City and Daily Use

Do you often ride short distances, run errands, or commute to work? Then you need an e-bike that is light and uncomplicated. In the city, a front-hub motor is often enough. It is inexpensive and easy to operate. It fits well for flat paths and light luggage. A mid-drive motor brings you more comfort if you encounter many traffic lights or have to start pedaling frequently. It supports you evenly and makes the bike agile. A rear-hub motor is suitable if you prefer a sportier ride and like a dynamic riding feel.

Tip: Consider how often you need to carry or push your bike. A lighter motor helps in everyday life.

Tours and Long Distances

Are you planning longer excursions or want to discover new paths on the weekend? Then you need a motor that supports you reliably. Many trekking fans swear by mid-drive motors. They offer you natural support and help you save energy. Rear-hub motors are also an option for relaxed tours if you like a sporty feel.

Here you can see a comparison of popular motors for long distances:

Note: For long tours, not only motor power counts, but also battery capacity.

Mountains and Steep Terrain

Do you live in hilly terrain or often want to go into the mountains? Then you need a motor with high torque. Mid-drive motors are the best choice here. They deliver the power you need for steep climbs. Values between 70 and 85 Nm are ideal. For extreme inclines, you even need more than 100 Nm. This way, you can make good progress even under difficult conditions.

  • Mid-drive motors offer the highest torque.

  • Hub motors (front and rear) lose efficiency at low speeds.

  • During slow riding, a hub motor can overheat and waste energy.

A high cadence between 75 and 90 revolutions per minute helps you use the motor efficiently. This keeps you relaxed even on long climbs.

Tip: It is best to test your e-bike on the terrain you ride most often. This will help you quickly determine which motor suits you.

Technical Characteristics of the E-bike Motor

Performance – Wattage and Power

The motor power determines how much assistance you get while riding. In Germany, an e-bike motor may have a maximum output of 250 watts for your bike to be classified as a bicycle. This allows you to ride safely in traffic without needing a driver's license. The wattage indicates how strongly the motor pushes. However, more watts do not always mean more speed, but rather more support when starting and climbing.

Take a look at the differences in motors and batteries in various price ranges:

Price range

Motor

Battery

€800–1,500 (Entry-level)

Bafang, Ananda, No-name

360–460 Wh

€1,500–3,000 (Mid-range)

Bosch, Shimano, Brose

500–625 Wh

€3,000–5,000 (High-end)

Bosch CX, Shimano EP8

625–750 Wh

€5,000+ (Premium)

TQ, Fazua, Bosch CX Race

350–750 Wh

Tip: For everyday use, a 250-watt motor is often sufficient. For steep mountains or heavy loads, it is worth checking the battery capacity.

Torque – Meaning and Recommendation

Torque shows how much force the motor applies to the pedals. It is measured in Newton meters (Nm). Higher torque helps you especially when starting and on inclines. For most routes, a torque of 60 to 85 Nm is sufficient. If you often ride in the mountains or with heavy luggage, you should look for a motor with at least 70 Nm.

Strong torque provides a powerful riding feel. You get ahead more easily, even when it gets steep. For relaxed rides in the city, a lower value is often enough.

Sensors – Torque Sensors in Comparison

Sensors control how the motor reacts to your movement. There are two main types: torque sensors and cadence sensors. Both significantly influence the riding feel.

Sensor type

Functionality

Riding feel

Torque sensor

Measures the force you apply to the pedals and adjusts the assistance accordingly.

Natural and harmonious riding feel.

Cadence sensor

Measures how fast you are pedaling and controls motor output.

Increases efficiency and is gentle on the joints.

With a torque sensor, the riding experience feels particularly natural. The motor provides support exactly when you need more power. A cadence sensor helps you pedal consistently and saves energy.

Weight and noise levels

The weight of the motor plays a major role in handling. A heavier motor makes the bike heavier overall, which increases energy consumption. If you are carrying extra luggage or a child, your range will decrease. For every five kilos of extra weight, the range drops by approximately 2.5 kilometers.

The noise level of the motor is also important. Many recreational riders want the motor to be as quiet as possible. Manufacturers invest heavily in quiet drive systems so that you can ride in a relaxed manner.

  • A heavy motor increases the total load.

  • More weight means higher energy consumption.

  • Noise levels influence the riding experience and the purchasing decision.

Note: Test how loud the motor actually is before buying. What sounds quiet in the shop might sound different on the road.

Maintenance and lifespan

An e-bike motor will last for many years with good care. Most manufacturers recommend an annual inspection. Some experts even advise having it checked every 500 kilometers to keep your motor reliable and safe.

  • Have your bike serviced once a year.

  • If you use it heavily, an inspection every 500 kilometers is recommended.

Maintenance costs vary depending on the motor type. Mid-drive motors in particular require more frequent chain and sprocket changes. This costs between 80 and 200 euros. With good care, replacing them every 2,000 to 4,000 kilometers is sufficient. A rear hub motor makes changing the rear wheel slightly more complicated, but wear and tear is often lower.

Tip: Pay attention to regular maintenance. This will extend the life of your motor and you will enjoy your e-bike for longer.

Individual needs and route profile

Riding style and comfort

Your riding style determines which motor suits you best. Do you ride in a relaxed way through the city, or do you love sporty tours? Depending on how you ride, you will need more or less support. Many users say that the route profile and the length of the trips play a major role. For flat paths, a motor with less torque is often sufficient. In mountainous regions or when carrying heavy loads, you will need more power.

Here you can see which motors are recommended for different types of routes:
