Abstract
This new bicycle propulsion system is based on propulsion of a bicycle (12) by means of a system consisting of a pedal (4) intended to receive the toes such that the force obtained by pedaling with this pedal (4) is transmitted to the drive wheel (8) as a result of the elongated crank (3), causing circular movement, increasing the diameter of the circumference made by the pedal (4) and sprocket wheel (6), wherein this sprocket wheel (6) communicates with the pinion (10) by means of the chain (11).
Claims3
A bicycle propulsion system and product thus obtained, of the type used to propel a bicycle or any bicycle derivative propelled by the force of the leg muscles, characterized in that elongated cranks (3) attached to a sprocket wheel (6) incorporate a pedal (4) which receives the user's toes such that when pedaling, greater pedaling force is transmitted to the drive wheel (8) by means of the pinion (10), which communicates with the sprocket wheel (6) by means of the chain (11).
A bicycle propulsion system and product thus obtained according to claim one, characterized in that the frame (1) of the bicycle (12) has been elongated considerably.
A bicycle propulsion system and product thus obtained according to claim one, characterized by having the pedals arranged further back and higher up so as to allow the elongated cranks to carry out the desired movement.
