Adaptable performance. | Trek Fuel+ Gen 2

Jan 2026

When Trek launched the all-new Fuel line last summer, I was eager to spend time on the Fuel LX, MX, and MLX configurations. I’ve spilled a lot of words about that bike here, here, and here, and it’s safe to say I’m fairly smitten with it. But Trek wasn’t content to just release perhaps the most adaptable trail bike of the year. They simultaneously announced a corresponding “+” line that takes the same geometry and features and slaps on TQ’s new HPR 60 motor and a 580 watt-hour battery. That means that you get the same absurdly adaptable platform, that’s easy to swap between a 145/150 millimeter 29er, the 150/160 millimeter mixed wheel bike I reviewed, or a 160/170 millimeter full 29-inch bike. And yes, the secret menu options are still available, although, as I’ll get into later, I actually prefer slightly different configurations with this bike than with the meat-powered version. Trek Fuel+ MX 9.8 Eagle 90 Gen 2, Travel: 150 mm (rear) 160 mm (front), Wheel Size: MX with full 29” capabilities, Size Tested: Large, Build Tested: 9.8 Eagle 90, Head Tube Angle: 64.2°, Motor: TQ HPR 60, Battery: 580 Wh, Measured Weight: 44.94 lbs (20.38 kg), MSRP: $10,199

Trek Fuel+ EX 8 Gen 2 e-MTB review

Oct 2025

Ditching the old Fuel EXe moniker to fit with a new range of super adjustable bikes, Trek’s Fuel+ EX nails its trail duties. Thanks to a class-leading suspension kinematic and a geometry that’s tough to moan about, the Fuel+ EX delivers an excellent trail character that’s fun, engaging, and lively, but capable beyond its means. Though the whole of its adjustability is a stretch for those short of coin, and it could do with stronger tyres.
