Trek 2025 Fuel EXe 9.9 XX AXS T-Type

The Fuel EXe 9.9 XX AXS is mountain biking elevated. It rolls into untouched terrain that lies between traditional mountain bikes and electric bikes with new technology that silently blends in with nature and the finest components the industry offers. From its light and stiff carbon frame and wheels to a tiny but mighty TQ transmission, the EXe 9.9 is eager to rally any trail. It spares no expense, with a SRAM XX AXS transmission that's as light as it is precise, and it's loaded with an ultimate RockShox suspension package and TyreWiz to keep your setup dialled

You have expensive taste and don't want to sacrifice performance for anything. You want a bike that not only rallies the mountain top to bottom, but looks damn good doing it. From the carbon frame and wheels to fully a wireless SRAM XX transmission, you'll get a bike built with meticulous care and attention to detail, while the space-age TQ motor quietly assists you back to the top so you can take on lap after lap of singletrack.

An OCLV Mountain Carbon frame with a fully-encased 360 Wh battery and space-age TQ harmonic pin ring transmission with a smart charging port, integrated LED display and discreet handlebar remote. 150 mm of RockShox Lyrik Ultimate fork, DebonAir spring, Charger 3 RC2 damper and 140 mm of RockShox Super Deluxe Ultimate rear suspension. Plus, light and stiff carbon wheels set up tubeless, TyreWiz and SRAM's XX AXS wireless electronic direct-mount transmission that's built, light, tough and shifts cleanly, even under load.

The Fuel EXe 9.9 takes mountain biking to the next level with industry-changing technology from the quiet-and-compact TQ transmission to the meticulously laid carbon frame. It's the best of both worlds - it rallies the trail like a traditional bike on descents but rips back to the top with natural assist on climbs. And what's more, it's fully equipped with a treasure trove of components, like the upgraded RockShox suspe

TQ-HPR50 - small, quiet, mighty
The TQ-HPR50 motor is super-efficient with an amazing power-to-weight ratio. Most motors use gears and belts that take up space and can make noise or break. The TQ-HPR50 uses a harmonic pin-ring drive transmission that's small, ultra-quiet and unbelievably natural-feeling.

Range Extender
Give yourself 40% more range with an optional 160 Wh external battery. It fits in a standard bottle cage and doesn't require any complicated wiring or special mounts.

Connect, customise, calculate
The Trek Central app seamlessly connects with your bike for custom motor tuning, activity tracking and more ways to analyse and personalise your ride. You even get navigation features and real-time range calculations.

Removable battery
The 360 Wh battery gives you power for 2-5 hours. It's concealed in the downtube, but it's still easy to remove for more convenient charging.

Active Braking Pivot
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.

Transition to transmission
The SRAM Eagle T-Type transmission mounts directly to the frame, skipping that pesky derailleur hanger of yesteryear. This makes for a more robust system that's not only cleaner-looking, it's also more precise under load and easier to set up.
