Fuel EXe 9.9 XX AXS T-Type: Master the Trails with Precision

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.

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 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.

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.

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.
