Mini electric bicycle

Abstract

The invention discloses a mini electric bicycle which comprises a frame, a middle vertical pipe, a front pipe, a lower pipe and a rear fork. An upper pipe is movably sleeved with the inner side of themiddle vertical pipe, the top end of the upper pipe is extended to the position above the middle vertical pipe and is provided with a saddle base in a threaded mode, the outer side of the middle vertical pipe is movably sleeved with a middle vertical pipe sealing sheet, a front fork vertical pipe is rotationally sleeved with the inner side of the front pipe, the top end of the front fork verticalpipe is extended to the position above the front pipe and is provided with a handlebar pipe in a threaded mode, a front brake is fixedly installed on the handlebar pipe, the bottom end of the front fork vertical pipe is extended to the position below the front pipe and welded to a front fork, the front fork is of a U-shaped structure, a front wheel is fixed to the inner side of the front fork ina threaded mode, and a pedal square pipe is welded to the bottom end of the lower pipe. The design is reasonable, the frame of the electric bicycle is small, simple and small in occupied space, the mini style is represented, manufacturing and machining forming are convenient, therefore, the manufacturing cost is reduced, and convenience is brought to people for use.

Description

technical field [0001] The invention relates to the technical field of electric bicycles, in particular to a mini electric bicycle. Background technique [0002] At present, there are many styles of folding electric bicycles on the market, but mini folding electric bicycles with few folding joints are very rare. After retrieval, the patent document with the application number 201210012397.7 discloses a mini folding electric bicycle, including a body, a rear fork, a seat, a front fork, a V-shaped folding handle, a front wheel, a rear wheel, a human drive mechanism and an electric drive system, the body Including the trunk, front head tube, bottom bracket tube and center tube, the front of the box is connected to the front head tube, the front and bottom of the front head tube is connected to the bottom bracket tube, the rear of the box is connected to the center tube, the rear of the center tube is connected to the rear fork, and the V-shaped folding handle is controlled by t...

Problems solved by technology

[0003] However, the frame of the existing electric bicycle is relatively large, so that the entire electric bicycle body takes up a large space, has a low aesthetic level, is relatively heavy, and is inconvenient for people with small strength. Therefore, we have proposed a mini electric bicycle to solve the above problems
