Mid-Mounted Motor and the Front/Rear Motors

Mid-Mounted Motor and the Front/Rear Motors

The main differences between the mid-mounted motor and the front and rear motors are as follows:


Installation location


The mid-mounted motor is installed in the middle of the frame, usually near the pedals.

The front motor is installed at the front wheel hub, and the rear motor is installed at the rear wheel hub.


Weight distribution


The mid-mounted motor can make the weight distribution of the vehicle more even, and the speed distribution is smoother when riding, which is conducive to improving controllability and stability, and improving the riding experience.


The front and rear motors may cause the center of gravity of the vehicle to be biased towards the end where the motor is installed, affecting balance.


Transmission efficiency


The mid-mounted motor is usually connected to the rear wheel through a chain or belt, and the transmission efficiency is relatively high, which can avoid unnecessary energy loss.

The front and rear motors directly drive the wheels, and there may be energy loss in some cases.


Riding experience


The mid-mounted motor can simulate a feeling closer to human riding, and the power assistance is more natural.


The power assistance of the front and rear motors may appear more abrupt.


Climbing ability


The mid-mounted motor performs better when climbing, and can more effectively transmit power to the ground.


The effect of the front and rear motors when climbing may be relatively inferior.


Maintenance difficulty


The installation and maintenance of the mid-mounted motor is relatively complex and requires a high level of technical skills.


The maintenance of the front and rear motors is relatively simple.


Price


The cost of the mid-mounted motor is usually higher, and the vehicle price is correspondingly higher.


The cost of the front and rear motors is lower, and the vehicle price is relatively affordable.


Influence on the frame


The mid-mounted motor has higher requirements for the strength of the frame, and the frame needs to have a better structural design.


The requirements of the front and rear motors on the frame are relatively low.
