All the weight is on the motor, which provides maximum traction in different conditions. Noise levels are lower on the rear hub, because of the extra weight on the wheel vibrations from other parts.

Drawing of Rear Drive Motor DGW25LS:
Application of Mid Motor
Shengyi hybrid motor
makes the ebike center of gravity reasonable. However, China dc hub motor
is placed on the front and rear wheels, the center of gravity of the ebikes will not be balanced. Therefore, the weight distribution of the battery must be used to share the weight of the motor. The ebike center of gravity of mid motor is in the middle of the ebike. When the ebike is driving fast, it can play a role in front and rear balance.
The mid motor can change speed conditions. At the same time, the torque is higher, the acceleration is fast, and the climbing ability is strong. The dust-proof and water-proof performance of mid motor is also stronger.
