DIY Electric Bike Conversion kit 250W Brushless Motor and Controller,Electric Bike Booster kit Waterproof Ebike Conversion Kit Friction Drive Bicycle Kit

This garbage chunk didn't work for two seconds. The controller comes disassembled, and they expect you to clip wires and rewire the controller. The instructions are on a video that is entirely in Chinese where you can see nothing. I hate Amazon for putting this fraudulent chunk of sewage up for sale. I have asthma and a heart murmur and dreamed of having help biking, but this horrible toilet of a product did not work at all.

runs great

Ok, but somewhat under powered, otherwise ok. Serves the purpose.

Worthless product and worthless support! I installed it on two different bikes with at 36 volt battery with the same result--no boost whatsoever. Tires are fine, no slippage when running, just no power whatsoever at any speed. I messaged for support and requested to return it complete with photos, but I was told I was too late to return (a week too late).

Was easy to hook up put it on my bike and it works haven’t ridden it yet but seems ok will start using it when winter is gone have new battery too

Drivewheel did not last very long at all.

My son is using the items. He said they are working fine.

I recieved everithing fine thank you verymuch Diego

I really like the unit....It is a little bit of work ...but it does work quite well....

Solid build and it definitely gives you the boost you need for up hills however the installation process was vexing as I had to retrofit a metal adjustment band to keep the motor affixed firmly. Buyers beware of this or you'll go through the same frustration I did..
