Electric Bike's Motor Comparison

Electric Bike’s Motor Comparison: Front Hub vs. Rear Hub vs. Mid-drive

Front Hub Wheel Motor

Advantages: a motor in the front wheel is technically the simplest. The electric bike’s frame is very similar to that of a normal bike since the chain and gear unit do not have to be taken into account. In more than half of the cheaper bicycles tested, the motor is in that position.

Disadvantages: The engine’s pulling power must be limited to prevent the front wheel from slipping, especially on slopes and on wet roads. Given the position of the cyclist and any luggage, the weight of the bike mainly rests on the rear wheel. As a result, you have to make a large part of the effort yourself on steep slopes. This model is therefore recommended if you do not want to brave too steep slopes.

Rear Hub Wheel Motor

Advantages: With a motor in the rear wheel, the risk of skidding is practically excluded, even with high power. The load on the chain and gear unit is also less than with a mid-motor bike.

Disadvantages: The gear system does not work equally effectively in all conditions. On strong slopes, you still have to make a lot of effort.

Mid-drive Motor

Advantages: the bottom bracket is part of the motor system. The efforts of both the e-bike and the cyclist are transferred to the rear wheel via the chain. So even on the steepest slopes, the motor provides maximum assistance. Moreover, a flat tire at the front or rear is no more difficult to repair than with a normal bike. After all, you can disassemble both wheels without the help of the electric bike manufacturer or special tools.

Disadvantage: the chain and gearing devices wear faster because they have to transfer the effort from the motorbike and cyclist to the rear wheel.
