How it compares
150 mm at the fork almost exactly matches the 150 mm median of the 101 bikes in the “e-MTB for trail and touring” category in our database. The fork has 6 mm more travel than the rear end with 144 mm – a common layout that takes load off the front on steep terrain. On travel, it slots in between the Rotwild R.X275 and the Rotwild R.EX in the Rotwild range. Rotwild builds the frame from carbon.
The Rotwild R.X735 does well on weight: 21.2 kg for the ULTRA build is 2.2 kg below the median of comparable bikes (23.4 kg). Within the range, weight varies by 0.8 kg. With a starting price of €7,490 (CORE), the Rotwild R.X735 is above the category median (€5,500). For the ULTRA build, Rotwild asks €11,990. Fork and shock come from FOX on every build. In total, 3 different forks are used, from the FOX 36 Float Performance to the FOX 36 Float Factory. Drive comes from Shimano EP801, paired with 720 Wh of battery capacity. Rotwild specifies a maximum system weight of 130 kg. Subtracting roughly 22 kg for the bike leaves about 108 kg for rider, clothing, backpack and luggage.
Setup notes for this spec
- Air fork (FOX 36 Float Performance): 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 X 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.X735
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.
150 mm fork, 52.5 mm shock stroke (all builds)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 26 mm | 24 % = 12.6 mm on the shock shaft |
| Trail | 20 % = 30 mm | 28 % = 14.7 mm on the shock shaft |
| Enduro / rough | 22 % = 33 mm | 30 % = 15.8 mm on the shock shaft |
| Bike park | 20 % = 30 mm | 27 % = 14.2 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 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 guide value for air pressure on the fork sticker (or on the shock) or in the suspension makers’ charts. Our calculator also takes riding style and rebound into account. In the end, measured SAG is what counts.
