Abstract
The utility model relates to a lever drive bicycle. A first connecting rod is driven to take the lifting motion through rotating an eccentric rotating disk so as to generate power to drive a supporting frame bearing outer sleeve, a second connecting rod and a flat spherical outer sleeve base which are sequentially connected with the first connecting rod. The eccentric positions of two groups of eccentric rods are fixed on a sliding block fixing frame up and down. When the lever drive bicycle moves upwards, the group of the eccentric rods with the lower eccentric position drive a flywheel rotating disk to rotate, and the group of the eccentric rods with the upper eccentric position slide in an emptying mode; and when the lever drive bicycle moves downwards, conversely, the two groups of eccentric rods alternately drive the flywheel rotating disk to rotate so as to drive a straight tooth outer mother wheel and a straight tooth inner flywheel to rotate. By a bicycle drive mechanism, the problem that when a chain is used to drive, the chain is easy to drop off and break be solved, the effect of saving labor can also be achieved by a lever principle, and the bicycle can run forwards whatever the bicycle is pedaled forwards or backwards. The lever drive bicycle can be widely used for people to go outside as a practical transportation vehicle.
