"The flexing of the brace also makes an automatic
transmission. As the drill spins faster the chain
jumps to larger chain rings."
I wonder if he built it to flex on purpose knowing it would jump cogs or if it was a surprise and he thought, "Cool, an auto tranny."

I wonder how a car starter motor and a motorcycle 12 volt battery would work? Starters have excellent torque, and the new compact ones using rare-earth magnets and reduction gears are pretty small. It might be a good "hillclimber" motor.

The best electric motor for a bike is still the hub motor. Nothing that I have found matches the performance/size of a hub motor.
