13,490 euros for an e-trail bike? That’s quite a statement, even in the premium segment. After all, Rotwild is offering the full works: Fox Factory, SRAM XX AXS, carbon wheels and 1,500-watt Avinox power. Pimping, tuning, retrofitting – At least with the Rotwild R.XX Ultimate, you don’t have to worry about that.
Rotwild had already unveiled the R.XX to the global public this summer. In a nutshell: with this model, Rotwild aims to deliver maximum motor power whilst keeping the weight to a minimum. This lightweight e-mountain bike is designed to impress with its agile handling and high level of riding enjoyment. 160 millimetres of front suspension travel and 150 millimetres at the rear provide plenty of headroom for technical descents – but the focus is on minimal weight and active, playful handling. The specially tuned Elevated Box kinematics are designed to provide direct feedback from the terrain and encourage riders to actively engage with the trail.
The Polydynamic Carbon frame houses the 700 Wh battery, which is fully integrated into the down tube. In sizes S and M, the R.XX is a mullet bike with a 29-inch front wheel and a 27.5-inch rear wheel. From size M/L upwards, Rotwild opts for two 29-inch wheels. Five frame sizes, adjustable chainstays and a long reach are designed to ensure a balanced riding position and smooth handling across all sizes.
So, here’s the Ultimate. Naturally, it comes with the incredibly powerful Avinox M2.S, delivering up to 150 Newton-metres of torque and 1,500 watts, a 12-amp charger and the super-slim 700 Wh battery. Rotwild hasn’t yet specified a weight for the Ultimate, but earlier statements mentioned a figure of 20 kilos.
As befits its price tag, the R.XX Ultimate struts its stuff on the trail with only the very finest components: a Fox 36 Float Factory Kashima with Grip-X damping, a Fox Float X Factory Kashima, an SRAM XX Eagle AXS drivetrain and SRAM Motive Ultimate carbon brakes. The package is rounded off with Newmen Phase carbon wheels, carbon cranks from ethirteen, an 8Pins dropper post and Rotwild’s own B220 carbon handlebars. The Lava Orange frame colour is reserved exclusively for the Ultimate.
