The 2023 Trek Fuel EXe 9.8 XT Electric Mountain Bike is part of a new generation of lightweight electric mountain bikes which bridge the divide between pedal-assist and traditional bikes. It features a carbon frame and a compact motor that keeps the ride light, lively and quiet. The 9.8 is the third bike in the Fuel Exe range

The Fuel Exe is built around an OCLV Mountain Carbon frame with a fully encased 360 Wh battery, and TQ harmonic pin ring transmission. TQ are known for making motors for robots and space probes. The motor uses on the Fuel Exe has many fewer moving parts than a standard electric bike motor which makes it smaller, quieter, lighter and more reliable. The Fuel Exe comes with a smart charging port, integrated LED display and discreet handlebar remote. The charging port is positioned so you can easily attach a range extender battery which sits in your bottle cage.

The Fuel Exe 9.8 comes with a 150 mm RockShox Lyrik Select+ fork with DebonAir spring and Charger 2.1 RC damper, and 140 mm RockShox Super Deluxe Select+ rear suspension. All wrapped up with the precise shifting and modulation of a Shimano XT drivetrain.

This bike is perfect for

Mountain bikers who want the feel, ride (and noise) of a traditional acoustic bike with the added boost of a small, light and efficient TQ harmonic ring motor. With reliable RockShox suspension and quality Shimano parts this is a great trail ready package.

Key Features

  • It finds the perfect balance between a traditional and electric ride, with adaptive assist that disappears under you on climbs, and a nimble ride that feels natural and playful on descents
  • Its tiny-but-mighty TQ transmission is tuned for the trail, keeping things quiet so you can stay in the moment, plus it ramps up power with you for a natural ride feel
  • The smart charge port, sleek integrated display and discreet controls keep the bike looking and feeling like a traditional mountain bike
  • It keeps your ride silky smooth even when the trail gets rowdy thanks to the upgraded RockShox suspension package that offers 150 mm of front and 140 mm of rear travel
  • You'll be able to add on a range extender when you want a little extra fuel in the tank for big days on the bike

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.

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.
