The major advantage of torque-assisted cycling is energy saving and environmental protection: due to the participation of manpower, the reduction
The power consumption of the lithium battery, a limited energy source for vehicles, has been eliminated. Compared with the pure electric drive method, in
Under the condition of ensuring the same continuation mileage, the battery capacity can be reduced by half, and the battery volume and weight
The quantity and cost can be greatly reduced, the power and weight of the motor can also be reduced, and the weight of the vehicle will be significant
reduce. In the case of the same battery capacity, the mileage can be doubled on a single charge.
Correspondingly, the number of times the battery needs to be charged within a certain period of time will be greatly reduced.
The electrical interval and battery life will be significantly extended.
In addition, the advantage of human-assisted riding is that it can also exercise and fitness, which can greatly reduce the full electric
