Folding bicycle design background and significance

Folding bicycle design electric trike and significance of the bike as a short walking and leisure tool is irreplaceable by other means of transport function [1]. But urban development lead to traffic congestion, vehicle storage area is insufficient, lack of bicycle parking places and stolen Folding electric bikes is very serious situation, pressing for bicycle take up less space, easy to carry. The emergence of folding bicycles, better solve the above problems. The current folding bicycles, folding main purpose is to reduce the occupied space, function is relatively single, not through simple changes with other functions; At the same time around the folded way of folding, folding after modelling is generally quite rough, like a scrap of bike, its outstanding, bones and muscles exposed edges and corners, no folding locking device, can't support independently and stand down. To make up for the above defects, this paper designs a new type of multifunctional folding bicycles. The folding bikes "four with a car", in addition to general bicycles instead of walking or fitness function, but also as a shopping cart, after the folding luggage trailer and seat use, unifying the cycling, shopping, transportation and rest. 2 folding bicycles, folding folding scheme analysis scheme is the core issue of folding bike design. "In today's society, because the problems such as pollution, traffic congestion, on the design of the urban traffic is convenient and environmental protection become a big trend, city appeared a lot of folding bicycles." Folding bicycles form [1] is clever and green environmental protection, can save a space and meet the needs of people fast rhythm life, ideal short-distance transportation for the future. Analysis of folding bicycles, folding way, set out from human and beautiful,
