"That tiny harmonic pin ring drive unit is the golden goose of e-bike motors." Find out what Pinkbike had to say about the revolutionary motor at the heart of Fuel EXe.Read more
"Overall, the Trek Fuel EXe is a bike that ranked consistently well across the board when it came to performance on the trail. It does everything pretty darn well and would be a great jack of all trades lightweight eBike for those looking to have a mid-power eMTB for trail shredding fun."
"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."Read more
"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."Read more
"Simply put, nothing comes close to the Fuel EXe when you paint the picture of the mountain bike experience as a whole."Read more
"The Trek Fuel EXe is the bike (e or otherwise) that plenty of people have been waiting to see… Removes the final few issues that the e-curious crowd had."Read more
"The Fuel EXe is such a harmonious package that I got comfortable with it very quickly, and it wasn’t much longer before I was in love with this bike...I legitimately forgot that I was on an e-bike at times…it’s the most natural feeling motor I’ve yet ridden."Read more
"We have to call it as we see it and the Trek Fuel EXe just elevated the eMTB game."Read more
"The first impression was a unanimous 'Wow.' This is one of the few times that a bike exceeded expectations."Read more
"There are times when I am left amazed by something new and shiny, and that is the case with the Trek Fuel Exe...I might even go as far as to call it an engineering marvel."Read more

With 108 points of engagement, Rapid Drive gives you nearly instant acceleration instead of a clunky lag when you step on the pedals. You get smooth, immediate power to blast out of corners and hammer through the rough stuff. And that extra pedal ratchet adds control that can make all the difference when tackling a tricky climb.
Bigger is better. The oversized seat tube diameter gives more support and strength for longer travel droppers, and allows for more robust, durable internals that work faster.
