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.

The invention claimed is: 1. A multi-functional caterpillar type bicycle, comprising: a bicycle frame, a saddle, a steering handle, and a sprocket pedal power mechanism; further comprising: a caterpillar type driving structure (A), comprising a driving wheel (1) drivingly connected to the sprocket pedal power mechanism, at least one auxiliary wheel (2) pivotally supported on a tail of the bicycle frame, a caterpillar (3) provided on the driving wheel (1) and the auxiliary wheel (2), and a connecting rod (4) for determining the positional relation between the driving wheel (1) and the auxiliary wheel (2); a multi-functional switchable front guide mechanism (B), comprising switch means fastened to a distal end of a front rod of the bicycle frame, a front guide rolling wheel (5) rotatably connected to a pivotal shaft (7) provided by the switch means, and a front guide sliding board (6) fixedly connected to two hinge support points (8, 9) provided by the switch means; characterized in that the switch means in the multi-functional switchable front guide mechanism (B) provides a first switch state and a second switch state; in the first switch state, the pivotal shaft (7) is at a first level higher than the two hinge support points (8, 9) so that the front guide rolling wheel (5) is off the ground and the front guide sliding board (6) touches the ground in a flat manner; in the second switch state, both of the two hinge support points (8, 9) are at a second level higher than the pivotal shaft (7) such that the front guide rolling wheel (5) touches the ground and the front guide sliding board (6) is off the ground. 2. The multi-functional caterpillar type bicycle as claimed in claim 1, characterized in that a speed change controller and a brake controller are attached to the steering handle. 3. The multi-functional caterpillar type bicycle as claimed in claim 1, characterized in that the caterpillar type driving structure (A) comprises more than one said auxiliary wheel (2).
