A kind of body-building bicycle
Technical field
The present invention relates to a kind of body-building bicycle, a kind of people uses four limbs to have an effect and drives the body-building bicycle of front and back wheel in running form specifically.
Background technology
China is bicycle big country, more more and more payes attention to health in conjunction with contemporary people, athleticism.Body-building is just becoming more and more popular.This invention can temper upper and lower extremities preferably, the sense of equilibrium.Define the implication of new cycling motion, define new bicycle big country.
Summary of the invention
The object of the invention is in running form, to use four limbs to have an effect by a kind of people of realization and drive the body-building bicycle of front and back wheel, make people rationally temper upper and lower limbs while enjoying the enjoyment of riding.
The technical solution used in the present invention is as follows:
A kind of body-building bicycle, is characterized in that: this body-building bicycle comprises handle rack 1, front-wheel 2, trailing wheel 3, pedal travel device 4, vehicle frame 5; Described pedal travel device 4 is located on vehicle frame 5, and between front-wheel 2 and trailing wheel 3; One end of vehicle frame 5 is provided with front-wheel 2, and the other end is provided with trailing wheel 3; Described handle rack 1 comprises the first expansion link 11, is positioned at the holding rod 12 at its two ends and mobile jib 13; Described mobile jib 13 comprises the first pole 131, second pole 132, second expansion link 133; First pole 131 is connected with the second pole 132 by the second expansion link 133; The other end of the first pole 132 is mobilizable to be located on the first expansion link 11; The other end of the second pole 132 is provided with wheel word 134; Described wheel word 134 is connected with front-wheel 2 by blockchain 135; Described pedal travel device 4 comprises crawler belt 41 and drives the first roller 42 and the second roller 43 of crawler belt, and described first roller 42 and the second roller 43 are arranged on vehicle frame 5; Vehicle frame 5 is provided with the first gear 32, and described second roller 43 is connected the first gear 32, first gear 32 by belt and connected the second gear 43 be arranged on trailing wheel by chain 31.
Motion wheel word 111 is provided with between first pole 131 and the first expansion link 11.
Described vehicle frame 5 adopts aluminum alloy material.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in figures 1 to 6, a kind of body-building bicycle, this body-building bicycle comprises handle rack 1, front-wheel 2, trailing wheel 3, pedal travel device 4, vehicle frame 5; Described pedal travel device 4 is located on vehicle frame 5, and between front-wheel 2 and trailing wheel 3; One end of vehicle frame 5 is provided with front-wheel 2, and the other end is provided with trailing wheel 3; Described handle rack 1 comprises the first expansion link 11, is positioned at the holding rod 12 at its two ends and mobile jib 13; Described mobile jib 13 comprises the first pole 131, second pole 132, second expansion link 133; First pole 131 is connected with the second pole 132 by the second expansion link 133; The other end of the first pole 132 is mobilizable to be located on the first expansion link 11; The other end of the second pole 132 is provided with wheel word 134; Described wheel word 134 is connected with front-wheel 2 by blockchain 135; Described pedal travel device 4 comprises crawler belt 41 and drives the first roller 42 and the second roller 43 of crawler belt, and described first roller 42 and the second roller 43 are arranged on vehicle frame 5; Vehicle frame 5 is provided with the first gear 32, and described second roller 43 is connected the first gear 32, first gear 32 by belt and connected the second gear 43 be arranged on trailing wheel by chain 31; Motion wheel word 111 is provided with between first pole 131 and the first expansion link 11; Vehicle frame 5 adopts aluminum alloy material.
The present invention realizes people in running form, to use four limbs to have an effect drive the body-building bicycle device of front and back wheel.In use, center of gravity keeps balance to people.Both feet are trampled and are run on crawler belt, drive roller to rotate, then by the first gear driven chain, trailing wheel 3 are rotated, the gravity of grantee on crawler belt.Hands grasping is naturally had an effect run-up on holding rod 4, drives front-wheel 2, the track by human body running bimanual movements track is had an effect naturally and moves back and forth, the formation of this three-dimensional track by wheel word; First pole 131, second pole 132, second expansion link 133, wheel word 134; The fixation locus formed interacts.
The present invention can be ridden by a kind of running, when driving bicycle to advance, reaches the object of body-building, makes people rationally temper upper and lower limbs while enjoying the enjoyment of riding.People completes the driving to bicycle in intimate form of naturally running.Bicycle itself is made to adapt to the proper motion attitude of people.Both arms, both legs rule continues to have an effect, and has good body-building effect.
