How it compares
At 130 mm, fork travel is 20 mm shorter than the median of the “e-MTB for trail and touring” category (150 mm, 101 bikes). The rear offers 120 mm, 10 mm less than the front. Of Rotwild’s e-mountain bikes, the Rotwild R.X275 offers the least travel up front. The frame is made of carbon.
The Rotwild R.X275 does well on weight: 15.3 kg for the ULTRA build is 8.1 kg below the median of comparable bikes (23.4 kg). There are 1.2 kg between the lightest and the heaviest build. The starting price of €5,990 (CORE) is roughly in line with the category median (€5,500). For the ULTRA build, Rotwild asks €7,990. Fork and shock come from FOX on every build. The fork line-up ranges from the FOX 34 Float Performance Elite to the FOX 34 Float Factory. It is powered by TQ HPR50 with a 250–252 Wh battery.
Setup notes for this spec
- Air fork (FOX 34 Float Performance Elite): the air valve is on top of the left leg under a cap. Change pressure in small steps (about 5 psi (0.34 bar)) and cycle the fork a few times afterwards so the air chambers can equalise.
- Rebound: turn the red FOX adjuster fully closed first and count clicks from there – that way you can note settings and restore them later.
- 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.X275
The table converts the recommended SAG percentages into millimetres, so you can check them with the O-ring directly on the stanchion and on the shock shaft. Adjust the air pressure until the value is right. If Rotwild specifies its own target SAG for your model, that takes priority.
130 mm fork, 45.0 mm shock stroke (all builds)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 22 mm | 24 % = 10.8 mm on the shock shaft |
| Trail | 20 % = 26 mm | 28 % = 12.6 mm on the shock shaft |
| Enduro / rough | 22 % = 29 mm | 30 % = 13.5 mm on the shock shaft |
| Bike park | 20 % = 26 mm | 27 % = 12.2 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 Wicked Will 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.
