ROTWILD has unveiled the R.XX, a lightweight performance e-mountain bike (eMTB) featuring the innovative Avinox M2S motor system. Weighing approximately 20 kg, the R.XX boasts a 700 Wh battery and delivers up to 1,500 W of peak power, promising an exciting blend of power and agility.
Design and Frame
The R.XX’s design aligns with ROTWILD’s current aesthetic while introducing unique elements. The frame incorporates characteristic seat stays and a mid-high main pivot, reminiscent of the R.EX and R.EXC models but with a more refined appearance. Notably, the FOX Float X shock is integrated horizontally within the main frame, encased by a distinctive cut-out in the top tube, enhancing both aesthetics and functionality.
Carbon Frame and Battery Integration
A highlight of the R.XX is its Polydynamic Carbon frame, constructed with high-quality 1,100 UD carbon fibers to achieve an optimal balance between weight and stiffness. Departing from previous models, the R.XX features a fixed 700 Wh battery with round cell technology, eliminating the need for a removable battery compartment. This design choice not only reduces weight but also increases frame rigidity. The integrated battery design allows for a closed downtube, providing a cleaner look and improved structural integrity.
Geometry and Sizing
The R.XX introduces a new geometry with sizes S, M, L, XL, and an additional M/L size. Chainstay lengths range from 435 mm to 460 mm, scaling proportionally with frame size to ensure balanced handling across all models. Smaller sizes (S and M) feature a mullet wheel setup with a 27.5” rear wheel, while sizes M/L and larger adopt a full 29” wheel configuration. Reach measurements span from 425 mm in size S to 520 mm in size XL, accommodating a wide range of rider preferences.
Componentry and Pricing
The R.XX is available in four configurations, each equipped with FOX suspension components, SRAM drivetrain and braking systems, Schwalbe tires, and an Eightpins dropper post. The entry-level R.XX CORE is priced at €8,490 and features the Avinox M2 Drive Unit with 1,100 W peak power and 125 Nm torque in Boost mode. It includes a FOX 36 Rhythm fork with a GRIP cartridge and a mechanical SRAM EAGLE 90 transmission. The R.XX PRO, at €9,990, upgrades to the Avinox M2S Drive Unit, an electronic SRAM GX Transmission derailleur, lightweight Newmen Carbon wheels, and a FOX 36 Performance fork. The R.XX ULTRA, priced at €11,990, offers a FOX 36 Factory fork and a Fox Float shock, both with Kashima coating, along with SRAM X0-series components and Silver-model MOTIVE brakes. The top-tier R.XX ULTIMATE, at €13,490, features SRAM XX-series components, the Ultimate version of the MOTIVE brakes with carbon levers, and an exclusive Lava Orange paint finish.
Conclusion
With the R.XX, ROTWILD expands its lineup, filling the gap between the downhill-focused R.EX and R.EXC models. The R.XX aims to deliver a combination of lightness, responsiveness, and flow on challenging trails. Initial impressions suggest it holds promise, but real-world testing will be essential to confirm its performance.
