Description
Technical field
The present invention relates to Electronmotive Force bicycle field, particularly disclose a kind of Foldable cellular Electrical Bicycle.
Background technology
The manufacturing of bicycle and use have had the history of upper a century, the characteristics such as that bicycle has is light, healthy, Green Travel, but the quickening along with people's rhythm of life, bicycle and man can't satisfy people's life and work requirement, in each big city, it is more general that the use of battery-driven car seems, but battery-driven car is subject to the impact of its electrical equipment, volume is larger, carrying inconvenience.
Take up space although known Folding Bicycle can reduce institute, this Folding Bicycle can't adopt Electronmotive Force.And a kind of battery-driven car that can fold is not provided on market yet, and make it collapsible as bicycle, the volume after making it folding can be put common knapsack into, and lightly again can carry for a long time to deal with the battery-driven car that long journey needs.
In general, normally used battery-driven car in the city, no matter brand or quality, all have a shortcoming, and it still occupies certain space when not using battery-driven car exactly.Why light and handy portable Electrical Bicycle becomes more and more important, and is because it can provide a kind of individual transportation mode to fill up the unappeasable rising demand of mass transit system.This demand is obvious especially in situation on and off duty, working clan at suburb, township inhabitation urban work, often need to go on foot bus or subway station, after experiencing one section crowded public transport means every day, arrived potential range work place, station, destination and also had the stretch journey.If the use battery-driven car on the one hand need to take how to place battery-driven car in the accommodation into account, is again a larger problem with subway on the battery-driven car band on the other hand, particularly crowded only with the railway carriage of standing in.Although abroad some bus provides cycle frame and places bicycle for the passenger, this vehicle frame definitely is unable to cope with the huger battery-driven car of build.
Another field that need to break through is to allow the less people of body forces also can use portable electric bicycle, reach this purpose, and battery-driven car needs lighter weight, less volume.Because battery-driven car is light than automobile, heavier than bicycle, different from the closed state of automobile, it is larger that battery-driven car is placed on outdoor stolen risk, for the purpose of safety, the general hope of user can be laid battery-driven car at home or is indoor, but a battery-driven car is usually extremely heavy, it is very inconvenient to carry,, the people Lai Shuoshi that be short of physical strength quite heavy weight slim and frahile for an idiotype.So weight issue makes the part masses fail to enjoy the benefit of using battery-driven car to bring.
On the use aspect of battery-driven car, the reason that the battery-driven car Occupation coefficient rises is many times that the user stores battery-driven car in advance in order to using when bus or railway can not provide service.In this case, just need more parking space continuously.Yet in the big city, oneself is less and less for employee's office space.For dealing with above-mentioned all demands, depositing with carrying these two problems of battery-driven car is all problem demanding prompt solutions.
