I bought my rose in Yibin, Sichuan for 3500 yuan. Seeing that others bought it so cheaply, I cried. I have been riding this car for half a month. Advantages: great strength, fast speed and fashionable appearance. I'm afraid of being stolen everywhere. I bought a 3 kg alloy lock from rayburn, which made me feel at ease. Disadvantages: the front wheel disc brake always has abnormal sound, or clicking sound, or rubbing sound that slightly rubs the wheel. I asked the store's after-sales staff to repair it, and he said it could not be debugged. Since it happens occasionally, I'll put up with it. I hope you don't buy this. Finally, the description of the need for normal load, normal slope and economic speed of 25. I think it should be true that I can run 80 kilometers now. It's really nice of you to meet my answer. I wish I had a reference. Unfortunately, there is a lot of discussion about cars on this network, and no one cares about battery cars. Generally speaking, this brand of car is more expensive than that in 200 yuan.
