Casey Anderson, Global Training Manager at BionX, shows off the new BionX D Series electric bike system, the new 48V BionX battery, center mount console, new cassette freehub BionX motor, and Dahon folding bike with the new BionX L Class e-bike kit.
I love the video and like the BionX product. I test drove a bike with the BionX kit and was very impressed with it. In this video the torque of the new D series motor is talked about and I have a question about it. How can the motor go from a nominal 20 newton meters to 50 newton meters? Does this mean that the torque of the motor is constantly changing and what is causing it to change? Also, is the peak torque only for a few seconds or is it longer like 20 or 30 seconds so you can climb a steep hill easier? Maybe you could clarify something that is mentioned a lot but never explained.
