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.

Size	S	M	L	XL
Rider height (cm)	155-165	165-177	177-188	188-195
Inseam (cm)	74-78	79-83	84-89	89-91
Dropper post (mm)	100	150	170	170
Wheels (in)	27.5	29	29	29

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.
