The battery capacity plays a decisive role in the range of your e-bike. Bosch offers powerful batteries like the PowerTube 750, which enables an impressive range. The combination of a strong motor and a high-quality battery ensures an optimal riding experience.

The table shows that you can achieve a high range with a Bosch battery, even on demanding rides. However, the actual range depends on various factors that you can influence.

Influence of riding style

Your riding style has a major influence on the range of your e-bike. Various factors play a role here:

• Support levels

• Riding behavior

• Air resistance

• Rider weight

• Tire pressure

• Terrain

• Surface conditions

• Inclines and gradients

A high support mode or steep climbs require more energy and reduce the range. Uneven surfaces increase rolling resistance, which also reduces the range. On average, you can cover between 80 and 100 kilometers with a modern e-bike battery. The more the motor has to work, the faster the battery level drops.

Tips for battery life

With a few simple measures, you can extend the battery life of your e-bike:

1. Choose the right support mode: Use the Eco mode for flat routes and only switch to higher modes when necessary.

2. Pay attention to tire pressure: Optimal tire pressure reduces rolling resistance and saves energy.

3. Plan your route: Avoid unnecessary climbs and choose the flattest routes possible.

4. Maintain the battery: Charge it regularly and store it at moderate temperatures.

5. Ride with foresight: Avoid abrupt acceleration and maintain a consistent speed.

Tip: With these measures, you can not only maximize the range of your battery but also extend its service life. A well-maintained battery ensures more riding pleasure and reliability.

Bosch offers you an impressive selection of e-bike motors optimized for every area of application. Whether you are commuting in the city, riding sportily, or planning challenging off-road rides – you will always find the right motor.
