Rotwild R.X750: suspension setup & specs
The Rotwild R.X750 is an e-MTB for trail and touring with 150 mm of fork travel and 152 mm at the rear. It is powered by Brose Drive S Mag. Below you will find all 1 current builds with fork, shock and shock size, plus SAG values in millimetres and a tyre pressure table.

All builds
Fork, shock, shock size (eye-to-eye length × stroke) and rear travel, motor, weight and price according to the manufacturer. Wheel size: MX.

|---|---|---|---|---|---|---|---|---|

How it compares
On travel, the Rotwild R.X750 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. At 152 mm the rear has 2 mm more travel than the front, which is rare. 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.
At 23.6 kg (PRO build), the weight is close to the category median of 23.4 kg. The Rotwild R.X750 is not a budget bike: even the PRO build costs €7,990, while the category median is €5,500. Rotwild uses FOX suspension throughout. Drive comes from Brose Drive S Mag, paired with 720 Wh of battery capacity. Rotwild specifies a maximum system weight of 130 kg. Subtracting roughly 24 kg for the bike leaves about 106 kg for rider, clothing, backpack and luggage.
Setup notes for this spec
- Air fork (FOX 36 Float Factory): 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: 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 X Factory): 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: the extra weight mainly affects tyre pressure, which is why the table below already includes a surcharge. SAG is measured just as on a bike without a motor.
Target SAG for the Rotwild R.X750
Instead of percentages, this table gives SAG directly in millimetres, measurable with the O-ring on the stanchion and on the shock shaft. Change the pressure step by step until you reach the value; if Rotwild gives its own target SAG, use that.
150 mm fork, 60.0 mm shock stroke (all builds)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 26 mm | 24 % = 14.4 mm on the shock shaft |
| Trail | 20 % = 30 mm | 28 % = 16.8 mm on the shock shaft |
| Enduro / rough | 22 % = 33 mm | 30 % = 18.0 mm on the shock shaft |
| Bike park | 20 % = 30 mm | 27 % = 16.2 mm on the shock shaft |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
Basis: 2.60″ tyre width, tubeless, trail casing, including the e-MTB surcharge. If you run tubes, add about 0.2 bar (2.9 psi); with an insert, about 0.1 bar (1.5 psi) less is enough. Stock tyres: SCHWALBE Magic Mary Evo / SCHWALBE Hans Dampf 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.
