| 摘要 |
The invention foresees a kinematic device to be applied to a normal bicycle, consisting of a pair of bars (1, 2) connected by means of pivots (17, 16) with the cranks (9, 10), said bars ending at one end with inclined components constituting the connecting rod (7, 8), the bicycle pedals (25, 24) being connected with them, and at the other end the the cylindrical ends (3, 4) being guided by tube-shaped components (5, 6) fastened, so they can oscillate to the back fork (13) of the bicycle. Said kinematic device will increase the useful torque to the wheels, the muscular effort remaining the same. |
