1, the speed transition should be smooth, start without impact, the wheel rotation should be flexible, no sense of stagnation, the wheel rotation sound is soft, no noise, the brake should be moderate tightness, reliable braking force. 4) Check whether the auxiliary functions (such as power display, speed, mileage display, etc.) are normal, and whether the accessories, chargers, certificates, manuals and warranty cards accompanying the car are complete.
2, ensure the battery storage box lock safety! The storage compartment of the battery car usually coexists with the battery, so the choice of lock head is crucial. Observe the type carefully to ensure that adequate protection can be provided to prevent battery theft. Preference is given to the battery car with disc brake! -- The brake system of the electric vehicle cannot be ignored. The disc brake can stop quickly and safely, so be sure to check whether the battery car is equipped when purchasing.
3, the shock-proof effect of the battery car determines the comfort of your riding the battery car. If the shock effect is not good, on some uneven roads, the cycling experience is not good at all. The cushion softness of the battery car will increaseAdd a sense of experience while cycling; Secondly, check whether the cushion material is waterproof, if it is not waterproof, it will be easy to have a very embarrassing problem in rainy days.
