The king of the trail

Aggressive. Light. Agile. Made for all those who love the riding dynamics and performance of an analogue mountain bike, but don't want to do without an e-drive for that extra lap. Agility and nippiness are two core competences of our new trail king R.X375.

What it matters

It features the proven generation of electric motors from Shimano, the EP8. Weighing in at only 2,500g, it provides a solid 85 Nm of torque and 50% less pedalling resistance - a new benchmark in terms of installation space and weight. Combined with the 360 Wh battery, the R.X375 is an exceptionally light eMTB, with plenty of play in handling and is superior on single trails. The handcrafted full carbon frame made up of high modulus carbon fibre plays a significant role in this with the excellent rigidity values and low weight forming the basis for spectacular riding fun.

The kinematics and geometry were also optimised for action. The R.X375 allows for more movement in the chassis, bigger jumps and higher speed; the modern geometry with shallow steering angle and steep seat angle yields a central, well-balanced seat position for optimal control. The R.X375 is on its way "Back To The Roots" - more person, less machine.

High Modulus Carbon

Handmade full carbon frame made of high modulus fibre with optimised carbon layup offers higher stiffness values at absolutely optimised weight. Linkage and shock yoke are also made entirely of carbon.

Fully Integrated Cable Routing

Precise shifting by avoiding tight radii, optimal protection and a tidy look guarantee the cables fully integrated through the cable shaft in the down tube and the motor housing.

ROTWILD IPU375

The target group-specific energy storage convinces with a battery capacity of 360 Wh and high-performance cell technology (type 21700/5.0 Ah) at a minimal, low-positioned weight of 1.9 kg thanks to the weight-optimized, handmade carbon housing.

Shimano EP8

Maximum acceleration and efficient pedaling with natural driving feel guarantees the Shimano Motor with just under 2,500 g, 85 Nm, low pedaling resistance, high motor efficiency at low noise levels and seamless fade-out / fade-in at the support limit. In addition, the support mode can be configured via three different maps.
