1. Bearing capacity of front shock absorber

In front drive e-bike conversion kit, the power can only be transmitted to the car body through two shock absorbers, and the transmission arm is very long, which leads to a large shear force on the shock absorber. Then your shock absorber should be strong enough and durable enough. The rear drive e-bike conversion kit is directly connected to the frame, and is forced by the frame when driving.

2. Driving efficiency

Whether it is an electric vehicle or a motorcycle, the center of gravity of the vehicle moves backward when accelerating, and the adhesion of the rear wheels is greater at this time. When the motor power is high, the rear drive is not easy to slip, so the driving efficiency is higher. I once rode a front drive e-bike conversion kit, which is a tricycle for the elderly. When turning on the cement road, it is obvious that the front wheels slip slightly, and the driving force is wasted.

3. The front drive e-bike conversion kit direction changes frequently, which is not as stable as the rear wheel

The front wheels are responsible for turning. If the front wheels drive, the direction of the driving force will change when you turn. The driving force of the rear wheel is consistent with that of the vehicle body, which is more stable.

4. The adhesion of the rear wheel is better

When two wheeled vehicles turn or change lanes, the body will roll, and when the front wheels turn, they will also deflect a certain angle, so when they turn, the rear wheels have a larger landing area and greater adhesion to the ground.

For example, in the car above, it's easy for electric vehicles to encounter this attitude, and the adhesion state of the front wheels is obviously not as good as that of the rear wheels.

The low energy consumption of the precursor is relative to the automobile

Because the vast majority of automobile engines and transmissions are located in the front of the car, the use of the front drive structure does not require too complex transmission system, the transmission directly outputs two transmission half shafts to transmit power to the driving wheels. Then driving needs to use the transmission shaft to transmit the power to the rear axle first, and then to the two driving wheels through the differential and the transmission half shaft. Obviously, the more complex rear drive structure and more operating components of the system will definitely increase the operating resistance, resulting in higher fuel consumption. The wheels of electric vehicles are electric motors, which will not increase the resistance of the transmission system whether they are installed in the front or the back.

Because most of our electric vehicles are high-power motors, and the daily use frequency is high, the use conditions are relatively strict, so the rear drive is definitely the best choice.
