Overview

It's right for you if...

High performance isn't enough—you want the best the industry has to offer. From the carbon frame and wheels to XTR drivetrain and titular RockShox suspension that soars over boulders and roots, you want a bike that's ready for it all, and will help you get back to the top to take on lap after lap with a whisper-quiet motor that feels nearly invisible under you.

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, and Charger 3 RC2 damper, and 140mm of RockShox Super Deluxe Ultimate rear suspension. Plus, light and stiff carbon wheels set up tubeless, and Shimano's finest XTR drivetrain.

The final word

Fuel EXe 9.9 is an e-bike that redefines categories and is spec'd to meet the needs of riders with top taste. It eases steep climbs without pulling you out of your element with a quiet and ultra-durable TQ transmission without looking like a bulky e-bike, and offers a wealth of cream-of-the-crop components, from the carbon wheels to Shimano's lightest and best performing XTR groupset.

2022 Gear of the Year

"This is the first time an e-bike has made my Gear of the Year list [...] in addition to being silent, the HPR50 motor feels frictionless while pedaling. The assistance comes on with a subtlety that makes it feel like you are a younger, fitter version of yourself with a tailwind at your back."

Editor's Choice

"The low-key, silent assist is just enough, keeping it riding like a real mountain bike but making the climbs less sucky. Don’t get me wrong, I love a good high-power eMTB, but I loved this bike, too. Trek’s Fuel EX’s handling is dialed, and this is merely an enhanced version of that. I tested the top model, but, fortunately, there are also mid-priced models that eschew some of the AirWiz(ardy) without giving up any of what makes this bike rad."
