I have 3 Electric bicycle wheel kits. They are brand new. 36V system so they are the more powerful ones. These are brand new, and typically cost 400-500 dollars elsewhere. They come complete even with battery. They include Charger, Twist throttle, Regulator, Rack, Tire, Rim, motor hub, levers with switches, when you coast and brake the motor becomes a generator and charges up the battery for extended range. These are expensive kits. It is a front wheel kit. Just swap in the front wheel with this wheel and the hub is a brushless DC motor. Sweet. I only have 3 at this price. Contact me if you want one. Thanks..and..Enjoy the ride..
