Powerfly LT 9 is the top-end alloy full-suspension electric mountain bike in the line-up. Longer travel 150 mm/160 mm suspension with Trek's exclusive RE:aktiv damper, a powerful Bosch pedal-assist system, 27.5+ mid-fat tyres for extra traction and capability, a wide-range 1x12 SRAM drivetrain and 4-piston brakes give Powerfly LT 9 true trail bike performance and the ability to go further, faster and bigger than you ever thought possible on an e-MTB.
It's right for you if...
You ride rugged trails, and you're ready to go further and faster than ever. You want the best trail bike capability, the latest in mountain bike and e-MTB tech and enough suspension to soak up the big hits and obstacles that you'll encounter.
The tech you get
A durable Alpha Platinum Aluminium frame that fully encases a long-range 500 Wh battery for great aesthetics and ride quality on the trail, a Bosch Performance CX motor and a Purion controller. Plus, an e-bike optimised FOX 36 fork with thicker, stiffer legs, RockShox rear shock with RE:aktiv damper, grippy 27.5+ mid-fat tyres, e-bike specific Powerline Comp 40 wheels with a 54-tooth Rapid Drive hub, a Bontrager Line dropper post and a 1x12 SRAM GX Eagle drivetrain.
The final word
This e-MTB checks all the boxes for rugged trail bike capability. It has high-end trail spec, long-travel suspension with advanced damper tech, upgraded Bontrager wheels and a powerful Bosch pedal-assist system. All together, this makes for a ridiculously capable performance ride that's the perfect companion for serious trail outings.
Why you'll love it
Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy remove the battery without tools and lets you mount a water bottle cage – even on full suspension e-MTBs
Longer travel suspension and 27.5+ mid-fat tyres are the perfect combination for traction, stability and capability on rough trails
An advanced spec including e-MTB-specific parts and Trek's RE:aktiv damper take this model to the next level
It rides like a mountain bike because it is one: it has the same frame and suspension tech that we've refined in our decades-long trail heritage
