MAHLE SmartBike Systems unveiled the new XS System, offering freedom in bicycle design. The XS system simplifies eBike integration by eliminating the need for a large internal battery, instead utilizing the compact eX1 external battery as the exclusive energy source.

Paired with MAHLE X20 or X30 motors, the system weighs just 2.5 kilograms with the X20, generating as much torque as a 55 N·m mid-drive. The XS System is compatible with the full MAHLE Ecosystem and is already available in the market.

Battery integration has long posed a challenge for bike manufacturers due to size and assembly complexities. MAHLE’s XS system solves this by offering a streamlined eBike setup powered entirely by a 1kg external battery, which conveniently fits in a standard water bottle cage. In addition, the newly developed Smart Motor Controller can be mounted inside or outside the frame, allowing for minimalistic, unobtrusive integration—making it possible to use standard muscular bike frames to create fully functional eBikes.

Without sacrificing performance, the XS system comprises only the essential components: the eX1 External Battery, XS Smart Controller, X20 or X30 Hub Drive Unit, and a Torque or PAS (Pedal Assist) Sensor. This minimalism reduces the system’s environmental footprint by downsizing components and simplifying the system’s architecture. Furthermore, its ease of maintenance and broad range of accessories provide limitless customization opportunities.

The eX1 battery fits perfectly for daily use, offering more than 170Wh of capacity.

In our research, we found that even less than 100Wh are sufficient for most daily activities—urban commuting, short rides—so we focused on optimizing for what riders need. The result is XS: a light, efficient system that perfectly suits everyday use.

Additionally, the eX1 battery serves as a Range Extender for any existing MAHLE X20 or X30 system and as a power bank to charge devices such as phones or laptops thanks to a USB-C port integrated in the Energy Hub charger, which comes along with the system.

The XS system also integrates with the expansive X-series accessory line, enhancing both performance and user experience. Customization is nearly limitless, with optional accessories such as the Duo, eShifters, and Pulsar ONE, among others, available for added functionality.

Users can also connect to the MAHLE Digital Ecosystem via their eBike, laptop, smartphone, or Apple Watch, opening the door to the present and future of the smartbike revolution. The MAHLE digital ecosystem enables a multitude of functionalities.

Using the system is very intuitive. With an intuitive control, riders can power on the system, switch between assistance modes, and monitor battery levels directly from the interface atop the eX1 External Battery. The system also offers automatic assistance, enhancing ease of use.
