drills? say whattt

wow. its been a long time here. ok so the project is still going and ive found a 25$ drill in which i can basically screw up as much as I like.

ITs got a nice 18v battery and a nice switch from Radioshack which i can use without saudering it to the wires.

Thinking that a normal 18v motor outputs somewhere around 500 ft*lbs. of torque so it should be fine without needing to have a gearbox in between the motor and the, uhh, "drivechain" XD.

In this way i'll be able to drive the chain without needing anything complicated. I only need one gear in relation to the output and with the cheapest single speed bike this should be easy enough. A 0.5:1 ratio should be enough to drive the bike easily. It will undoubtedly need a kick off start but it should be strong enough.
