With the R.XX, Rotwild has launched a new e-mountain bike for the 2027 model year that isn’t just meant to be powered by its motor on uphill climbs. The focus is on agile and responsive handling on challenging trails. Fast turns, technical sections, and an active riding style are where the R.XX truly shines.

The bike is built around a handcrafted carbon frame with a fully integrated battery offering a capacity of 700 watt-hours. For the rear triangle, Rotwild relies on its Elevated-Box construction and a deliberately lively kinematic design. The geometry is also worth noting: The R.XX is available in five frame sizes, with the length of the rear triangle increasing as the frame size grows. This is intended to keep the weight distribution as balanced as possible across the entire size range.

The Avinox M2.S provides assistance on climbs. The compact motor, together with the integrated Avinox battery, is housed in the R.XX and forms the drive system of the new bike.

Ultimate Takes the Lead

Until now, the R.XX lineup ended with the Ultra trim level. Now Rotwild is taking it a step further and expanding the series to include the R.XX Ultimate. This means there will be four variants to choose from in the future: Core, Pro, Ultra, and Ultimate.

No expense has been spared on the new top-of-the-line model. SRAM contributes the XX Eagle drivetrain, while braking is handled by Motive Ultimate Carbon brakes. The suspension comes from Fox: up front is a 36 Float Factory with Kashima coating, while a Float X Factory Kashima handles damping at the rear. Rotwild also equips the Ultimate with a set of Newmen Phase Carbon wheels.

Visually, too, the top model is allowed to make a bolder statement. While the technology is tuned for maximum performance, the “Lava Orange” paint job ensures that the most expensive version stands out from the R.XX family at first glance.

Production of the new Rotwild R.XX will begin in January 2027.
