R.X375 2026
How current the bike is — newer chassis, motor and battery score higher. 10 = brand-new, 0 = legacy.
The Rotwild R.X375 is a lightweight all-mountain eMTB built around a handmade high-modulus carbon frame, a Shimano EP8 motor (85 Nm) and the brand's compact 360 Wh IPU375 carbon battery. With 150 mm of fork travel, 140 mm at the rear and claimed weights from 19.1 to 19.8 kg, it sits firmly in the light-assist trail category rather than chasing full-power range.
Three builds share the same frame, motor, battery and geometry, so the choice is purely about kit. The Core (EUR 6,490) pairs a FOX 36 Performance fork with Magura MT5 brakes and Shimano XT shifting on alloy-rim Crankbrothers wheels. The Pro (EUR 7,490) upgrades to a FOX 36 Performance Elite fork and full Shimano XT brakes with I9 hubs. The Ultra (EUR 8,990) tops the range with FOX Factory Kashima suspension, Shimano XTR throughout, carbon Crankbrothers wheels and a carbon bar, which accounts for its lower claimed weight.
Geometry is consistent and middle-of-the-road for the segment, with a 66.5 degree head angle, a 75.5 degree effective seat angle and 450 mm chainstays across all four sizes. Reach runs from 430 mm on the S to 500 mm on the XL on a full 29in wheel setup. The figures point to a balanced, agile trail bike rather than an aggressive enduro machine, in line with Rotwild's "Trail King" positioning.
