All builds

Fork, shock, shock size (eye-to-eye length × stroke) and rear travel, motor, weight and price according to the manufacturer. Wheel size: MX.

How it compares

150 mm at the fork almost exactly matches the 150 mm median of the 101 bikes in the “e-MTB for trail and touring” category in our database. Front and rear both work with 150 mm of travel. Within Flyer’s e-mountain bikes, it sits between the Flyer Uproc SL:X and the Flyer Uproc EVO:X on travel. Flyer builds the frame from carbon.

At a minimum of 26.0 kg (G1 2.10 build), the Flyer Uproc X is heavier than its category median of 23.4 kg – 2.6 kg more. At €4,999 for the G1 2.10 build, pricing is typical for the category (median €5,500). For the G1 9.50 build, Flyer asks €11,299. Depending on the build, fork and shock come from FOX, RockShox and SR Suntour. In total, 5 different forks are used, from the RockShox 35 Silver TK Solo Air to the FOX 36 Float Factory. Drive comes from Panasonic GX Ultimate Pro FIT or Bosch Performance Line CX GEN4, paired with 625–750 Wh of battery capacity. Worth knowing for heavier riders: the maximum system weight is 140 kg – after about 26 kg of bike, that leaves around 114 kg including kit.

Setup notes for this spec

• Fork (RockShox 35 Silver TK Solo Air): 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: on FOX and RockShox suspension the rebound adjuster is red. Always count clicks from fully closed (clockwise to the stop) so you can return to any setting.
• Air shock (RockShox Deluxe Select): 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: because of the extra weight, start with slightly more tyre pressure – the surcharge is already built into the table below.

Target SAG for the Flyer Uproc X

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 Flyer take priority.

150 mm fork, 60.0 mm shock stroke (all builds)

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). Stock tyres: Onza Porcupine TRC / GRC 29 x 2,40 / 27,5 x 2,60; Onza Porcupine TRC 29 x 2,40 / 27,5 x 2,60.

Air pressure in the fork and shock

You will find a suitable starting pressure on the sticker on the fork stanchion (or on the shock) or in the suspension manufacturers’ setup charts. Our calculator gives you a starting value including rebound for your weight and riding style. What matters afterwards is the measured SAG from the table above.
