Mahle introduce XS System powered solely by external battery

Mahle has unveiled its new XS System, aimed at eliminating the need for a large internal battery, with the eX1 external Range Extender battery as its exclusive energy source.

The eX1 battery, which already serves as a Range Extender for any existing Mahle X20 or X30 system, offers over 170Wh of capacity and “enables the XS system to simplify e-bike integration – eliminating the need for a large internal battery.”

Utilizing the compact eX1 external battery as the energy source, the system weighs in at 2.5 kg, when using the X20, whilst generating as much torque as a 55 Nm mid-drive.

Commenting on the capacity, Marco de la Serna, head of product, strategy, and business development at Mahle SmartBike Systems, notes: “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.”

EX1 as an auxiliary power source

The eX1 is compatible with both X20 and X30 motors, and, in addition to powering the X20 and X30 motor units, can also function as a power bank to charge devices such as phones or laptops, thanks to a USB-C port integrated into the Energy Hub charger, which comes along with the system.

Turning any bike into an e-bike

Battery integration poses a challenge for bike manufacturers, due to size and assembly complexities. With the XS System, Mahle presents a significant alternative, offering a streamlined setup, powered entirely by a 1kg external battery, which fits in a standard water bottle cage.

In addition, the newly developed Smart Motor Controller can be mounted inside or outside the frame – making it possible to use standard bike frames to create fully functional e-bikes.

At launch, Jochen Sommer, general manager of Mahle SmartBike Systems, comments: “Our passion for innovation and commitment to cyclists inspire us to continually push boundaries. With the XS system, we have distilled the e-bike down to its most essential elements, delivering unmatched value.”

The XS System is comprised of 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.

A company spokesperson further highlights “this approach reduces the system’s environmental footprint by downsizing components and simplifying the system’s architecture. Furthermore, its ease of maintenance and a broad range of accessories provide limitless customization opportunities.”

The XS System is compatible with the full Mahle Ecosystem and is already available in the market, integrating into the X-series accessory line, enhancing both performance and user experience.

Customization options include accessories like the Duo, eShifters, and Pulsar ONE, among others, all offering added functionality.

Smart device connectivity

Users can also connect to the Mahle Digital Ecosystem via their e-bike, laptop, smartphone, or Apple Watch, opening the door to the present and future development and user experience enhancements.
