back when so many of us rode with Soubitez blocs and Huret speedometers (and derailleurs:  the one on my Continental was a re-branded Huret Allvit).  The 941 K N seems to have been supplied with a Huret speedometer cable and driver.  They may well have been the power source for the light.  Or, judging by the shape of the light, it may have housed dry-cell batteries.

If that driver and cable were indeed the light's power source, it's not hard to imagine that the Soubitez 941  K N may well have influenced modern bike computers. Otherwise, it's an interesting curiosity.

A Mission To Be Seen

Bicycles with integrated lighting systems are usually associated with touring bikes and randonneuses from the constructeurs and, to a lesser degree, high-end builders in other countries.  A few production bikes have been supplied with generators built into a bike, or more commonly, a hub, and lights built onto racks and fenders, if not the frame itself.  

Such bikes usually have wires routed into the fenders or racks so they are not only not visible, but not vulnerable to being snagged and snapped.  A few bikes have wiring built into the frame itself.


While it's nice to have lights built into a bike that's frequently ridden in the dark, they are vulnerable to theft if the bike is frequently parked on the street, particularly in the same spot.  Also, light technology has improved dramatically (though, I admit, I prefer the styling of old lights) and a built-in system might tie its rider to an inferior technology.

The latest technology in bike lights, and lighting generally, is Light Emitting Diodes (LED).  This makes smaller, sleeker and lighter (in weight as well as luminosity) units that can fit more easily on different parts of the bike.  They are as much an advance as halogen lights were when they appeared about 35 years ago and displaced the incandescent bulbs that had been in use almost since their invention. (A few lights were made with fluorescent bulbs, but the idea never caught on because they're not good at throwing a beam forward, even through a lens with the best of optics.)



Apparently, someone out in San Francisco wanted a built-in lighting system with the advantages of LEDs.  The result is that Misssion Bicycles, a local company, has just introduced a bike with LEDs built into the inside each fork blade and on the rear of the seatpost.  They are powered by a rechargable battery inside the headset that can be turned on by a cap on the stem.  Thus, the bike shares one characteristic of those custom bikes with integral lights:  wires that run through the frame.



Such a system, to me, makes sense on a bike used for commuting in an urban area.  The lights wouldn't do much to help a rider see the roadway ahead, but they will help him or her be seen in traffic--which I know, from experience, is far more useful for night riding on city streets.  And they would be more difficult to steal than other kinds of lights when the bike is parked.  The one downside I can see is that if the lights need to be replaced and a new technology displaces LEDs.
