Description

Use the torsion bicycle driven

The present invention relates to a kind of bicycle.

Existing bicycle great majority are to step on plate under replacing with both feet to provide power that chain wheel is rotated, drive trailing wheel to overtake by chain, the peace seat is put than higher, and danger is bigger, when adding for a long time by bike, crotch portion can produce a uncomfortable sensation with the friction of peace seat.

The object of the invention provides a kind of with the torsion driving, and the seat is lower, rides pleasant, the safe bicycle of people.

For achieving the above object, the present invention installs a front-wheel and two trailing wheels at least on vehicle frame, and front-wheel is a steering wheel, is connected with steering handle, and trailing wheel is a driving wheel, and two flywheels or a bent axle are installed on the wheel shaft.The also movable torsional pole of installing on the vehicle frame, torsional pole can swing back and forth in the scope of 180 degree around an axle center, but optimum range is to be no more than 90 degree.With the hands or both feet twist torsional pole repeatedly, drive trailing wheel by chain or steel rope or gear or link rod and make it to overtake.The seat of a band backrest and backplate also is installed on the vehicle frame, and seat height overhead is no more than the height of trailing wheel.

The present invention uses the torsion of torsional pole to drive trailing wheel to rotate to overtake, and the chassis is lower, and people's center of gravity is also lower, adds the seat that backrest and backplate are installed, and is safer during rider, comfortable.If when refilling device such as motor and battery, just promptly can personnel selection power drive, can use motor-driven again, more flexible, more interesting.Be widely used in the instrument that personal accomplishment is ridden instead of walk.
