"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 hope he has a lot of cordless drills laying around. I think he's going to be going through a few.

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.

Starters are meant to be run for a few seconds at a time, not continually for minutes (let alone hours) on end. In grade school, I was part of a project that attempted to use a starter motor to move a small wooden go-cart kind of thing. We melted 5 starters within 3 days of building.

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.
