Works great on my 26" wheel commuter bike. It is a single speed with the standard 46T and a 22T on the rear. It easily maintains 30kmh on my trip to and from work.

I ordered a Bafang 500W mid-drive to install on my 21 speed mountain bike. I was happy with the 4 day delivery from Ontario to Alberta. Installation was very easy. After quick spin around the neighbourhood, I was impressed with it's performance going up hills and riding into the wind. My bike goes faster now than it ever has.

This motor does all I have asked it to do . That said I do not ask it to go up hills really fast in high gears on very hot days ; for sure it can overheat and performs best for with lots of downshifting for fast cadences... Riding to work this week there was flash flooding and the Bafang powered me through about 25 meters of water . My feet were under the the water for half of each pedal turn...had to keep going , this was a subway construction zone, vehicles behind and fences on the side . I was amazed that the motor kept going not only thru the river that appeared on what is usually Eglinton W , but also afterwards... it has also exceeded my expectations so five stars and hats off to Bafang ....

Pretty good kit but perhaps needs programming before sending out. Installed on my tricycle - David S - Sep 05, 2019
