This is an updated version of my original Bike Generator. The first version served its purpose but was fairly limited. BikeGen, is better in almost every way and here are some of the reasons why:
1. The generator motor is now mounted with more rigidity to the rack instead of the frame.
2. The friction drive wheel is mounted to the motor with a clamping coupler and now runs on the braking surface of the wheel and not directly on the tire.
3. BikeGen recharges two AA batteries instead of powering the headlight directly, so the lights stay on even while your stopped.
4. Two AA batteries are used to power both the head light and the tail light, which means I don't have to bother buying AAA batteries for the tail light.
NOTE:Please read my Bike Generator Instructable and follow the steps about building the the circuit board before attempting to build BikeGen.
