appr. 20 kg (Manufacturer’s specification) | Manufacturer’s Website
With the new R.XX, ROTWILD are expanding their model range with what’s already their third eMTB powered by an Avinox drive system. While the R.EX is designed as a versatile all-mountain bike and the R.EXC as a no-compromise enduro racer with a focus on maximum downhill performance, the new R.XX takes a different approach. With 160 mm of travel up front, 150 mm at the rear and a system weight of around 20 kg, it’s intended to impress above all with its agile, responsive and engaging ride feel. A firmly tuned suspension, modern trail geometry and powerful Avinox motor are all designed to deliver plenty of flow on demanding trails. Here’s everything we know so far about the new ROTWILD R.XX 2027.
The new ROTWILD R.XX in detail
The new R.XX clearly belongs to the current ROTWILD family, yet it carves out its own visual identity. Its signature seat stays and semi-high pivot suspension layout recall the larger R.EX and R.EXC, albeit in a noticeably slimmer form on the R.XX. The biggest departure lies in the shock integration: rather than mounting upright, the FOX Float X shock runs horizontally through the front triangle, where a distinctive cut-out in the top tube frames it.
ROTWILD is particularly proud of the new Polydynamic carbon frame. Its lay-up uses premium 1,100 UD carbon fibres, claimed to strike an especially favourable balance between low weight and high stiffness. The battery concept contributes to that same goal. Unlike the larger Avinox-powered models, the R.XX forgoes a removable battery in favour of a permanently integrated 700 Wh unit built on cylindrical cell technology, promising high energy density in a compact form factor. Eliminating the battery access port allows for a fully enclosed downtube, saving additional weight while increasing frame stiffness.
The distinctive cut-out has therefore moved from the downtube to the top tube, where it creates space for the shock while also leaving room to mount a full-size water bottle inside the front triangle. The design also improves access to the shock’s adjustment controls.
ROTWILD are also breaking new ground with the geometry. Alongside frame sizes S, M, L and XL, there will also be an additional M/L option. At the same time, the chainstay length grows proportionally with frame size, increasing from 435 mm to 460 mm to ensure balanced handling across the entire size range. Sizes S and M use a mullet setup with a 27.5” rear wheel, while from size M/L upwards, ROTWILD switch to a full 29er. Reach figures increase in 25 mm increments, starting at 425 mm in size S and extending to a very long 520 mm in size XL.

Specification variants of the new ROTWILD R.XX 2027
The new R.XX will be available in four spec variants, with prices ranging from € 8,490 to € 13,490. All models come equipped with FOX suspension, a SRAM drivetrain and brakes, Schwalbe Radial tires and an 8PINS dropper post.
The entry-level R.XX CORE model is the only one in the range to use the slightly less powerful Avinox M2 drive unit, delivering 1,100 W of peak power and 125 Nm of torque in Boost mode. It is also supplied exclusively with the 4 A charger, while the more expensive models come with the 12 A fast charger. Suspension duties are handled by a FOX 36 Rhythm fork with the GRIP damper, while shifting is taken care of by a mechanical SRAM EAGLE 90 Transmission drivetrain. Newmen Beskar aluminium wheels and aluminium handlebars underline the functional character of this entry-level model. Braking is provided by SRAM MOTIVE Bronze brakes paired with 200 mm rotors.
At €9,990, the R.XX PRO steps up to the more powerful Avinox M2S drive unit and an electronic SRAM GX Transmission drivetrain, paired with lightweight Newmen carbon wheels and a FOX 36 Performance fork.
At a hefty € 11,990, the ULTRA model sits firmly in premium territory and comes with significant suspension upgrades. Both the FOX 36 fork and FOX Float shock are specified in Factory trim. That means not only Kashima coating but, more importantly, considerably greater adjustability and, thanks to the GRIP X damper in the fork, improved descending performance while keeping weight low. There are upgrades to the drivetrain and brakes, too. Here, ROTWILD rely exclusively on SRAM X0 components along with the higher-spec Silver version of the MOTIVE brakes.
The € 13,490 R.XX ULTIMATE sits at the very top of the range. It not only benefits from an even more premium specification but also stands out with its exclusive Lava Orange paint finish, which makes a far bolder visual statement than the Bloodfin Red colourway used on the CORE, PRO and ULTRA models. Lightweight SRAM XX drivetrain components and the Ultimate version of the MOTIVE brakes with carbon levers leave little to be desired while helping to reduce the overall weight of the flagship model even further.
With the new R.XX, ROTWILD are further refining their portfolio, filling the gap between the more descent-focused R.EX and R.EXC models. Whether the concept can truly deliver its promised blend of low weight, responsiveness and trail flow, however, is something only real-world testing will reveal.
