Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

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.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery & Collection Dates

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

Trek Fuel EXE 8 XT Electric Mountain Bike 2025 Satin Mercury

Season:2025

Brand:Trek

Code:41503GRY

The Trek Fuel EXe 8 Electric Mountain Bike is a trail-ready aluminium 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 a Shimano XT 12-speed drivetrain.

It's right for you if...

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.

The tech you get

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, a 12-speed Shimano XT drivetrain, hydraulic disc brakes and a dropper post.

The final word

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 Shimano XT drivetrain – on a more economical alloy chassis.

Trek Fuel EXe 8 Electric Mountain Bike Highlights

  • You get all the tech of our top-end light e-MTB without a price tag that makes you say ouch
  • Its upgraded FOX suspension package smooths the trail while a 12-speed Shimano XT drivetrain shifts clean under load
  • Its tiny-but-mighty TQ motor is tuned for the trail, keeping things quiet so you can stay in the moment, and ramps up power with you for a natural ride feel
  • The integrated display, charging port, and controls are simple to use, sleek and intuitive
  • You can tweak your geometry with Mino Link, or add an adjustable angle headset to take even more control
