Racing meets All Mountain

From the ROTWILD racing department straight to your home trail: the R.EX combines enduro racing and all-mountain use in one powerful trail bike. It relies on technology proven in the World Cup, starting with the new rear suspension design. For us, this is the benchmark in suspension development because it is even more stable in the suspension travel and ensures more riding fun.

FEATURES

Racing meets all-mountain. The frame construction of the R.EX is an evolution of the ROTWILD World Cup racer R.EXC and has been implemented just as consistently.

Elevated Box Design

Clearly visible at first glance: the appearance of the ROTWILD R.EX is characterized by the new Elevated Box Design and the chainstay that is pulled up sharply.

The Shimano EP801 motor is an outstanding example of innovative e-bike technology and is predestined for use in e-enduro racing and demanding trail riding.

Mid-High Pivot Suspension

The best of both worlds: the swing pivot of the R.EX frame, which has been moved further forward and upward, combines the advantages of a classic four-bar rear suspension with those of a high-pivot setup.

Improved rollover performance and tracking: The 29-inch front wheel makes it easier to roll over obstacles. It also offers better tracking stability.

Every detail counts. When the race really picks up speed, the route profile, line selection, and surface determine the right gear. This is where the Shimano XT-Di2 clearly shows its advantages.

For us, the new design is the benchmark in suspension development, with the mid-high pivot system playing a central role. The bike is more stable in its suspension travel without compromising on drive efficiency.”
