Aluminium full-suspension electric mountain bike Trek Powerfly+ FS 8 sage blue: Bosch CX 800 Wh, Fox 36 150 mm, 24.88 kg

Trek Powerfly+ FS 8 Blue Sage: XT brakes and a Fox 36 for descending

With its 150 mm Fox Rhythm 36 fork and four-piston Shimano XT M8220 brakes, the Trek Powerfly+ FS 8 has the highest-spec braking in the Powerfly+ FS range. Bosch CX motor, 800 Wh battery, wireless XT Di2 drivetrain and Kiox 300 display: it weighs 24.88 kg in size M according to Trek. Its Blue Sage/Catalina Fog livery plays two blues off each other: a greyish, almost green sage and a rich teal.

Technical specifications

Who is it for?

For the mountain biker who enjoys technical descents and wants powerful, consistent braking, while keeping a versatile e-MTB for big rides. It is aimed at riders who tackle the steep trails of the Espinouse.

The LVR workshop view

Three adjustments to get the most from the 150 mm fork. What this frame brings to the FS 8 is adaptability: Mino Link for geometry, an adjustable ratio for progression, and the ABP pivot to keep the rear active under braking. With a 150 mm fork, these adjustments really come into their own, as they let you balance a more generous front end with the 120 mm at the rear.

Put simply: this FS 8 pairs a 150 mm Fox 36 with the only Shimano XT Di2 drivetrain in the Powerfly+ FS range. At 24.88 kg in M, it is 400 g heavier than the FS 8 with SRAM AXS drivetrain and 130 mm fork, the price of its longer fork and its equipment.

The four-piston XT M8220 brakes on 200 mm rotors deliver top-level power and consistency. Their precise feel lets you modulate your braking on steep, dusty descents. We recommend an annual bleed to maintain that consistency.

The Bontrager Rapid Drive 108 rear hub offers fast engagement, useful for getting back on the power in technical sections. The Bosch assist respects the European limit of 25 km/h with 250 W nominal; it is updated via the Bosch eBike Flow app.

Which Powerfly+ FS should you choose?

Our take: compared with the FS 6 with Fox 36 (25.08 kg), this FS 8 gains 10 mm up front, XT Di2 and XT brakes, for 200 g less (24.88 kg in M).
