【導讀】人類的蓬勃發(fā)展的是因為科學技術的進步。有時候，成功似乎是非常，非常。即使是一些在昨天看似完全不可能完成的事情，而在今天就可以完成。一代的汽車具有視頻。能舉出來的例子是無止境的。但還有一個需要列舉的例子。有人說，未來的燃料一定會是電力這種資源。許多汽車制造商都正在積極。地投入一系列有關電力驅(qū)動的電動載體的研究，并且想親自證實這一觀點。但是如果你在自行車上裝配電動馬達，使它變成一輛小型電動自行車，那么你將會得到一種非常緊湊，方便的交通工具。者的喜愛，所以我想沒有人會否認這個事實的真實性。乘坐電動自行車可以被歸納為是一種特定類型的運動。行車或具備汽油發(fā)動機的摩托車，它是獨立的個體。需要駕駛執(zhí)照、保險和有關登記號碼的收據(jù)。不同的模式進行完全的充電。自行車裝配上馬達的好處有一大堆，其中之一是易于維護。目前，電動自行車已成為所做工作的一部分。
【正文】 ectronic parts of the bikes are designed to be trouble and maintenance free. 5. How can I tell a good electric bike from a bad electric Bike? Clicking here will take you to our buying guide! 6. Does the battery recharge when I pedal? We are asked this question by almost every customer. The answer that applies to most electric bicycles is no but you do preserve the battery power by pedalling! There are a few exceptions using regen for braking but this technology adds weight, more expensive ponents, and the benefit is pretty negligible considering bike stopping distances and the power lost in the system. Regen is slang for “ Regenerative” . Some motors (direct drive) can generate electricity when the rider propels the bike by pedalling, or while when going down hill or braking. A motor and a generator are actually the same thing. If you turn a motor shaft, you will generate electricity. If you energized a generator you would get a motor. So on an electric bike that does not have a plaary transmission, or a freewheel between the motor and the hub, and has a controller that will allow the motor to bee a generator – you can have regen. Regen, however, is not as useful as it sounds. To recharge the bike while riding requires you to ride a long way against the resistance of the motor. You must create more work (due to efficiency losses) to recharge the battery than the work that the energy in the battery can do through the motor. (Awkward to explain.) Basically, you have to work harder to charge the battery enough to propel the bike 10 miles than it would have taken you to ride 10 miles by yourself. So for most purposes, Regen captures a small, very small, amount of extra range. Maybe 50 meters in a 20 mile ride. 7. Are there any UK laws I need to be aware of? The UK law differs slightly from the EU law and hence there is some confusion but if you adhere to the following you should be acting within our current regulatory guidelines. average continuous motor power output no more than 200 watts maximum speed under power 15 mph. must have functioning pedals. the use of a throttle is currently allowed. weight must not be more than 40 kg unless a tandem or tricycle. riders age must be at least 14 years of age.
