Tip: Think about how you want to use your e-bike. Do you want to cruise relaxed through the city or conquer steep climbs? The choice of motor determines comfort, maintenance, and riding pleasure.

E-bike motor: Power & Torque

Meaning of watts and Newton meters

You have surely heard of watts and Newton meters when dealing with e-bikes. These terms determine how strongly your e-bike motor supports you and how the riding feels. Watt measures the power of the motor. In Europe, a pedelec may have a maximum of 250 watts. That is enough for most everyday rides.

Newton meters show you the torque. This is the force you feel when pedaling. The more Newton meters, the more powerfully the motor pushes you forward. You will notice the difference especially when starting up or on steep hills. A high value, for example 50 to 85 Newton meters, makes riding on challenging terrain much easier.

Here you can see how watts and Newton meters influence the riding feel:

  • Watt indicates how much energy the e-bike motor can deliver.

  • Newton meters provide the "boost" you need when starting off or on inclines.

  • With more torque, every incline feels flatter.

  • Your cadence influences how much support you get. At a low cadence and high force, you need maximum torque.

Tip: If you often start at traffic lights or ride in hilly regions, pay particular attention to the torque of your e-bike motor.

Appropriate power for different purposes

Are you wondering how much power your e-bike motor should have? That depends on where and how you want to ride. For the city, you need less power than in the mountains. Here you will find an overview of the recommended power for different e-bike types:

E-bike type

Recommended motor power (Nm)

E-city bike

40–50

E-trekking bike

40–60

E-mountain bike

60–80

If you ride an urban pedelec, 40 to 50 Newton meters are sufficient. That provides pleasant support for everyday life. For commuters who cover longer distances or handle slight hills, 40 to 60 Newton meters are ideal. Are you planning off-road tours or do you want to conquer steep mountains? You will need at least 60 Newton meters. This way you will always have enough power, even when it gets really steep.

Many commuters choose a mid-drive motor because it works efficiently and provides even support. A battery with a 60 to 80 kilometer range gives you security, even if you have to take a detour. For daily use, fenders, a luggage rack, and lights are practical. You can choose between hub gears and derailleur gears – one is low-maintenance, the other is efficient for long distances.

Note: Think about how you want to use your e-bike. The more inclines and challenging paths you ride, the more important a high torque value is for the e-bike motor. For the city, less is often enough, but for off-road use, you need more power.

As you can see: The right combination of power and torque makes the difference. With the right e-bike motor, you enjoy riding pleasure and feel safe – whether in everyday life or on adventure tours.
