Description

Technical field: [0001] This 3-second folding portable dual-purpose electric power-assisted bicycle is a very simple, fast, time-saving and labor-saving folding operation, and is most suitable for primary school students, women, and elderly people. The utility model is suitable for people to commute to and from get off work and for students to ride to and from school. The utility model has two functions and can be used as a bicycle by quickly removing the electric power assist device. The lightweight folding bicycle does not have electric booster and shock absorbing devices, so it is convenient to carry when going out, traveling and taking other means of transportation, and it is also convenient to carry in the trunk of the car and start riding at any time. It can also be pushed and walked after being folded. Background technique: [0002] At present, there are many kinds of folding bicycles and electric power-assisted bicycles on the market, which have expanded the purchas...
