Comparison of mid-drive motor & hub motor

Power & assistance

Do you want to know how mid-drive motors and hub motors differ in performance? Mid-drive motors offer you more power and stronger support, especially when you choose the highest assistance level. This is particularly noticeable when starting off and on steep routes. Hub motors usually do not reach the same power as mid-drive motors. They often have to be calculated differently to enable a fair comparison.

• Mid-drive motors offer you better power in the highest assistance level.

• Hub motors are sufficient for flat routes and moderate speeds.

If you often ride uphill or are a sporty rider, you benefit from a mid-drive motor. The range also depends on the battery. Mid-drive motors usually have larger batteries, which increases the range. However, the higher weight can reduce the range again.

1. Mid-drive motors offer higher torque, which improves their performance in practice.

2. They generally have larger batteries, which theoretically increases the range.

3. The higher total weight of mid-drive motors can, however, negatively affect the range.

Riding behavior & center of gravity

The riding behavior of an e-bike depends heavily on the motor position. A mid-drive motor sits centrally and low in the frame. This lowers the center of gravity and ensures a stable, neutral riding feel. You feel safe, even at high speeds or in corners. Especially with luggage, the bike remains easy to control.

“The central mounting also lowers the center of gravity, which has a positive effect on the riding behavior, especially when riding sporty e-(mountain) bikes.”

• The mounting point of the motor at the bottom bracket ensures a low and central center of gravity. This has a positive effect on the handling of the pedelec.

The center of gravity is central and low, which ensures good handling. Hub motors are usually located in the rear wheel. This ensures a rear-heavy weight distribution. You get good traction on steep gravel passages uphill, but the handling is less balanced.

Maintenance & costs

Do you want to know how much time and money you should budget for maintenance and spare parts? Hub motors are considered lower-maintenance. You usually only have to take care of plug connections and cables. The maintenance costs remain low. Mid-drive motors put more strain on the chain and cassette. You have to change these parts more often, which increases the costs.

• Hub motors are often replaced completely when a defect occurs, instead of repairing them.

• It is important to choose a manufacturer or dealer who supplies spare parts even years after purchase.

• Mid-drive motors have higher wear costs due to the load on the chain and drive components.

If you are looking for an e-bike for everyday use and have little time for maintenance, a hub motor is often the better choice.
