Description

Standing is ridden bicycle without seat

Technical field

The utility model is related to bicycle, and in particular to a kind of to stand the bicycle ridden.

Background technology

The wheelspan of common two-wheeled cycle is larger, and storage is got up to compare and taken up room, and this bicycle does not typically have Folding function, it is impossible to reduce volume in order to be stored in interior.People go up a slope in cycling or loading capacity can stand when larger To be ridden, so the weight of whole body can be all pressed on pedal, reinforcing and the purpose for accelerating can be reached.From Driving sportsman can also adopt the posture ridden of standing sometimes for acceleration, there is presently no one kind and ride dedicated for standing Bicycle.The speed change of ordinary bicycle is smaller, it is impossible to which realization is quickly ridden, it is impossible to reach the purpose of body-building of quickly riding.

The content of the invention

It is little that the purpose of this utility model is to provide a kind of space of taking up an area, and can fold up storage, is exclusively used in standing and rides, Gear ratio is bigger, it is possible to achieve the standing of body-building of quickly riding is ridden bicycle without seat.

Technical solution of the present utility model is：It includes vehicle frame, two front-wheels and a trailing wheel, two front-wheel difference The two ends of front axle are rotatably installed in, are provided with that lower end is fixed on front axle, middle part and vehicle frame front end rotate in the middle part of front axle Coordinate, upper end is located at vertical shaft above vehicle frame, the upper end of vertical shaft be connected with lower end be connected with vertical shaft, upper end bogie upward, Trailing wheel is located at the rear portion that the rear of two front-wheels is rotatably installed in vehicle frame, and the position of rear axis is provided with and is rotatably installed on vehicle frame Axis, the two ends of axis are separately installed with free end and are respectively equipped with the left car of pedal turns and is turned with right car, fixed peace on axis Equipped with rear sprocket wheel, vehicle frame is provided with and is rotatably installed in duplicate sprocket on vehicle frame positioned at trailing wheel front, rear sprocket wheel by chain with The sprocket wheel one of duplicate sprocket is connected, and the flywheel with trailing wheel one-way clutch is provided with trailing wheel, and freewheel sprockets are by chain and duplex The sprocket wheel two of sprocket wheel is connected.

It is of the present utility model to have the technical effect that：Its occupation of land space is little, can fold up storage, special not with vehicle seat Ride in standing, ride more laborsaving, gear ratio is bigger, it is possible to achieve body-building of quickly riding.It is turned to using two front wheels, single rear wheel Driving structure, rides more steady, and handlebar can be folded back onto on trailing wheel and erect to deposit by it, and storage gets up more to pacify It is complete stable, take up room less.It adopts two-stage chain transmission mode speed change, rides speed faster, and acceleration effect is more preferable, It is more beneficial for body-building of riding.

The utility model has the characteristics that：

1st, stand and ride, without vehicle seat, riding speed is faster；

2nd, small volume, floor space is less when standing up, and floor space is less than common folding bicycle；

3rd, it is lightweight, it is downstairs and easy to use in carrying；

4th, structure is special, rides more laborsaving；

5th, center of gravity is low, rides easy for going up and down, safer；

6th, can haul away as draw-bar box after folding up, can with oneself haul and go shopping, take advantage of public transport, sit ground Iron, takes up room little, mobile more convenient.
