I bought a 36V 350W scooter from Craigslist today for $25. With all the rust and decaying parts, I don't think I want to use it as a scooter. I'd prefer to ride an electric bike too.
So, I'm wondering what's the best way to mount the motor and add a sprocket to the rear wheel of my bike. I've seen examples, but I'm wondering if I can do it with just the motor and a large sprocket. I know a hub motor is the simplest way to go, but I've already got working batteries, a controller and motor. It'll be a shame not to put them to good use.
