Problems solved by technology

However, this type of wheel motor needs to be equipped with a gear gearbox. When the gears mesh and rotate at high speed, mechanical wear is easy to occur, which affects the life of the gearbox, motor and battery.

Complex structure, high procurement cost, and high cost of replacing motor and battery later

Various factors lead to an increase in the sales price of the product and an increase in the cost of use, which is not conducive to promotion and sales in the market
