Abstract

The invention relates to a seat type axle-driven bicycle which comprises a bicycle front wheel assembly, a rear wheel assembly including a rear hub and a flywheel, a frame, a middle axle driven mechanism including cranks and pedals, a rear axle driving mechanism and a backrest seat. The bicycle is characterized in that the middle axle driving mechanism is arranged between a middle axle bottom bracket shell and a front fork riser pipe, a lower beam of the front fork riser pipe between the front fork riser pipe of the frame and the middle axle bottom bracket shell is fixedly connected with a frame-axle middle joint, and the frame-axle middle joint supports a middle axle of the middle axle driven mechanism by a bearing, and the middle axle driving mechanism is connected with the rear wheel assembly by an axle-driven mechanism. The seat type axle-driven bicycle of the invention keeps the rear-wheel driven structure style, changes the chain-driven structure into axle-driven one and improves the drive efficiency. At the same time, the improved seat can be adjusted not only in the vertical direction but also in the anterior-posterior direction, so that a rider can comfortably rides on the seat against the seat back, thereby thoroughly preventing critical organs at the crotch of people from being hurt. Besides, the invention has the advantages of labor saving for driving and nimble, smooth and safe operation and is comfortable to ride and flexible to steer.

Description

technical field [0001] The invention belongs to bicycles, in particular to a seat type shaft transmission bicycle. Background technique [0002] At present, there are various forms of bicycles on the market, basically adopting rear wheel drive and chain transmission. That is, the rear wheel is active theory, and the rider pedals the flywheel to rotate through the wheel disc, chain and rear wheel to drive the front wheel to make the car move forward. The bicycle with the rear drive structure makes the rider's center of gravity all fall on the crotch through the triangular saddle, which is easy to damage the vital organs of the rider's crotch, and pathological changes will occur for a long time. Especially harmful to young people. The patent application (patent number: ZL200920095333.1) discloses a patent for a front-drive chainless gear transmission bicycle. The side of the front axle skin is equipped with a gear transmission driving device and a pedal mechanism, so that ...
