Further, the bottom end of the cylinder is provided with a flange, a front wheel is arranged between the flanges, the front wheel is fixed through the flange, and the mounting is firm and the dismounting is convenient.

Furthermore, a small bell is sleeved at the handle of the front frame.

Further, the seat is installed to horizontal pole intermediate position department, the seat upper surface is provided with the one deck foam-rubber cushion, and the foam-rubber cushion makes the seat when taking, and the comfort is higher.

Furthermore, the cushion block is made of rubber and is in a cylindrical shape and tightly attached to the inner wall of the cylinder, and the cushion block can play a role in increasing air tightness.

The utility model has the advantages that:

(1) the shock absorber can absorb the impact force on the whole frame, so that the frame is prevented from deforming, and the practical service life of the bicycle is prolonged.

(2) The spring can absorb the impact force in the preceding frame, plays the cushioning effect, reduces automobile body shake range and improves and ride.
