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, 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 equipped with AirWiz technology to keep your setup dialed just to your liking.
It's right for you if...
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.
The tech you get
An OCLV Mountain Carbon frame with a fully-encased 360Wh battery, and space-age TQ harmonic pin ring transmission with a smart charging port, integrated LED display, and discreet handlebar remote. 150mm of RockShox Lyrik Ultimate fork with AirWiz, DebonAir spring, Charger 3 RC2 damper, and 140mm of RockShox Super Deluxe Ultimate rear suspension. Plus, light and stiff carbon wheels set up tubeless, and SRAM's XX AXS wireless electronic direct-mount transmission that's built, light, tough, and shifts clean, even under load.
The final word
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 suspension package with AirWiz, and a fully wireless SRAM XX AXS transmission.

TQ-HPR50 - small, quiet, mighty
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.
Give yourself 40% more range with an optional 160wh external battery. It fits in a standard bottle cage and doesn’t require any complicated wiring or special mounts.
Connect, customize, calculate
The Trek Central app seamlessly connects with your bike for custom motor tuning, activity tracking and more ways to analyze and personalize your ride. You even get navigation features and real-time range calculations.
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.
Transition to transmission
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.
RockShox AirWiz and Quarq TireWiz
TyreWiz monitors your tire pressure while AirWiz monitors your fork and shock pressure. Set your desired pressure in the SRAM AXS app and then just check the lights before each ride—red means you need a pump, green means go ride.
BITS: Your trailside savior
Cleverly integrated into the steerer tube, the included BITS multi-tool has everything you need for trailside adjustments and repairs.
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.
