This was a pet project of one of the guys at Zero Motorcycles, but boy does it look like fun. Using the electric motor they are able to create nearly 3x the horsepower and EIGHT TIMES the torque. This thing produces more torque than my FZ07 that weighs 400 pounds. I think they should sell this one as a unicycle instead of a motorcycle as the front wheel will never be on the ground.
Would you ride an electric Grom as a commuter?
Check out the size of that rear sprocket!
