There’s no shortage of new eMTBs using the powerful new Avinox drive systems, and Rotwild is adding another to the list with its new R.XX model. Designed to be more active, agile, and lightweight than the brand’s R.EX and R.EXC e-enduro models, the R.XX is aimed at trail and all-mountain riders seeking a livelier, versatile ride. With 145/160mm of travel, “Polydyamic Carbon” frames, up-to-date geometry, and the latest eMTB technology, the R.XX is a unique-looking new model from the smaller German brand.
Rotwild is officially launching the R.XX today at Eurobike. Let’s see what it’s all about.
Rotwild R.XX Details
Rotwild says the R.XX is “engineered for flow” with “maximum lightness, active ride feel, and full power.” With this more trail-oriented platform, the brand says the focus was on agility, efficiency, and versatility, as opposed to the maximum downhill performance of its e-enduro models.
Focus on Weight
One of the main priorities in its design was to keep the weight as low as possible. To do so, Rotwild says it uses “extremely high-quality carbon manufacturing for the frame, sticking to its ‘Polydynamic Carbon’ design and production principle.” The brand’s engineers are striving for continuous improvement in their carbon tech, materials, and build quality.
In the case of the R.XX, they chose 1,100-fiber UD-grade carbon, which is apparently the highest grade available in cycling. They claim their carbon layup with large, continuous inlays reduces stress points and minimizes resin content, resulting in tight tolerances, smooth finishes inside and out, low weight, and high stiffness.
Piggybacking on that, Rotwild made the conscious design choice to have a fixed battery — it can still be removed through the motor area — so that the downtube could be uninterrupted. Because, as Rotwild puts it, “a closed tube is both stable and can be built light.” The unique cutout in the top tube is another such functional design choice, to create enough room for piggyback shocks and full-sized water bottles to fit together in the frame.
Rotwild says the R.XX’s construction and design result in a complete bike weight of around 20 kilograms (44 lbs.), which is very competitive for a full-power eMTB with a 700Wh battery.
Suspension Travel and Frame Details
The R.XX frame gets 145mm of rear wheel travel paired with a 160mm fork. The unique suspension design uses what appears to be a modified four-bar layout with an elevated chainstay/swingarm and a mid-pivot location above the bottom bracket. It’s eye-catching to say the least.
Rotwild says the suspension kinematics are trail-tuned for a livelier feel. They say the lower initial leverage ratio results in “less sag off the top, a firmer baseline feel, and a more active ride. The bike gives you more trail feedback, reacts more directly to your inputs, and begs you to push hard through berms, rollers, and jumps.”
The R.XX comes in five frame sizes, with the M/L, L, and XL sizes rolling on 29” wheels front and rear. The S and M frames come with a mullet setup and a 27.5” rear wheel. All models and sizes include EightPins integrated adjustable length dropper posts — with up to 240mm of drop. The frame has 12 x 248mm Boost rear axle spacing, standard internal cable routing, and one bottle mount — with room for a full-sized water bottle — in the front triangle.
Geometry
As mentioned above, the R.XX comes in five frame sizes. Rotwild says they added the M/L size because analysis of rider height distribution puts many riders between the traditional M and L sizes. The M/L solves that problem, while making it easier for more riders to find a better frame fit.
Geometry-wise, the R.XX aligns with modern standards and its trail/all-mountain-oriented intended use. Key figures shared by all sizes include the 64° head tube angle, 77° seat tube angle, and 345mm bottom bracket height. Reach measurements start at 430mm on the Small, and extend to 520mm on the XL, with the middle M/L frame coming in at 475mm.
Rotwild chose size-specific chainstay lengths for proportionality, starting at 430mm and increasing in 5mm and 7.5mm increments up to 460mm on the XL. Check out the chart below for the rest of the geometry details.
Avinox Drive Systems
Like dozens of other eMTBs launched in the past few months, the Rotwild R.XX is equipped with the latest Avinox drive systems. Three of the four models come with the more powerful M2S motor, while the CORE model gets the slightly less powerful M2. These are the most powerful eMTB motors currently on the market. Here’s a quick rundown of their power specs.
- Avinox M2S: 1,300W and 130Nm continuous, 1,500W and 150Nm Boost Mode
- Avinox M2: 1,100W and 110Nm continuous, 125Nm Boost Mode
As mentioned above, Rotwild chose fixed 700Wh batteries to reduce both frame and battery weight. All models come with the 12A fast charger, except the CORE, which comes with the standard 4A charger. Avinox’s 2” OLED top-tube integrated display makes it easy to see ride info at a glance, with the handlebar-mounted remote to switch between assist modes.
