Bosch Performance Line Speed – Powerful drive unit for S-pedelecs

- 85 Nm: maximum torque for powerful acceleration and confident assistance
- 600 W: maximum motor power for dynamic riding at speeds of up to 45 km/h
- 340 %: maximum assistance for effortless progress even on inclines
- 2.9 kg: low motor weight for balanced and agile handling
Carefree riding
Thanks to intelligent sensor technology, the Performance Line Speed responds with exceptional precision to every pedal stroke. This ensures direct power transmission, a natural riding feel and maximum control – even at high speeds.
Precise speed detection
The Performance Line Speed is fitted with a wired speed sensor, including a spoke or brake disc magnet, or alternatively with a wireless speed sensor and rim magnet. This ensures reliable and accurate measurement of riding speed.
Bosch eBike ABS for greater safety
The Drive Unit’s sensors work in conjunction with Bosch eBike ABS to support controlled braking performance. The system increases stability and improves control during emergency braking, at junctions, on pedestrian crossings or on slippery surfaces.
Automatic assistance in Auto mode
The intelligent Auto Mode automatically adjusts motor assistance to changing conditions such as inclines or strong headwinds. This ensures a comfortable, efficient and smooth riding experience.
Further advantages
Compact design
The compact design and lightweight magnesium housing reduce the weight of the Bosch Performance Line Speed Drive Unit to just 2.9 kg. This ensures balanced handling and makes the e-bike easier to control.
Push and hill-start assist
The integrated push assist makes it easier to push the e-bike up steep inclines. The hill-start assist prevents the bike from rolling backwards unintentionally when setting off, ensuring greater safety and comfort on inclines.
Limit mode for greater range
In Limit mode, the Speed-Pedelec provides assistance up to a speed of 25 km/h. This reduces energy consumption, increases range and allows for relaxed riding in groups at a constant speed.
Automatic optimal assistance up to 25 km/h: for S-pedelecs
- Automatic adjustment of motor assistance, providing up to 340 per cent of the rider’s own effort up to a speed of 25 km/h
- Energy-efficient riding in urban traffic and comfortable group riding thanks to the adapted assistance level
- Exclusively available for S-pedelecs in the EU fitted with the Bosch Performance Line Speed drive
- Legal requirements such as compulsory helmet use, number plate registration and insurance, as well as existing riding restrictions – for example on cycle paths – remain in force
Further features

Digital security features protect the eBike against theft. With eBike Lock, eBike Alarm and Battery Lock, practical solutions are available for greater security and reliable theft protection.
Navigating with range
The detailed map view on the display ensures better orientation and supports precise route guidance, including a range indicator.
Perfectly tailored riding modes
Assistance, dynamics, speed and torque can be individually adjusted via the eBike Flow app. Four preferred riding modes can be saved and used at any time.
CO₂ savings at a glance
After every ride, the eBike Flow app shows how much CO₂ has been saved compared to a car journey over the same route.
Current battery level available at any time
The battery charge level can be checked at any time in the eBike Flow app. This means you can see when the battery is fully charged before your next ride.
Always up to date
Regular software updates expand the range of functions and keep the eBike system up to date. New features can be conveniently downloaded and transferred to the eBike via Bluetooth.
