Merida eONE-EIGHTY FR: suspension setup & specs
The Merida eONE-EIGHTY FR is an e-freeride bike with 180 mm of fork travel and 180 mm at the rear. It is powered by Bosch Performance Line CX (120Nm). Below you will find all 1 current builds with fork, shock and shock size, plus SAG values in millimetres and a tyre pressure table.

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

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. The frame is made of aluminium.
At €6,599 for the 800 build, pricing is typical for the category (median €6,000). Fork and shock come from RockShox on every build. The 800 build uses a coil shock (RockShox Vivid Coil Ultimate), so SAG is set with the spring rate rather than air pressure. It is powered by Bosch Performance Line CX (120Nm) with a 800 Wh battery.
Setup notes for this spec
- Air fork (RockShox Zeb Ultimate): 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 RockShox suspension the rebound adjuster is red. Always count clicks from fully closed (clockwise to the stop) so you can return to any setting.
- Coil spring (RockShox Vivid Coil Ultimate): if SAG is off, only a different spring rate will fix it. Preload should just keep the spring from rattling; more preload makes the shock less supple.
- 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 Merida eONE-EIGHTY FR
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
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.
