R.X375 2025
How current the bike is — newer chassis, motor and battery score higher. 10 = brand-new, 0 = legacy.
The Rotwild R.X375 is a deliberately lightweight, full-carbon trail eMTB that pairs a 150/140 mm 29er chassis with a compact 360 Wh IPU375 battery and a Shimano EP8 motor rated at 85 Nm. Claimed weights from 19.1 to 19.8 kg are notably low for a full-power machine, and Rotwild positions it for riders who want an analogue-feeling bike with assistance held in reserve for an extra lap rather than all-day range.
The geometry is moderate by current standards: a 66.5 degree head angle, 75.5 degree effective seat angle and a fixed 450 mm chainstay across all four sizes, with reach growing from 430 mm (S) to 500 mm (XL). The 345 mm BB height and 1184 to 1266 mm wheelbase point to an agile, playful character rather than an outright descender, in keeping with the small-battery, low-weight brief.
All three trims share the same frame, motor and battery, so the choice is purely about parts. Core gets a FOX Performance fork, Magura MT5 brakes and Shimano XT shifting at 6,490 euro. Pro steps up to a Performance Elite fork and full Shimano XT brakes for 7,490 euro. Ultra at 8,990 euro adds FOX Factory Kashima suspension, XTR drivetrain and brakes, e*thirteen Race Carbon cranks and bar, and a longer-drop 8PINS NGS 2 dropper. The Pro looks the value pick, with the Ultra reserved for those wanting the Factory suspension and carbon finishing kit.
