Abstract

The invention provides a lever-assisted bicycle and a lever-assisted multi-wheel vehicle, and relates to a bicycle. The bicycle comprises front and rear wheels, a frame, a saddle, handlebars, left andright pedals, left and right levers, left and right chain rods, a chain, a large chain wheel, a small flywheel and a hub. The left and right levers are movably hinged with the left and right chain rods; the left and right chain rods are movably hinged with left and right curved bars; the left and right curved bars are connected with the large chain wheel; the large chain wheel is arranged above arear wheel, the large chain wheel is rotatably connected with the small flywheel through a chain; the small flywheel is connected with the hub and the rear wheel; the left and right pedals are mounted at front ends of the left and right levers, and fulcrums of the left and right levers are positioned on left and right sides of a rear wheel center shaft; and when the front ends of the levers moveup and down, the chain rod is driven, the chain rod drives the curved bar, the curved bar drives the large chain wheel, the large chain wheel drives the chain, the chain drives the small flywheel, andthe small flywheel drives a hub rear wheel to rotate forwards in cycles. The lever-assisted bicycle is simple in structure, labor-saving, power-assisted and rapid.

Description

technical field [0001] The present application relates to the technical field of pedal bicycles, in particular to a lever-assisted bicycle and a lever-assisted multi-wheeled vehicle. Background technique [0002] The current traditional bicycles are all pedals connected to the pedals, the pedals are connected to the large sprocket, the rotation of the large sprocket drives the chain, the chain drives the small flywheel on the rear wheel, and the small flywheel drives the rear wheel to rotate. This transmission method can make The bike gets around, but not very effortlessly. [0003] The object of the present invention is to provide a lever-assisted bicycle and a lever-assisted multi-wheel vehicle with simple structure, labor saving, power assistance and faster walking speed. Contents of the invention [0004] The technical solution adopted by the present application to achieve the above object is: a lever-assisted bicycle and a lever-assisted multi-wheeled vehicle, compri...
