How it compares
On travel, the Rotwild R.X375 is right where the “e-MTB for trail and touring” category usually is: 150 mm up front against a median of 150 mm from 101 bikes. The fork has 10 mm more travel than the rear end with 140 mm – a common layout that takes load off the front on steep terrain. Within Rotwild’s e-mountain bikes, it sits between the Rotwild R.X275 and the Rotwild R.EX on travel. Rotwild builds the frame from carbon.
The Rotwild R.X375 does well on weight: 18.6 kg for the ULTRA build is 4.8 kg below the median of comparable bikes (23.4 kg). Within the range, weight varies by 1.2 kg. With a starting price of €6,490 (CORE), the Rotwild R.X375 is above the category median (€5,500). For the ULTRA build, Rotwild asks €8,990. Rotwild uses FOX suspension throughout. The fork line-up ranges from the FOX 36 Float Performance to the FOX 36 Float Factory. It is powered by Shimano EP8 with a 360 Wh battery. Rotwild specifies a maximum system weight of 130 kg. Subtracting roughly 20 kg for the bike leaves about 110 kg for rider, clothing, backpack and luggage.
Setup notes for this spec
- Fork (FOX 36 Float Performance): air goes in through the valve on top of the left leg. After every change, compress the fork firmly a few times before measuring SAG.
- Rebound: on FOX suspension the rebound adjuster is red. Always count clicks from fully closed (clockwise to the stop) so you can return to any setting.
- Shock (FOX Float DPS Performance): get on the bike in your normal riding position, step off carefully and read the O-ring. Always cycle the shock a few times after pumping.
- e-MTB: because of the extra weight, start with slightly more tyre pressure – the surcharge is already built into the table below.
Target SAG for the Rotwild R.X375
SAG is the share of travel your weight already uses in the riding position. The table gives it straight in millimetres – read the O-ring on the stanchion and on the shock shaft and adjust the air pressure until it matches. Any figures from Rotwild take priority.
150 mm fork, 50.0 mm shock stroke (all builds)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 26 mm | 24 % = 12.0 mm on the shock shaft |
| Trail | 20 % = 30 mm | 28 % = 14.0 mm on the shock shaft |
| Enduro / rough | 22 % = 33 mm | 30 % = 15.0 mm on the shock shaft |
| Bike park | 20 % = 30 mm | 27 % = 13.5 mm on the shock shaft |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
The values apply to 2.60″ wide tubeless tyres with a trail casing, including the e-MTB surcharge. With an inner tube add about 0.2 bar (2.9 psi), with an insert take off about 0.1 bar (1.5 psi). Stock tyres: SCHWALBE Nobby Nic Evo / SCHWALBE Nobby Nic Evo.
| Ready-to-ride weight | Front | Rear |
|---|---|---|
| 60 kg | 1.40 bar (20 psi) | 1.60 bar (23 psi) |
| 70 kg | 1.52 bar (22 psi) | 1.72 bar (25 psi) |
| 80 kg | 1.64 bar (24 psi) | 1.84 bar (27 psi) |
| 90 kg | 1.76 bar (26 psi) | 1.96 bar (28 psi) |
| 100 kg | 1.88 bar (27 psi) | 2.08 bar (30 psi) |
| 110 kg | 2.00 bar (29 psi) | 2.20 bar (32 psi) |
| 120 kg | 2.12 bar (31 psi) | 2.32 bar (34 psi) |
Air pressure in the fork and shock
You will find a suitable starting pressure on the sticker on the fork stanchion (or on the shock) or in the suspension manufacturers’ setup charts. Our calculator gives you a starting value including rebound for your weight and riding style. What matters afterwards is the measured SAG from the table above.
