1. Determine the choice of electric vehicles according to your own needs. For example, as long as the mileage you use for commuting can meet the standard, everything else can be done. If you want to be cool, you must buy a tall one.
2. Choose what kind of battery to use according to your own needs. If you need to train frequently, the lighter the better, so use lithium batteries.
3. Choice of comfort and appearance. If there are requirements for comfort, you should choose large, medium and small vehicles according to your own preferences to suit your own needs.
4. Finally, the choice of mileage and speed. If you commute, it usually takes only three days. For example, 48V 12 ah battery 350W motor, the new national standard electric bicycle can run about 40 kilometers. A 48V 20ah battery and a 350W motor can run more than 70 kilometers. If the pursuit of speed, then the motor power must meet the corresponding requirements. The output power is 800W and the speed is about 40 km/h; 1500W output, the speed is about 52; 2000W output, rotating speed about 58; 3000W output, rotating speed about 65.
5. Compare the cost performance. If the price is right, you can buy it. If it is not ideal, some unnecessary performance requirements must be reduced to obtain higher cost performance.
