Bosch eBike Systems
Developed for limitless fun, eBikes with components from Bosch eBike Systems deliver outstanding technical quality and work as a perfectly coordinated team. The smart system from Bosch eBike Systems – consisting of the eBike Flow app, control unit, display, battery, and drive unit – ensures a very personal eBike experience. The new system generation combines technically high-quality eBike components with digital functions, taking fun to the next level, whether in everyday use or for pleasure.
Around 90% of all electric bikes have a mid-drive motor. Most eBike riders have good reason to choose this concept:
The advanced drive technology provides a natural riding sensation thanks to the direct transfer of power to the chain. Compared with front or rear wheel motors, the mid-drive motor offers a balanced weight distribution and center of gravity. It also offers excellent drive control, is compatible with all gear shifting systems, and requires less energy thanks to better efficiency. Another advantage of the mid-drive motor is its compact, low-weight design. It integrates perfectly into the frame design, providing more ground clearance and a lower Q factor.
Whether you’re buying an eBike to drive a car less, spend more time outdoors with your family, or to hit your favorite trail, Bosch has a system that will fit your riding style.



What is an eBike system?
The electric drive of the eBike, the display and matching control unit, and the battery are the components that make up an electric bike. They are supplemented by digital services and apps. In a system, all components communicate with each other and adjust to your particular riding situation. So you ride more efficiently, more comfortably and have an incredible time doing so!
Which Bosch eBike systems are available?
With Bosch eBike systems you have the choice between two systems – you can find out what advantages they offer and which one suits you best here.

This way, your eBike remains up to date even after purchase and continues to evolve.

The ideal drive for every application



Controlled or powerful support – the main thing is it feels natural. Drive units from Bosch eBike Systems are pedal-assist, Class 1 (up to 20mph), and Class 3 (up to 28mph), which means that the drive unit amplifies your pedal power. Three sensors measure pedal power, cadence, and speed at a rate of over 1,000 times per second. This enables organic interaction between you and your eBike. The drive unit of the smart system, the new system generation of Bosch eBike Systems, also ensures a very personal eBike experience. The smart system combines high-quality eBike components with digital functions, is fully connected, and is always up to date thanks to over-the-air updates.
The best battery for your ride



Bosch eBike rechargeable batteries are an efficient, long-lasting power source. Featuring an extended range, long service life, and an intelligent Battery Management System (BMS), Bosch lithium-ion batteries are among the most technologically advanced on the market. In addition, they are lightweight, ergonomic, and easy to recharge and install. The Battery Management System that comes with these high-quality lithium-ion batteries detects potential error sources and protects cells from overheating. Bosch has the perfect rechargeable battery model for every type of eBike, from rack batteries to frame batteries as well as integrated solutions. The Bosch DualBattery solution, for example, is perfect for Hybrid eBikes, long-distance commuter eBikes, or cargo eBikes, delivering up to 1,250 Watt-hours.
Full support on the handlebar



Bosch eBike displays are the ideal companion for every situation – from the purist control unit and the all-in-one computer to the smartphone solution on the handlebar. To make it easier to compare the different displays and choose the one that best suits your needs, distinguishing between connected and non-connected displays is a good place to start.
