The green pony electric car is not good, either this or that. The attitude of looking for a business is not good, and the battery is not good. The 60V you bought can only ride 50 kilometers, and when you bought it, you said it was 90 kilometers. It's almost the same to change a battery. I went to the merchant and ignored me. Alas, the green pony is not as good as the 48V rose I bought before, and it can run 70 kilometers.
