The 2025 Trek Fuel EXe 8 XT Full Suspension Electric Mountain Bike 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.
The Fuel EXe 8 is built around 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.
The Fuel EXe 8 comes 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.
This bike is perfect for
Mountain bikers who 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, and a robust alloy frame that rallies through the rough and gives you just enough power on the ups.

- 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
Electric Bike Updates and Diagnostics
As electric bikes have become more sophisticated it’s important to stay on top of updates. Just like your home computer or smart phone regular updates are now released for most electric bike systems. If you buy a bike from Cycles UK we will do electric bike updates and diagnostics you need free of charge.
Electric Bike Updates
Electric bike updates can help to improve battery life, tweak how the motor works and fix bugs and problems. Most systems will require you to plug your bike into some specialist software at an authorised dealer. At Cycles UK we are authorised dealers for top electric bike brands including Specialized, Trek, Orbea, Whyte, Cannondale and Raleigh. As a result our stores have the software and hardware to run updates on all the major electric bike systems including Bosch, Shimano and Ebikemotion.
Free Electric Bike Updates and Diagnostics
We now provide free updates and diagnostics for life on any electric bike purchased from Cycles UK.
Electric Bike Motors Explained
Electric bikes have really come into their own in the last couple of years. Thanks to advances in electric bike motors and batteries. A couple of bike manufacturers, most notably Specialized, are making their own electric bike motors. The vast majority of bike companies are using the same motors. So, you will find exactly the same electric motor being used on bikes from different brands and at different price points. In this guide, we’ll take you through the main types of electric bike motors. Look at the differences between the most commonly used brands.
Electric Bike Hub Motors vs Mid-Drive Motors
Electric bikes tend to either come with a hub motor or a mid-drive motor. Mid-drive motors sit where the cranks and bottom bracket are on a bike and drive the cranks and chain around. Hub drive motors sit in the middle of the wheel and drive the wheel directly. Hub drive electric bikes are cheaper but less efficient, and less smooth, to ride.

Trek Electric Bike Range Guide
The Trek electric bike range has been pretty enormous at times. This has mainly been due to a single model of bike being available in multiple battery and colour variations so you quickly ended up with dozens of variants. Thankfully Trek have scaled this back a little recently, and their electric bike range is now easier to understand.
Until recently nearly all Trek electric bikes came with Bosch motors. For the 2023 season they are continuing with Bosch but also introducing motors from new brands like TQ and Hydrive on selected models.

Trek made their first bikes in 1976 in a barn in Wisconsin. Now they’re one of the biggest bike brands in the world. Trek bikes cover everything from professional-level road and mountain bike race bikes to commuters, hybrids and kids bikes. There is a strong heritage of racing at Trek and many Trek bikes have a strong race influence. They take a very scientific approach to researching bike and human performance and then make the fastest and most efficient bikes they can.
It doesn’t stop their attention and passion for cycling flows through everything they do. Since the 1990s, Trek has supported Places for Bikes. Places for Bikes is an advocacy organisation in the USA that gets more people on bikes more often! Places for Bikes ethos falls in line with the companies mission statement to:
