Specific embodiment
The technical solution of the utility model will be clearly and completely described below.The utility model is using friendship up and down
For the treadle stepped on, instead of the crank mechanism to move in a circle in driving bicycle, the entertaining ridden is considerably increased；Its
Secondary, the treadle of the utility model is long, rides laborsaving, and leg can prevent perambulator disease with free extension to longest.
Trample type bicycle up and down as shown in Figure 1, a kind of, including front-wheel 1 and front axle, rear-wheel 2 and hind axle, front fork 3,
Rear fork 4, crossbeam 6, handle 5, front fork, rear fork, which are respectively corresponded, connects front fork 3 with after with front axle, the affixed connection of hind axle, crossbeam
4 are pitched, seat is set on crossbeam 6；
Setting lead 8 is threaded through 6 lower part of crossbeam, and treadle 9, treadle is respectively set in the 6 lower section left and right sides of crossbeam
It is connected by lead；That is it is respectively arranged with treadle 9 at left and right sides of the utility model bicycle, in the effect of lead
Under, treadle 9 can only control alternately to be trampled up and down.Preferably, treadle can be set tension spring and be connected on crossbeam.
9 one end of treadle is rotatablely connected pedal 10, flywheel 11 is arranged on the hind axle, 9 other end of treadle passes through biography
Dynamic device connects flywheel 11, for driving flywheel 11 to rotate when pedal moves up and down, is further driven to the rotation of rear-wheel 2.It needs
Illustrate, in rotation, front axle and hind axle maintain static bicycle wheels, and front and back wheel is socketed by axle sleeve
On front axle and hind axle, this is well-known to those skilled in the art；Meanwhile as shown in Fig. 2, flywheel by 13 He of ratchet
Pawl 12 forms, and the driving capability being able to maintain in a rotation direction, this will not be repeated here.
As a kind of preferred embodiment of the utility model, as shown in figure 3, the transmission device is plate tooth, plate tooth
