FAILED EXPERIMENT in September 2008:

A weak motor from an electric scooter is not powerful enough to drive a cheap and heavy mountain bike. Bike could barely maintain speed. Might have been different with better gearing.

30lbs of Lead Acid Batteries were carried in a BACK PACK on my back - Don't do this. It was a real pain in the shoulders.

Complete drive system was Recycled to use at Earth Day Fair to demonstrate the simplicity of the electric drive system.
