问用英语介绍普通自行车和电动自行车各有什么利弊？

Everything has its advantages and disadvantages and the same is true with the E-bike (electric bike) and the regulare bike. The good thing about the E-bike is that you don't have to peddle to get your bike going while for the regular bike you have to peddle to get it moving. You can of course save a lot of energy when you have to travel a long distance to get to work. And it can also go much faster than the regular bike. But nothing is perfect. It could be a total disaster for you if it runs out of its power in the middle of the way and you have a harder job to get it home. For a regular bike,you never have to worry about that. And it can give a good exercise everyday if you have to rely on it to get to work. You don't have to go to the gym as you've already had enough exercise by riding your bike to and fro from your home and workplace. The good thing is I have both so I can choose either one for my different purposes.
