I have a Crystalite rear hub motor from Electric Rider that I really like, I just don't use it much so it's up for sale if you have a reason to come up to west central Wisconsin any time over the winter, right now it's a full bike, with a 36v controller (some people say you can run the motors up to 96v but they were designed as a 72v motor), I also have a 36v 10ah
Ping battery and am willing to sell the whole set up for $600 or just the motor/wheel, with speed controller, throttle for $500, no battery and no bike frame.
When I was running that bike with 33v dewal batteries it would go 27mph without pedaling and I'm 250lb so at a true 36v and with someone smaller on it it's going to go faster! that is why I bought that motor, I liked the idea of being able to go faster!
If I don't sell it, I plan to build a cafe racer Ebike using a Chinese scooter's title and vin so I don't have to have pedals on it.
