Review on Voilamart 26" Rear Wheel Electric Bike Conversion Kit, 48V 1500W E-Bike Powerful Hub Motor Kit With Intelligent Controller And PAS System, Restricted To 750W For Road Bike by Jamal Yang

Crazy powerful, and fast. Warning: Do not buy this motor if you are not willing to spend $400 or more on a battery. I love this bike with this motor, but after only a couple miles on a 48v 13AH battery, I have to turn on the limiter, or it will overdraw, and shut down. It needs a 52v 20AH battery or more. It should probably be used on a full suspension bike, because of the added weight. I upgraded the tires to 26 x 2.1, and that helps with tire durability, a problem when overloading a bike.Be sure to turn it off before you get off! I bumped the throttle once wheeling it inside, and it threw itself through the door with the front tire in the air.
