Today’s invention is a bicycle which requires the rider to undertake some quite athletic non-pedaling movements.
A spring links the rear wheel to the frame as shown.
First, the back wheel’s brake is locked electronically (red) and the rider leans backward, extending the spring (A).
Then, the front wheel is electronically locked and the rider lunges forwards, so that the spring pulls the rear wheel forward (B).
This repeated combination of body movement and electronic control of braking allows forward motion (like an inchworm) to occur.
