Problems solved by technology

The bicycle is an environmentally friendly and convenient sports vehicle, but the existing bicycle has a single power source, and only the pedal crank sprocket rotates to generate power, so the legs are tired and the speed cannot be fast. This defect cannot satisfy most people. travel and commuting needs

Abstract

The invention provides a foot-stepping and hand-cranking double-driving bicycle capable of combining foot-stepping driving and hand-cranking driving. According to the bicycle, a box body, gears, hand-cranking cranks, a switch, bicycle handlebar covers and a clutch are additionally arranged in a bicycle front frame through design. The effect of front wheel hand-cranking driving is achieved through the mutual cooperation relations of all parts such as shafts and bearings, a foot-stepping travelling mode can be switched into combination of foot-stepping driving and hand-cranking driving, and thus the travelling speed of the bicycle is increased; and meanwhile the leg strength fatigue intensity of crank chain wheel foot stepping can be relieved so that travelling of the bicycle can be more rapid and relaxing.

Description

technical field [0001] The invention relates to a pedal-hand-crank dual-drive bicycle in the field of vehicles, and more specifically, relates to a bicycle with a combination of a pedal-drive and a hand-crank drive that can travel extremely fast. Background technique [0002] At present, known bicycle structure is made up of vehicle frame, front wheel, rear wheel, front axle, rear axle, front fork, handlebar, flywheel, crank sprocket wheel, chain, saddle and car killing device. The source of power is that people's feet move the crank sprocket to drive the chain, and the chain drives the flywheel to rotate the rear wheel, thereby achieving the effect of forward movement. The bicycle is an environmentally friendly and convenient sports vehicle, but the existing bicycle has a single power source, and only the pedal crank sprocket rotates to generate power, so the legs are tired and the speed cannot be fast. This defect cannot satisfy most people. travel and needs when commuting...
