Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Trek Fuel EXe 8 GX AXS Full Suspension Electric Mountain Bike 2025 in Rage Red/Dark Blue

Season:2025

Brand:Trek

Code:41478RED

The Fuel EXe 8 is a trail-ready aluminium electric mountain bike that quietly assists you on the climbs so you've got all the power you need on descents. Like its carbon counterpart, it looks and handles like a traditional trail bike, but with the added support of a tiny-but-mighty harmonic pin ring drive system with sleek top-tube display unit and compact remote. It comes ready to rip with upgraded parts where they matter most, like a FOX suspension package, wide Bontrager Line Comp Tubeless Ready wheels and SRAM's 12-speed wireless GX AXS transmission.

Performance matters to you, but so does the price tag. You want all of the tech you'll find in the top-of-the-line Fuel EXe, but in a bike that's built for your budget. You want upgraded components you can trust to keep ripping, and a robust alloy frame that rallies through the rough and gives you just enough power on the ups.

An Alpha Platinum Aluminium frame with TQ's HPR50 harmonic pin ring drive system, a fully-encased 360 Wh removable battery and smart charging port. An integrated LED display and handlebar remote that are easy to use on the fly. 150 mm FOX Rhythm 36 front suspension with Float EVOL air spring and GRIP damper and 140 mm FOX Performance Float X rear suspension. Plus, wide, Tubeless Ready Bontrager Line Comp 30 wheels, SRAM's wireless 12-speed GX AXS transmission, hydraulic disc brakes and a dropper post.

If you want all the tech of the top-tier Fuel EXe without the sticker shock, the Fuel EXe 8 is for you. You get the same drive system, display and geometry of its carbon counterpart, plus an upgraded suspension package and wireless shifting – on a more economical alloy chassis.
