EMTB Forums verdict
The R.X750 was the flagship of Rotwild's 'Big Mountain' category for 2022: a handmade full carbon 150/152 mm mixed-wheel eMTB built around the Brose Drive S Mag motor and the brand's own quick release IPU750 750 Wh battery. It sat between the lighter all-mountain R.X375 and the enduro R.E750 in the German range, pitched at technical alpine climbing and descending.
All three trims shared the frame, motor, battery and Schwalbe Magic Mary/Hans Dampf tyre pairing, so the money went on suspension and drivetrain. The Core (7,499 euro) ran Fox Performance dampers, Shimano XT shifting and Magura MT5 brakes; the Pro (8,999 euro) added XT four-piston brakes, DT Swiss HX 1501 wheels and an Eightpins H01 dropper; the Ultra (11,999 euro) topped out with Factory Kashima suspension, full XTR, carbon DT Swiss HXC 1501 wheels and the longer stroke Eightpins NGS 2 post.
Geometry is moderate rather than radical, with a 66 degree head angle, 445 mm chainstays and a 437 mm reach in M, plus a usefully low 750 mm standover across all four sizes. The bike is discontinued: Rotwild relaunched the R.X750 name on a redesigned platform for 2023.

What the numbers mean on the trail
Computed from this bike's geometry, spec and build kit — reach, wheelbase, chainstay, head and seat angles, travel, motor, weight and the fork/tyre/brake spec — and worked out per size, because a fixed chainstay can make an S and an XL feel very different.
Size
Playfulness
62
A fair bit of pop, but happiest on flowing trail rather than trials moves.
Size balance
98
Rear-long with a planted front in L (FC:RC 1.78) — easy to weight the front and quick to turn, though it can feel light at the back at real speed.
Technical climbing
67
Climbs well — a 74° seat keeps the front planted. 560W of peak power and 90Nm of torque — a strong full-power motor.
No single standout trait — a balanced, versatile bike.
The numbers are well balanced for its category.
