For the commuter with a long ride to work, for example between the backcountry and Béziers, on back roads and vineyard tracks. The big battery means you do not have to charge it every day.
Riding loaded without punishing the frame. A bike that rides loaded, with an 800 Wh battery, panniers and mudguards, puts more stress on its frame than a bare mountain bike. The Alpha Platinum aluminium and its integrated mounts are built for this use, and the ABP pivot keeps the suspension active under braking, even when the rack is full and the descent to the village is bumpy.
| Alpha Platinum (Powerfly+ FS) | Alpha NEXT Platinum (Fuel+ EX 8) | OCLV Mountain (Rail+ 9.7 / 9.8) | |
| Level | e-MTB aluminium built to carry loads | Premium mountain bike aluminium, no commuting kit | Mountain bike carbon, no commuting kit |
| Construction | Integrated mounts for loads and mudguards | Finer tube shaping | Impact-resistant carbon layup |
| Reference bike | FS 4 Equipped 800 Wh, 28.30 kg (M) | Fuel+ EX 8 | Rail+ 9.7, 23.73 kg (M) |
| What it means | A bike for everyday use and the trails | Sporty leisure bike | Pure riding machine |
Put simply: this is the heaviest Powerfly+ FS (28.30 kg in M), and it owns it: big battery, full suspension and all the commuting kit on one bike. Compared with the 600 Wh FS 4 Equipped (26.50 kg), you gain 200 Wh of range for 1.80 kg more.
On a daily commute, the 800 Wh battery offers real flexibility: you can ride for several days before charging, and choose a high assist mode when you are in a hurry. The RIB 2.0 battery comes out so you can charge it at the office, and the Purion 200 remote clearly shows the remaining charge.
Assist cuts out at 25 km/h, the standard for European e-bikes with a 250 W nominal motor: on the road, you will cruise at that pace effortlessly. On a 28.30 kg bike, the Pletscher kickstand and the MIK rack become essential for parking and carrying.
| Model | Motor / battery | Rear / front travel | Drivetrain | Weight (M) |
| Powerfly+ FS 4 Equipped | Bosch CX / 600 Wh | 120 / 130 mm | CUES 10-speed + rack | 26.50 kg |
| Powerfly+ FS 4 Equipped 800 Wh | Bosch CX / 800 Wh | 120 / 130 mm | CUES 10-speed + rack | 28.30 kg |
| Powerfly+ 4 Equipped 800 Wh (hardtail) | Bosch CX / 800 Wh | – / fork only | CUES 10-speed + rack | 27.20 kg |
| Powerfly+ FS 4 800 Wh | Bosch CX / 800 Wh | 120 / 130 mm | Shimano CUES 10-speed | 25.50 kg |
Our take: at 28.30 kg in M, this is the heaviest Powerfly+ FS, but also the most complete. The Powerfly+ 4 Equipped 800 Wh hardtail weighs 1.10 kg less (27.20 kg), without rear suspension.

LVR sizing advice At 28 kg ready to ride, choose a size that lets you push and park the bike without effort: standover matters as much as riding position. The TranzX dropper goes from 100 mm in S to 170 mm in L and XL.
