|---|---|---|---|---|---|---|---|---|
| 500 | RockShox Zeb (180 mm) | RockShox Vivid Base | – | 180 mm | Bosch Performance Line CX (120Nm) 800 Wh | – | €5,499 | Setup → |

How it compares
180 mm at the fork almost exactly matches the 180 mm median of the 5 bikes in the “e-freeride bike” category in our database. Front and rear both work with 180 mm of travel. No other Merida model among its e-mountain bikes has more travel up front. Merida builds the frame from aluminium.
At €5,499 for the 500 build, pricing is typical for the category (median €6,000). For the 900 build, Merida asks €7,199. Fork and shock come from RockShox on every build. The fork line-up ranges from the RockShox Zeb to the RockShox Zeb Ultimate. It is powered by Bosch Performance Line CX (120Nm) with a 800 Wh battery.
Setup notes for this spec
- Fork (RockShox Zeb): 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 RockShox adjuster fully closed first and count clicks from there – that way you can note settings and restore them later.
- Air shock (RockShox Vivid Base): measure SAG in your riding position, ideally with a helper holding the bike. Cycle the shock a few times after every pressure change.
- 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 Merida eONE-EIGHTY
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 Merida specifies its own target SAG for your model, that takes priority.
180 mm fork (all builds)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 31 mm |
| Trail | 20 % = 36 mm |
| Enduro / rough | 22 % = 40 mm |
| Bike park | 20 % = 36 mm |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
The values apply to 2.50″ 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: Maxxis Assegai / Maxxis Minion DHR II 29x2.5 ".
| 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.
