Description
Technical field:
The utility model relates to a kind of bicycle.
Technical background:
The mode of driving of tradition two-wheeled cycle makes the people when driving, time is a little longer just can feel tired, and this is that the seat appearance is very uncomfortable because its seat is very narrow, also have its pedal length to be restricted, can not make full use of lever principle and alleviate power consumption when driving.In addition, its stability is bad, poor stability when driving.Be exactly that the space is limited in addition, be not easy to install bicycle shed, can not satisfy people and wish the hope that under any weather condition, can both drive.
Summary of the invention:
The purpose of this utility model is: provides a kind of bicycle shed can be installed, and can be with the good bicycle of stability that drives than comfortable posture, to satisfy people's needs.
The utility model is to constitute like this: it is by vehicle frame (1), pedal (2), front-wheel (3), trailing wheel (4), front axle (5), axis (6), rear axle (7), backrest seat (8) is formed, and axis (6) is divided into left and right sides two-semiaxle (9), (10), is contained in the centre of vehicle frame (1), front axle (5) is contained in the front portion of vehicle frame (1), rear axle (7) is contained in the rear portion of vehicle frame (1), and backrest seat (8) is contained on the rear axle (7) of vehicle frame (1), and front-wheel (3) is contained in the front end of vehicle frame (1); Two pedals (2) are connected by the preceding left and right sides flywheel (11), (12) that are contained in chain drum, the chain on left and right sides two-semiaxle (9), (10) and be contained on the front axle (5) respectively, be contained in the middle of the front axle (5) in before flywheel (13) connect by chain and be contained in flywheel (14) in back in the middle of the rear axle (7), flywheel (14) drives rear chain disk (15) by rear axle (7) in the back, and rear chain disk (15) drives trailing wheel (4) by chain, flywheel.
