    Very satisfied

    My friend and I bought a new electric bike almost at the same time, with the same style, but the price he bought at the time was much cheaper than mine, which made me instantly feel that I was pitted. But when I received the goods , I found that my bike was much stronger than his, very powerful and can bring me the speed I want.
