Trek Powerfly+ FS 4 800 Wh Fury Red: big loops in the backcountry

Trek quotes 25.50 kg in size M. Its Fury Red/Dark Star Gloss colourway combines a vivid red with a glossy black.

Who is it for?
For the mountain biker who loves long, varied rides: forest tracks, rocky trails and stretches of road between two massifs. It suits anyone who wants a big energy reserve without paying for a 12-speed drivetrain.
The LVR workshop view
A down tube built for 800 Wh. This frame was designed to house a large battery in the down tube without sacrificing stiffness: the 800 Wh PowerTube slides in via the RIB 2.0 system and comes out in one movement for charging. A 34.9 mm seat tube, internal cable routing and Motor Armor protection complete a package designed to last for several seasons.
| Alpha Platinum (Powerfly+ FS) | Alpha NEXT Platinum (Fuel+ EX 8) | OCLV Mountain (Rail+ 9.7 / 9.8) | |
| Level | e-MTB aluminium, built for robustness first | Lighter aluminium from the Fuel+ range | Trek mountain bike carbon |
| Construction | Down tube sized for 800 Wh | Less material, smaller battery | Carbon main frame, same 800 Wh battery |
| Reference bike | Powerfly+ FS 4 800 Wh, 25.50 kg (M) | Fuel+ EX 8 (TQ 580 Wh) | Rail+ 9.7, 23.73 kg (M) |
| What it means | Big battery, a frame that takes the knocks | Lighter bike, less range | Lighter, different budget |
Put simply: this FS 4 800 Wh follows the FS 4 recipe with an extra 200 Wh of range for just 220 g more (25.50 kg vs 25.28 kg in M). It is the best-value upgrade in the range when your rides get longer.
The 2.40-inch Bontrager Gunnison Elite XR tyres, fitted to Tubeless Ready Kovee rims, offer good all-round grip. We recommend converting them to tubeless: fewer punctures from garrigue thorns, and lower pressures for better comfort.
The Tektro HD-M5140 brakes work on 203 mm rotors front and rear, a size well suited to the weight of an e-MTB. On the regulatory side, the assist cuts out at 25 km/h with 250 W nominal, as on all European electric bikes; you keep control of the modes via the Bosch eBike Flow app.
Which Powerfly+ FS should you choose?
| Model | Motor / battery | Rear / front travel | Drivetrain | Weight (M) |
| Powerfly+ FS 4 | Bosch CX / 600 Wh | 120 / 130 mm | Shimano CUES 10-speed | 25.28 kg |
| Powerfly+ FS 4 800 Wh | Bosch CX / 800 Wh | 120 / 130 mm | Shimano CUES 10-speed | 25.50 kg |
| Powerfly+ 4 800 Wh (hardtail) | Bosch CX / 800 Wh | – / fork only | Shimano CUES 10-speed | 24.90 kg |
| Powerfly+ FS 5 | Bosch CX / 800 Wh | 120 / 160 mm | Shimano Deore/XT 12-speed | 24.58 kg |
Our take: compared with the FS 5 (24.58 kg), this FS 4 800 Wh keeps the same battery for 920 g more, with a simpler 10-speed drivetrain. It is the option for those who put range first.

LVR sizing advice The TranzX dropper post grows with the frame: 100 mm in S, 150 mm in M, 170 mm in L and XL. Between two sizes, the smaller one leaves more standover clearance, which is handy when you have to step off the bike on a tricky section.

Your questions
| Can the tyres be converted to tubeless? | Yes, the rims and tyres are Tubeless Ready; we do the fitting in the workshop. |
| How should the battery be stored in winter? | At half charge, in a dry place at room temperature, topping it up from time to time. |
| Is the red bright? | Yes, a bold red paired with glossy black, very visible in the woods. |
| What is the difference from the FS 5? | The FS 5 moves up to 12 speeds, 4-piston Shimano brakes and a longer-travel Psylo fork. |
|
The LVR Cycles verdict A full-suspension e-MTB that puts range first, for riding big loops one after another without doing the maths. The vivid red and glossy black show off its character.
