Big Mountain at its best! Semi-integrated, 750 Wh battery in compact carbon fibre casing, 150 mm FOX E-Bike+ fork, 8PINS seat post.
If trails are your thing then the R.X750 is the bike for you! Big Mountain at its best, with a powerful drive and forgiving chassis. The new IPU750 power unit in combination with the Brose Drive S-Mag motor is the benchmark for use in steep, challenging terrain. The semi-integrated, powerful 750 Wh battery uses the newest cell technology in a compact, robust aluminium housing; the ULTRA version even has a carbon fibre casing.
The natural sensitivity of the Brose Drive S-Mag motor lends a real bike feeling to the R.X750; a maximum of 90 Nm torque allows the metres to melt away as you climb and the fun to increase. The 150 mm chassis was entirely designed for superior Big Mountain use in order to achieve a higher degree of efficiency and improve downhill characteristics. The carbon frame of the R.X750 is light and extremely stiff, which combined with its speed-orientated descent geometry with low top tube, low damper, 66° steering angle and 74° seat angle, as well as a longer reach, ensures plenty of freedom of movement.
A 29 front wheel combined with a 27.5 back wheel facilitates great handling; the 29 tyre improves the bike's behaviour when rolling over obstacles and reduces flip-over sensations while the nimble 27.5 tyre provides great agility on descents.
