How Does A Bike Light Work

The basic concept behind a battery free bicycle light is to use the motion of the bicycle wheel to generate electricity.

How does a bike light work. In addition the hostile environment we expect our lights to operate. A secondary purpose is to illuminate reflective materials such as cat s eyes and traffic signs a third purpose may be to illuminate the roadway so that the rider can. The top of the dynamo touches the tire s rim which spins when the bicycle starts moving. Like a car wheel a bicycle wheel is a speed multiplier.

In general i would recommend protected cells they cost a tiny bit more but it s worth the extra peace of mind in my opinion. The autumn and winter period in the uk is never the easiest time for bicycle commuters who invariably have to contend with colder temperatures increased rain and longer hours of darkness. Supernova ebike light available with different mounting options for handlebars and forks most work with 6 volts but they have some that will work with 12 60 volts if your system doesn t have a low voltage output and you want to connect directly to your battery. The faster the wheel moves the more power is generated.

It is however perfect for urban riding with a bright 500 lumens light with several brightness settings and a flashing mode. The pedals and gears turn the axle at the center.
