We struggled to learn how to ride a bicycle as a young man. We had a machine of jumps and wounds. In the future our sufferings could be useless if the new pedals proposed by Alenax Corporation were to go ahead. The old rotary pedals have been finished.
Traditional pedals are replaced by two levers. Both levers are connected to the rear wheel through the two chains. When the driver makes force on one of the levers, the chain drives the pinion and raises the other pedal: the movement of the legs is not rotary but rolling.
According to the inventors, this method is the most efficient way to transmit strength to the wheels and the most economical from the point of view of fatigue. In America there is already a rope. In Europe soon.
