R.X750

R.X750

PRO (HT)

If blocked single trails in alpine terrain and technical challenges are what you love, the hardtail Big Mountain R.X750 is the bike for you. The lightweight full carbon frame, the Fox 36 forks with 120 mm of suspension travel and the low trail geometry with a steering angle of 66° make it a reliable partner for mountain riders who want to conquer summits but do not go for the most extreme descents.

With its Eightpins seat post and low top tube, the R.X750 hardtail offers you plenty of freedom of movement and agility. The combination of a 29” front wheel and 27.5” rear wheel guarantees outstanding handling. The 29x2.4 tyre on the front provides excellent rollover resistance and reduces the feeling of front-tipping in downhill sections, while the 27.5x2.6 tyre on the back gives better traction.

IPU750 Semi-Integrated Battery

Semi-integrated, easily removable battery with 750 Wh for more elevation gain and Brose Drive S-Mag with 90 Nm maximum power, the benchmark for power delivery, precise sensor system and weight

Double Wall Tube

Special hollow chamber design combines the outer shell with the inner tube around the heavily stressed head tube area, thereby achieving a high level of stability and stiffness at minimal weight

Tailored Wheel Size

Wheel size mix with 27.5" rear wheel and 29" front wheel, which combines the best of both worlds: great steering stability and optimal roll-over characteristics paired with a maximum of damping and traction

Integrated Carbon Motor Case

Maximum stiff connection from head tube via down tube to the motor shaft for very precise riding characteristics. Special Air Skid Plate protects the motor housing and dissipates heat to the outside

 

You will no longer feel intimidated by long steep climbs and all-day touring in rough terrain with the IPU750 integrated power unit and the Brose Drive S Mag motor to help you. The new tailor-made lightweight ROTWILD battery sets new standards. It produces 750 Wh and is based on the latest 21700 cell technology. The powerful Brose Drive S Mag motor has a maximum power output of 90 Nm over a broad cadence range and a faster response in technical terrain. In addition, the motor cuts out completely at the statutory speed limit, which allows you to pedal without resistance at speeds above 25 km/h. You can use a smartphone app to customise the levels of support, from highly efficient to extremely powerful, to suit your personal preferences.
