Trek (USA) – Press Release: Powerfly LT 9.9 is a carbon full suspension electric mountain bike with the highest-level parts and suspension spec in the line-up. Incredible design, extraordinary capability and a no-compromise components package that includes carbon wheels and SRAM's flagship Eagle drivetrain put Powerfly LT 9.9 in a class of its own.

It's right for you if...
You're looking for the highest-end e-MTB for the highest-end adventures. Sleek and rugged. Light and tough. Hard-working and fun. If this bike seems like a contradiction, it's because it breaks the rules and demolishes boundaries – including whatever limit you've set for your riding.

The tech you get:
A lightweight and trail-tough OCLV Mountain Carbon main frame that fully encases a long-range 500 Wh battery for great aesthetics and protection on the trail, a Bosch Performance CX motor and a Purion controller. Plus, an e-bike optimised FOX Factory 36 fork with thicker, stiffer, legs and a RE:aktiv shock, grippy 27.5+ mid-fat tyres, Bontrager Line Pro 40 carbon wheels with a 108-tooth Rapid Drive hub for instant engagement, a Bontrager Line dropper post, a 1x12 SRAM XX1 Eagle drivetrain and 4-piston hydraulic disc brakes.

The final word:
No compromises. Powerfly LT 9.9 brings the highest-quality trail bike parts and a powerful Bosch pedal-assist system to a lightweight OCLV Mountain Carbon frame to make performance ride that has one purpose: to give you the greatest trail adventures ever.

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
OCLV Mountain Carbon main frame with alloy stays make for a bike that's light and trail-tough, 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
