Along with this reduced overall speed, we gain efficiency because the motor is not trying to go to higher speeds, so it tops out. “On the new motors, the top speed of the windings is 25-32km/h, so your torque curve is more condensed, and we are able to supply torque at lower speeds. The motor has to supply power across that range, whether your bike is limited to 25km/h or not. Basically, the top speed of the windings can go to ~42km/h. “The previous RadRunner motor has a higher top speed focus/range. It's not possible to reduce this to a simple fixed number. … The way we've designed our new motors changes the way the torque is generated. When I asked how much torque the motor produced Rad told me: “We don't attribute a specific number, due to being reductive.
