Haojue has a large displacement. In Hefei, I think this kind of car can also be licensed as a moped. Please tell me which car with curved beam is better, how big the displacement is and how much it costs. Haojue's cost displacement is 1 10. You must get a motor vehicle driver's license and an e driver's license. Now * * * three models, HJ110-AHJ10-2 CHJ110-2D, are priced at around 4,500,5,500 and 5,000 respectively. The higher the price, the higher the performance and the better the quality of the latter two models.
