The ideal drive for every application

Part of the success of FLYER e-bikes can be attributed to its partner Bosch. Our product developers are always in touch with the specialists at Bosch, keeping their finger on the pulse of the latest technological innovations. This is an important prerequisite for making e-bikes even smarter than they are today.

The company’s products and digital services are installed on FLYER e-bikes, ranging from highly efficient drive systems and the first series-ready ABS for e-bikes to connected biking solutions.

2. Motors (drive units)

The motor (also referred to as the drive unit by Bosch) and battery are the heart of an e-bike.

3. Bosch eBike batteries

Our e-bikes are equipped with high-performance batteries. They contain cell types specially developed for use with e-bikes. They boast a perfect balance between capacity, performance, weight and lifetime. The special feature of lithium-ion batteries is their particularly high energy density. The high energy density ensures that the batteries can store more energy with a relatively low net weight.


Bosch batteries are an efficient and long-lasting source of energy – and are among the most modern e-bike batteries on the market. They combine enormous mileage, a long lifetime and low weight with ergonomic design and easy handling. The high-quality lithium-ion batteries are equipped with a battery management system that detects potential sources of error and protects the battery cells from overloading. 

Characteristics of Bosch e-bike batteries

  • Bosch batteries have a low weight in relation to their energy content
  • Sophisticated waterproofing concept to protect against the ingress of water
  • Minimal self-discharge, even when not used during the winter months
  • High-quality lithium-ion cells

Bosch PowerTube 500 | 625 | 750 Wh


The Bosch PowerTube batteries are fully integrated into the frame to ensure a clean look. The batteries are easy to remove and can also be charged directly on the e-bike.


Bosch PowerTube batteries guarantee you the right amount of energy storage for demanding tours: For long journeys through challenging terrain, we recommend the Bosch PowerTube 750. For shorter tours on flat roads, we recommend a Bosch PowerTube 500. 750 and 500 each stand for the number of Wh the battery has.

4. Displays

5. Control units

The Remote is the intelligent control unit of an e-bike. It connects the e-bike to the eBike Flow app and provides access to numerous e-bike functions. This makes it easy to retrieve all important riding data – while keeping your hands securely on the handlebars. Change the riding modes, use the pushing aid and operate the display or ride screen on your smartphone. Great importance is attached to comfort, flexibility and security.

  • Intuitive control
  • Compact design
  • Easy to use

The LED displays on the Remote can be easily seen even in sunlight. The brightness of the display adapts flexibly to the ambient light. This ensures that it remains easy to read even in changing lighting conditions and does not dazzle you in the dark. The different LED colors indicate the selected riding mode.


6. Bosch E-Bike ABS


Safety comes first

  • Greater safety
  • More riding fun
  • More flow

A new feature Bosch has introduced is the Bosch eBike ABS. ABS is already used in our latest touring model, the Gotour. The small, unobtrusive brake assistant fits nicely into the e-bike design and helps you brake more effectively and safely without the wheels locking. Just like it does on your car.


But how does Bosch eBike ABS actually work?

Wheel speed sensors monitor the speed of the wheels. If the wheel is at risk of locking during hard braking, the ABS regulates the brake pressure and prevents the wheel from slipping away. The coordinated and sensitively regulated braking behavior provides significantly more control and stability. Whether on asphalt or slippery gravel roads, the Bosch eBike ABS lets you brake more safely and confidently with both brakes at the same time.
