Every system requires powerful and reliable propulsion! The HESC ATS front wheel drive system is the heart of our system!

The HESC ATS Front motor is the choice for front-wheel-drive city bikes. Suitable for getting around the often narrow city streets, the 40 Nm torque and 250 W (max. 400 W) offer a powerful, but easy-to-control system, thanks to ATS Sensor technology, for your everyday requirements.

The front-wheel system reduces the physical wear and tear of cranks, cassettes and chains and their associated costs.

Torque sensor

Pedalling frequenzy sensor

Infrared measurement: 36 measuring points

Chainwheel size: 38 teeth


You ride, we measure. The pedalling frequency and pedalling power parameter is determined via infrared.

You have a decisive influence on the driving properties, which we want to make as natural and dynamic as possible. You decide on the characteristics by choosing the assistance mode and the way and manner in which you turn the pedals.

Adapted to specific requirements, our city bikes have a crank with 38 teeth; mountain bikes and sporty trekking bikes have 42 teeth and an additional chain ring guard.


Capacity: 8,6 Ah, 11.6Ah

Range: up to 100km

Charging time: 4-5 hours

Charging cycles with guaranteed residual capacity: 500

Charging options: in installed or uninstalled position



The battery supplies the system with the energy it needs. For sport-orientated bikes we have developed a 11.6Ah version for longer and more challenging rides. This means a range of up to 100 km and a charging time of 4 to 5 hours, depending on the way it is ridden and other conditions. It can be charged in the installed or uninstalled position.
