I'm set to add an electric motor to my old Trek road bike, because...well, because I can, I suppose. I thought I'd start a blog thread about the build and the results. Also, to see if any other nutjobs out there have experience they'd care to share.
What I've got:
2. DC motor (1300W, 90V, 3000RPM) from a garbage-picked treadmill (motor works; electronic treadmill controls don't).
3. 12V Pb/H2SO4 battery
4. 12VDC-to-115VAC inverter.
What I plan to do:
Step 1: feasibility test--attach a ratcheting sprocket (from a dead child's bicycle) to the drive shaft of motor. Link motor to front chainring of bicycle. Then...as a "proof of concept" test, run the battery, through the inverter (and a bridge rectifier that I'll bet is somewhere on the treadmill carcass) and to the motor...and the wheels.
Once I can demonstrate this actually produces motive force, I can worry about trivialities (such as a throttle). Also worry about acquiring a power pack a bit more efficient than what I've described.
I'll continue to update this thread as this lunacy progresses...
