How it compares
With 180 mm at the fork, the Giant Reign Advanced E+ sits above average: across the 56 bikes in the “e-enduro bike” category in our database, the median is 170 mm. The fork has 10 mm more travel than the rear end with 170 mm – a common layout that takes load off the front on steep terrain. Among Giant’s e-mountain bikes, the Giant Reign Advanced E+ is the model with the most fork travel. The frame is made of carbon.
23.2 kg for the 1 build puts the Giant Reign Advanced E+ mid-pack on weight (median: 23.5 kg). There are 0.5 kg between the lightest and the heaviest build. At €7,000 for the 2 build, pricing is typical for the category (median €6,900). For the 0 build, Giant asks €10,000. Depending on the build, fork and shock come from FOX and RockShox. In total, 3 different forks are used, from the RockShox ZEB Select Charger to the FOX 38 Factory GRIP X2. With the FOX DHX Performance Elite (coil), the 1 build has a coil shock – here the spring rate determines SAG. It is powered by Giant SyncDrive Pro3X (100 Nm) with a 560 Wh battery.
Setup notes for this spec
- Air fork (RockShox ZEB Select Charger): 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 and RockShox adjuster fully closed first and count clicks from there – that way you can note settings and restore them later.
- Coil shock (FOX DHX Performance Elite (coil)): SAG is determined by the spring rate. Only add enough preload to stop the spring from rattling.
- Shock (RockShox Super Deluxe Select RT): 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 Giant Reign Advanced E+
Instead of percentages, this table gives SAG directly in millimetres, measurable with the O-ring on the stanchion and on the shock shaft. Change the pressure step by step until you reach the value; if Giant gives its own target SAG, use that.
180 mm fork (2, 1)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 31 mm |
| Trail | 20 % = 36 mm |
| Enduro / rough | 22 % = 40 mm |
| Bike park | 20 % = 36 mm |
180 mm fork, 62.5 mm shock stroke (0)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 31 mm | 24 % = 15.0 mm on the shock shaft |
| Trail | 20 % = 36 mm | 28 % = 17.5 mm on the shock shaft |
| Enduro / rough | 22 % = 40 mm | 30 % = 18.8 mm on the shock shaft |
| Bike park | 20 % = 36 mm | 27 % = 16.9 mm on the shock shaft |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
For 2.50″ wide tyres, tubeless with a trail casing, including the e-MTB surcharge. With an inner tube about 0.2 bar (2.9 psi) more, with an insert about 0.1 bar (1.5 psi) less. Stock tyres: Maxxis Assegai 29x2.5 / Minion DHR II 27.5x2.4.
| 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.
