How it compares
With 150–160 mm at the fork, the Bulls Vuca EVO AM sits above average: across the 101 bikes in the “e-MTB for trail and touring” category in our database, the median is 150 mm. On travel, it slots in between the Bulls Copperhead EVO AM and the Bulls Sonic EN-R in the Bulls range. Depending on the build, the frame is carbon or aluminium.
Bulls quotes 25.5 kg for the 2 build; that is 2.1 kg more than the 23.4 kg median of 49 comparable bikes. There are 0.8 kg between the lightest and the heaviest build. The Bulls Vuca EVO AM is not a budget bike: even the 1 build costs €6,999, while the category median is €5,500. The top build, 3, costs €9,999. For suspension, Bulls combines components from FOX and RockShox. In total, 3 different forks are used, from the RockShox Lyrik Select RC to the FOX Podium Factory-Series. It is powered by Pinion MGU E1.12 25/85Nm. Worth knowing for heavier riders: the maximum system weight is 150 kg – after about 27 kg of bike, that leaves around 123 kg including kit.
Setup notes for this spec
- Fork (RockShox Lyrik Select RC): 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: turn the red FOX and RockShox adjuster fully closed first and count clicks from there – that way you can note settings and restore them later.
- Shock (RockShox Deluxe Select+ RL): 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 Bulls Vuca EVO AM
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 Bulls specifies its own target SAG for your model, that takes priority.
150 mm fork (1)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 26 mm |
| Trail | 20 % = 30 mm |
| Enduro / rough | 22 % = 33 mm |
| Bike park | 20 % = 30 mm |
160 mm fork (2, 3)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 27 mm |
| Trail | 20 % = 32 mm |
| Enduro / rough | 22 % = 35 mm |
| Bike park | 20 % = 32 mm |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
Basis: 2.40″ 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 ST, S / Big Betty Evo SG, S; SCHWALBE Magic Mary Performance.
| Ready-to-ride weight | Front | Rear |
|---|---|---|
| 60 kg | 1.48 bar (21 psi) | 1.68 bar (24 psi) |
| 70 kg | 1.60 bar (23 psi) | 1.80 bar (26 psi) |
| 80 kg | 1.72 bar (25 psi) | 1.92 bar (28 psi) |
| 90 kg | 1.84 bar (27 psi) | 2.04 bar (30 psi) |
| 100 kg | 1.96 bar (28 psi) | 2.16 bar (31 psi) |
| 110 kg | 2.08 bar (30 psi) | 2.28 bar (33 psi) |
| 120 kg | 2.20 bar (32 psi) | 2.40 bar (35 psi) |
Air pressure in the fork and shock
The sticker on the fork (or on the shock) and the manufacturers’ setup charts give you a first pressure. Our calculator is more precise and suggests rebound too – always check the result via SAG.
