E-performance meets competitive sport

When every second counts and enduro racing is your thing, are you ready to take your passion to a whole new level? If so, read on: we developed the R.EXC together with World Cup pros specifically for the demands of e-enduro racing. Its outstanding innovation, the elevated box design of the rear triangle, guarantees one thing: it makes you faster! With the Mid-High Pivot System, you can easily master steep power stages and demanding descents.

FEATURES

Full carbon frame

In racing, you have to be able to rely unconditionally on your equipment; there is no room for compromise in a race.

Elevated Box Design

The silhouette of the ROTWILD R.EXC is characterized by the new Elevated Box Design and the chainstay that is pulled up sharply.

Shimano EP801 motor

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

Mid-High Pivot Suspension

Der weiter nach vorne und oben verlegte Schwingendrehpunkt des R.EXC Rahmens kombiniert die Vorteile eines klassischen Viergelenker-Hinterbaus mit denen eines High-Pivot Setups.

IPU Carbon Battery 820 Wh

The latest generation technology for greater range:

Mullet Setup

Das R.EXC Bike steht auf Mullet Bereifung. Vorne sorgt das 29“ Vorderrad für das notwendige Überrollverhalten und Spurstärke.

Shimano XT-Di2

Jedes Detail zählt. Wenn es im Rennen richtig schnell wird, entscheiden Streckenprofil, Linienwahl und Untergrund über den passenden Gang.

Flip Chip +/- 5 mm

Die Kettenstrebenlänge des R.EXC Rahmens kann um 5mm von 436 mm auf 441 mm angepasst werden.
