Problems solved by technology
Existing bicycles have the following shortcomings: the riding speed is slow, and the driving speed of both feet is limited, resulting in a lower riding speed, generally below 20 km / h. Therefore, people often change to ride electric bicycles or motorcycles in order to pursue speed. However, the batteries of electric bicycles will cause environmental pollution, and motorcycles need to consume fuel, a non-renewable resource.

Description
technical field [0001] The invention relates to the technical field of bicycle manufacture. Background technique [0002] Bicycles in the prior art mainly include a crankshaft, the crankshaft is fixed to the rotating shaft, the rotating shaft is fixed on the vehicle frame, crank arms are respectively fixed at both ends of the rotating shaft, pedals are installed on the crank arm, and the crankshaft is connected to a chain through a chain. The outer ring of the one-way flywheel is connected by transmission, and the inner ring of the one-way flywheel is fixed to the rear wheel of the bicycle through the rear wheel shaft, and the rear wheel shaft is supported on the frame; The disc drives the rear wheel to rotate and drives the bicycle forward. The one-way flywheel is composed of an outer ring, an inner ring and a one-way transmission mechanism arranged inside. The inner ring and the outer ring can slide in one direction and lock each other in the reverse direction. Existi...
