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.<\/p>\n
Design and Frame<\/strong><\/p>\n 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.<\/p>\n Carbon Frame and Battery Integration<\/strong><\/p>\n 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.<\/p>\n Geometry and Sizing<\/strong><\/p>\n 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\u201d rear wheel, while sizes M\/L and larger adopt a full 29\u201d wheel configuration. Reach measurements span from 425 mm in size S to 520 mm in size XL, accommodating a wide range of rider preferences.<\/p>\n Componentry and Pricing<\/strong><\/p>\n 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 \u20ac8,490 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 \u20ac9,990, 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 \u20ac11,990, 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 \u20ac13,490, features SRAM XX-series components, the Ultimate version of the MOTIVE brakes with carbon levers, and an exclusive Lava Orange paint finish.<\/p>\n Conclusion<\/strong><\/p>\n 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.<\/p>\n For more information, visit ROTWILD’s official website.<\/p>\n
