New Frame

The new frame shape impresses with an extremely low center of gravity and increased rigidity, thereby enabling more agile behavior for even more riding pleasure. In addition, a range extender is now optionally available for all frame sizes S-XL.

Would you like to ride longer tours or climb higher mountains? Not a problem with the Haibike Range Extender Option. Elegantly integrated on the down tube, the optional Haibike Range Extender offers an additional 500 Wh of battery power. Now available for all Bosch Performance CX Gen 4 models in frame sizes S-XL.


If you look at the history of the integration of Bosch eBike systems over the past 10 years in detail at Haibike, you can clearly see the further development of design and design language. But what are the main reasons for the new Bosch Gen 4 frame design that clearly stands out from its predecessors? “Our goal was to continue the successful Haibike rear-link kinematics and at the same time to enable the integration of a range extender for all frame sizes. In addition, this type of construction leads to a lower center of mass and thus underlines our claim to ePerformance ", says Hendrik Schäfers, Head of Innovation Design / HDCM.

use of energy

Optimum and improved efficiency of motor and gearbox in order to conquer long, steep climbs.
The smaller Bosch Gen 4 motor allowed our designers to create a bike with shorter chainstays, and therefore increased maneuverability and playfulness. The reduced pedling resistance allows for more efficient riding and a more natural riding sensation.
