With the ROM-Pedal (also known as the eccentric crank) you get back on the saddle faster!
This solution is developed for people who have limitations in bending (or range of motion) their knee, leg or prosthetic. With the ROM-Pedal the affected leg makes a full pedal rotation with a smaller motion. The ROM-Pedal is adjustable and ensures that the leg extension remains normal but the knee bends less.
It allows people with knee problems or people recovering after a knee prosthetic operation to cycle in the correct position. In other words, with your saddle at the right height and the balls of your feet on the pedals!
The video shows clearly how it works.
