Patent attributes
The present invention provides a caterpillar type bicycle, comprising a bicycle frame, a saddle, a steering handle, and a sprocket pedal power mechanism, as well as a caterpillar type driving structure (A) and a multi-functional switchable front guide mechanism (B), wherein the caterpillar type driving structure (A) comprises a driving wheel drivingly connected to the sprocket pedal power mechanism, an auxiliary wheel pivotally supported on the tail of the bicycle frame, a caterpillar provided on the driving wheel and the auxiliary wheel, and a connecting rod for determining the positional relation between the driving wheel and the auxiliary wheel; the multi-functional switchable front guide mechanism (B) comprises switch means fastened to at the distal end of the a front rod of the bicycle frame, a front guide rolling wheel rotatably connected to a pivotal shaft provided by the switch means, and a front guide sliding board fixedly connected to two hinge support points provided by the switch means. When the multi-functional switchable front guide mechanism (B) is in the first state, the pivotal shaft is at a level higher than the two hinge support points that are at the same level so that the front guide rolling wheel is off the ground and the front guide sliding board touches the ground in a flat manner; when the multi-functional switchable front guide mechanism (B) is in the second state, both of the two hinge support points are higher than the pivotal shaft such that the front guide rolling wheel touches the ground and the front guide sliding board is off the ground.
