72V3000W Hub Motor Kit for Electric Bicycle 20x4.0 inch Rear Drive Fat Bike 175 Dropout with TFT Color Display Conversion Kit

Exceeded expectations except for one thing and that is the headlight instruction. I had to build a separate battery and run my headlights separately from the whole system. Other than a page missing, I was actually impressed with the manual too, not perfect but way more than anyone else gives and has some extra detailed info you would have to look up online with other kits. Quality kit and with a 100lbs ebike plus my 200lbs throws me up and down my street at 50mph and gains acceleration quickly.. Tons of torque so don't forget to install torque arms four plates or a DIY custom solution like I had to do. You will regret not doing this but if you do it can be a cruising, commuter, or racing jobs and it's functional no matter how you use it.
