Corratec E-Power RS C: Two Bavarian carbon full-suspension bikes with Avinox drive systems

Our verdict on the new Corratec E-All-Mountain​

With an identical carbon frame, 160 millimetres of suspension travel and an Avinox drivetrain, Corratec distinguishes the RS-C series primarily through its components and price. The Factory model offers more high-end features, whilst the Pro reduces the entry-level price by 3,000 euros. A practical test will be needed to determine how the suspension, geometry and motor interact off-road.

For the 2027 season, Corratec is expanding its range of e-mountain bikes to include the E-Power RS C Factory and E-Power RS C Pro models. Both feature the same carbon frame, a rear suspension with 160 millimetres of travel, and the Avinox M2S drive system. The main differences between the models lie in the suspension, gear system, brakes and wheels. Whilst the Factory model comes with an electronic SRAM gear system and Fox Factory suspension, the Pro model is designed to offer a significantly lower price thanks to its simpler, mechanical components.

The common foundation is a completely redesigned 29-inch carbon frame with 160-millimetre suspension, 29-inch wheels at both the front and rear, and geometry tailored for trail riding. According to Corratec, the bike is aimed at sporty riders who want to tackle steep climbs as well as fast and technical descents.

The drive system in the Corratec E-Power RS

Corratec has opted for the Avinox M2S as its drive unit. In Boost mode, this Chinese powerhouse delivers up to 150 Newton-metres of torque and a peak power output of 1,500 watts. Power is supplied by the Avinox battery, which is permanently fitted inside the down tube and has a capacity of 800 watt-hours. The system is controlled via the BC-100 wireless controller and the DP-100 display; a 4-amp charger is included in the scope of delivery.

The geometry of the Corratec E-Power RS

​The new RS C Factory is clearly more downhill-oriented than its predecessor: the steering angle is reduced from 65 to 63 degrees, whilst the seat angle is increased from 74 to 77 degrees. In size M, the reach has increased from 445 to 460 millimetres, and the wheelbase from 1,243 to 1,252.8 millimetres. Shorter chainstays and 29-inch wheels at both the front and rear (the previous model had a ‘mullet’ mix) complement the new design direction.

The model variants

The E-Power RS C Factory is the higher-priced model. It features a Fox 36 Float Factory Grip X2 with 160 millimetres of travel and a Fox Float Factory rear shock – a suspension system that offers extensive adjustment options for a variety of trail conditions. The spec also includes an electronic SRAM GX AXS T-Type 12-speed groupset, SRAM Maven Silver brakes with 200-millimetre rotors and a DT Swiss HX1700 wheelset. The 2.4-inch-wide Continental Kryptotal tyres guarantee grip and control on challenging trails. An electronic Fox Transfer dropper post completes the package, for which the Bavarian manufacturer is asking €8,999.

On the E-Power RS C Pro, the frame, suspension travel, motor and battery are identical to those on the more expensive model. The main savings are made on the suspension: the Fox components have been replaced by a RockShox Psylo Gold RC fork and a RockShox Super Deluxe Base rear shock. However, the rest of the spec has also been scaled back compared to the Factory model: shifting is mechanical, using a SRAM Eagle 90 T-Type 12-speed groupset; the braking system consists of SRAM DB6 four-piston brakes, also with 200-millimetre rotors; added to this are the cheaper and heavier DT Swiss H1900 wheelsets and a conventional dropper post with an SRAM lever. Ultimately, the downgraded specifications on the Pro model compared to the Factory model have saved you 3,000 euros: the Pro retails for 5,999 euros. Both models are available in frame sizes S, M and L.
