The folding electric bicycle that has shock absorption device
The utility model relates to the bicycle field, particularly discloses a kind of Foldable electric force bike that has shock absorption device.
The manufacturing of bicycle has had with use goes up century-old history, characteristics such as that bicycle has is light, healthy, Green Travel, but 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 subjected to the influence of its electrical equipment, volume is bigger, carrying inconvenience.
Take up space though 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 the market yet, and make it collapsible as bicycle, the volume after making it folding can be put common knapsack into, and light and handy again as can to 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 under situation on and off duty, working clan at suburb, township inhabitation urban work, often need to go on foot bus or subway station, experience one section crowded public transport means every day after, arrived potential range work place, station, destination and also had the stretch journey.If use battery-driven car, need take in the accommodation how to place battery-driven car into account on the one hand, be again a bigger problem with subway on the battery-driven car band on the other hand, particularly crowded only with the railway carriage of standing in.Though 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 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, littler volume.Because battery-driven car is light than automobile, heavier than bicycle, different with the closed state of automobile, it is bigger 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 heavy unusually usually, 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 partly popular use benefit that battery-driven car brought of failing to enjoy.
On the use aspect of battery-driven car, the reason that the battery-driven car Occupation coefficient rises, the person of being to use stores battery-driven car in advance in order to using when a lot of 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 and carry these two problems of battery-driven car all is problem demanding prompt solutions.
In addition, the battery-driven car that uses seldom is provided with shock mitigation system at present, and folding bicycle and Electrical Bicycle, because the complex structure of itself, or power supply box takes up space bigger, be difficult to the bicycle shock absorption device reasonably is set, reduced the comfort level that bicycle uses.
