More performance and effortlessness. DT Swiss HX1501 Spline One wheel set, Shimano XT Group, 8PINS H01 Remote seat post. The new trail benchmark.
Aggressive. Light. Agile. Our R.X375 is bringing the core of mountain biking back to the eMTB sport. Made for everyone who loves the riding dynamics and performance of an analogue mountain bike, but doesn't want to go without an electric motor for that extra round. Agility and liveliness are two core components of this, therefore we have made our new R.X375 trail king particularly light.
. It features the newest 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 375 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 of the AGGRESSIVE series 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.
