Dynamo-powered rear lights: no more batteries!
A rear dynamo-powered bike light is the perfect complement to a powerful front light. Attaching permanently to the bike - either on the rear mudguard, on the seat stay, seat post or rear rack - you'll never have to worry about replacing batteries or charging your lights again. These lights are available in a variety of shapes, designs and brightnesses. As always, check the specifications before buying to make sure the light is compatible with your bicycle and dynamo system.
