Electric Bicycle Kit, 72V 2000W E-Bike Rear Wheel Hub Motor with Mutifunction LCD Display & Pedal Assistant Sensor, 60N.M 7-Speed Flywheel E-Bike Conversion Set US Stock

Excellent 40 mph on 48v not sure on 72v

The kit was complete simple easy to understand performance is very very well I would recommend it with anybody who has steep inclines or prefers to ride on the mountains

Worked perfectly for my Schwinn Xumm 29" rim, I've hit 50 uphill and live it! Doesn't come with a battery which is another $350, but my bike is a beast now!!

item came in timely manner and was fairly easy to install as I have done it before and have had to remove and install many times since i have had a few flat tires. electronics are fine only problem I have found when plugging battery in there is a spark that happens at connection so you have to keep changing plugs

Since I live in a hilly area, I can't pedal for long on some very steep hills uphill and need an auxiliary motor to help me up, this conversion kit is a good quality install with just enough power for my daily commute and safety.

I just love it.... Absolute boss. this is a short period review. maybe 2weeks or so. Nothing else to say. Technical details: I reached max 40mph speed. I think I could go more, but don't wanna cause accident. The road was straight, not uphill or downhill. My battery is 72v 20ah Heads up, you might need a torque arm to hold this thing and not rip the frame off! Also I made my own regen braking which tripled my braking force. It's brake produced from the motor, you can see the last image. So torque arm was a must for me other wise the bolts were coming loose time to time
