Picnic, windproof and lock in the panniers: the Trek Powerfly+ FS 4 Equipped Gen 4 is made for long days out. This aluminium full-suspension electric mountain bike combines a Bosch CX motor, a 600 Wh battery, a MIK-compatible rack, mudguards and a kickstand, for 26.50 kg in size M according to Trek. Its Pennyflake/Black Olive colourway blends a sparkling copper orange with a very dark olive green.

For the leisure rider who loves linking up the villages of the hinterland, stopping at the market and coming back along the tracks. Also for families riding alongside children and carrying snacks for everyone.
An alloy frame designed to be kitted out. A mountain bike frame that also has to carry panniers needs solid mounting points: this one has rack and mudguard mounts built in from the factory, which avoids makeshift clamps on the seatstays. Alpha Platinum aluminium copes well with this dual use, and the RIB 2.0 battery comes out one-handed for charging at the office or at home.
| Alpha Platinum (Powerfly+ FS) | Alpha NEXT Platinum (Fuel+ EX 8) | OCLV Mountain (Rail+ 9.7 / 9.8) | |
| Level | Versatile aluminium, ready to be kitted out | Premium mountain bike aluminium | High-end mountain bike carbon |
| Construction | Integrated rack and mudguard mounts | Slimmer tubes, no utility role | OCLV lay-up focused on impact resistance |
| Reference bike | Powerfly+ FS 4 Equipped, 26.50 kg (M) | Fuel+ EX 8 | Rail+ 9.8, 23.98 kg (M) |
| What it means | Commutes and trails on the same bike | Sportier, nothing for carrying loads | Lighter, no urban kit |
Put simply: compared with the standard FS 4 (25.28 kg), the Equipped pack adds 1.22 kg on the scales, but also a rack, two mudguards and a kickstand fitted and adjusted at the factory. Buying these accessories afterwards costs workshop time and doesn't always give such a clean fit.
The MIK system lets you clip on a compatible basket or pannier in a second, and take it off to bring with you when you stop for a break. With weight over the rear, the four-piston Tektro brakes and their 203 mm rotors keep a comfortable margin on the descents towards Lac du Salagou.
The Bosch CX motor stops pushing above 25 km/h, the legal limit for European e-bikes at 250 W rated, but it delivers plenty of torque at low speed, which matters when the bike is loaded. Remember to adjust the rear shock pressure to the weight of the panniers: we will show you how.
| 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 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 |
Our take: the 600 Wh Equipped is the lightest option for riding loaded on full suspension (26.50 kg in M). The Powerfly+ 4 Equipped 800 Wh hardtail weighs 27.20 kg with more battery, but no rear suspension.

LVR sizing advice For mixed commuting and trail use, go for the size that lets you put a foot down easily when you stop: with a loaded rack, standover matters. Size S runs 27.5 inch wheels, with mudguards to match that wheel size.

| Can I fit a child seat? | It depends on the seat model and the rack; we check compatibility with you in store. |
| Should I add air to the shock when loaded? | Adjusting its pressure to the total weight improves comfort; it only takes a moment with a shock pump. |
| Do the mudguards stay put on the trail? | Yes, they are designed for this frame and matched to the wheel size. |
| Is the orange easy to touch up? | A sparkling finish is hard to touch up; a protective film fitted in the workshop prevents chips. |

The LVR Cycles verdict The full-suspension e-MTB for all-day rides with luggage, easy to live with and reassuring under braking. The copper orange and olive green give it the look of an adventure bike.
