Hello Jim,

The motors will run off any dc voltage but they are rated for over 100 volts. Off my 18V drill battery they have some torque but don't spin very fast. I don't know if they would push a bike unless you used a higher voltage. Worth bench testing.

The motor controllers are switch mode power supplies that are designed to run off 110ac. Wouldn't work off low voltage DC without significant modifications. Would be easier to scrap them for parts and build a low voltage PWM motor controller. Just a guess.

i am interested in the dc motors so i could convert my bike to a e
bike do you have the speed controllers as well for them

and welcome to the insanity of The LAB heheh

Many of them are brand new. I may be able to get some for free. The drive motors are dc, 1.5-3 HP. The linear actuators are slow but high torque gearbox ac motors with wormwheel shafts on them.
