Abstract

A detachable multifunctional electric bicycle flat tire booster is designed according to the characteristic that after an electric bicycle flat box step is put down, tires are lifted off and the flat box step can support an entire bicycle body. Due to the fact that box steps are different in variety and various in shapes, a universal small support needs to be arranged between the box step and universal wheels to fix, not only can an inner tire and an outer tire be protected, but also fast pushing to front, back, left and right can be achieved, and also people or heavy objects within 100 kilograms can be loaded. Considering the conditions that the electric bicycle is not provided with the box step, or the electric bicycle is provided with the box step and a front wheel has a flat tire, the booster is additionally provided with a ring-shaped support seat which can be stretched on the length. The support seat can clamp the tires and hubs and enable the tires and the hubs to be not rotated, the two universal wheels are fixed on the ring-shaped support seat through the universal small support, and a bandage is used for looping, and then using can be achieved. The electric bicycle flat tire booster is not limited by road conditions, weather and vehicle loads, and good in universality and capable of being dismounted quickly, dismounted parts can be used for locking a battery cell and a basket, for hanging a raincoat to dry and the like.
