Rotwild R.XX with Avinox M2S: A super-light e-MTB powered by DJI – an explosive combination!

Conclusion from the BIKE editorial team

Lightweight and packed with power: with the R.XX, Rotwild aims to make the most of the Avinox M2S’s unique strengths. Despite the focus on weight, the spec and design remain fully trail-ready. An explosive combination for touring and trail cyclists looking for a particularly lightweight e-mountain bike. The price, as is typical of Rotwild, is exclusive.

First came the first DJI bike with a removable battery, and now the company is aiming for the title of lightest bike with the Avinox M2S: German e-bike manufacturer Rotwild is expanding its range with a completely new e-mountain bike. With the R.XX, the company is launching a trail and all-mountain bike for the 2027 season, specifically aimed at riders looking for an agile, lightweight yet powerful e-MTB. A new record?

Lightweight design concept with integrated battery

Unlike the R.EX and R.EXC e-MTBs, which are designed for downhill performance and feature a quick-release battery, the Rotwild R.XX takes a consistent approach to lightweight construction: The carbon frame, made from high-quality 1100 UD fibres, was manufactured using the so-called Polydynamic process.

The Avinox 700 Wh battery is firmly integrated into the down tube. This design is intended to keep the weight down whilst providing sufficient range for longer rides. The total weight is expected to be around 20 kilograms.

Nevertheless, the bike has been kitted out for trails and serious off-road riding. Forks with 160 mm of travel are designed to provide shock absorption, whilst Schwalbe’s Albert Trail tyres deliver plenty of grip and puncture protection. What’s more, all models feature Fox Float X shock absorbers with a reservoir.

A weight of 20 kilos would be quite impressive for a bike with this specification. By way of comparison: so far, we have weighed two bikes fitted with Avinox’s lightweight and slim 700 battery in the BIKE lab. The Raymon Tarok Ultimate comes in at 20.6 kilos, the Amflow PX Carbon to 21.7 kilos.

Whilst the Raymon’s spec is comparable to that of the Rotwild, the Amflow comes with heavy-duty extras and chunky Gravity tyres. In terms of price, however, the premium R.XX is significantly more expensive than the two competitors mentioned.

The facts

• Suspension travel: 160 mm (front) / 145 mm (rear)
• Engine: Avinox M2 / M2.S, up to 1,500 W power
• Battery: 700 Wh, permanently integrated
• Wheels: 29" (M/L, L, XL), mullet with a 27.5" rear wheel (S, M)
• Five sizes: S, M, M/L, L, XL
• Weight: from approx. 20 kg (manufacturer’s specification)
• Permissible total weight: 130 kg (ASTM4)
• Price: from 8,490 euros

Kinematics for a direct driving experience

At the heart of the suspension design is the so-called ‘Elevated Box Design’, with 145 millimetres of travel at the rear. This design is also featured on Rotwild’s other two Avinox bikes. For the R.XX, however, the swingarm has been made significantly slimmer. The kinematics have been deliberately designed for a lower initial lever ratio, which is intended to result in a stiffer ride and more direct responsiveness. According to the manufacturer, the bike provides more trail feedback and reacts more immediately to the rider’s inputs.

Avinox motor with up to 1500 watts

Depending on the specification, either the Avinox M2 (Core) or the more powerful M2.S (Pro, Ultra, Ultimate) is used. The latter delivers up to 1,500 watts of power in Boost mode with the slim 700 battery and can be customised. The built-in 700 Wh battery can be charged using either a 4A or 12A charger, depending on the model.

Size-dependent geometry

A distinctive feature of the geometry: the rear triangle lengths increase in line with the frame size, and this applies to every single size. Rotwild has gone to considerable lengths to achieve this. What’s more, this new model comes in five sizes rather than four. Whilst sizes S and M are supplied in a mullet setup with a 27.5-inch rear wheel, sizes M/L, L and XL feature 29-inch wheels. The integrated seatpost from Eightpins allows for an adjustment range of up to 240 millimetres in size XL.

Availability and prices

The Rotwild R.XX will be available in four trim levels from 2027. Prices start at a generous €8,490 for the Core version and go up to €13,490 for the Ultimate model. The bike is available in Bloodfin Red (Core/Pro/Ultra) and Lava Orange (Ultimate).
