Ibis Oso: suspension setup & specs
The Ibis Oso is an e-enduro bike with 140–180 mm of fork travel and 130–165 mm at the rear. It is powered by Bosch Performance Line CX (Gen 5). This page lists the 3 current builds with fork, shock and shock size and gives matching starting values for SAG and tyre pressure.

How it compares
At 140–180 mm, fork travel is 10 mm shorter than the median of the “e-enduro bike” category (170 mm, 56 bikes). The frame is made of carbon.
Drive comes from Bosch Performance Line CX (Gen 5), paired with 600 Wh of battery capacity. Depending on build or size, the wheels are 29" · MX possible via dropout / MX · 29" possible via dropout.
Setup notes for this spec
- Shock (Check manually): 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 Ibis Oso
SAG is the share of travel your weight already uses in the riding position. The table gives it straight in millimetres – read the O-ring on the stanchion and on the shock shaft and adjust the air pressure until it matches. Any figures from Ibis take priority.
180 mm fork (HD)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 31 mm |
| Trail | 20 % = 36 mm |
| Enduro / rough | 22 % = 40 mm |
| Bike park | 20 % = 36 mm |
140 mm fork (S)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 24 mm |
| Trail | 20 % = 28 mm |
| Enduro / rough | 22 % = 31 mm |
| Bike park | 20 % = 28 mm |
160 mm fork (TR)
| 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
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).
| 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.
