Powerfly LT 7 is the full suspension electric mountain bike that introduces the e-MTB world to incredible trail bike capability. It brings together the Removable Integrated Battery (RIB) frame design with longer travel suspension and 27.5+ mid-fat wheels for serious capability on even the roughest trails. A 150mm shock, 160mm RockShox Yari RL fork, 11-speed Shimano drivetrain, and a durable trail spec will hold up on your wildest all-mountain adventures.
It's right for you if...
Serious trail bike suspension, the latest in e-MTB frame design, and a durable spec that will hold up to raucous all-mountain riding. These are the non-negotiables in your search for your next ride. You're going to ride on big trails with features and technical sections that demand the extra traction and stability of mid-fat tires.
The tech you get
A durable Alpha Platinum Aluminum frame that fully encases a long-range 500Wh battery for great aesthetics and protection on the trail, a Bosch Performance CX 250-watt motor that assists up to 20 mph, and an ergonomic Bosch Purion controller. Plus, a 150mm shock, 160mm RockShox Yari RL fork with an ultra-plush DebonAir spring, grippy 27.5+ mid-fat tires, Tubeless Line Comp 40 wheels with a 54-tooth Rapid Drive hub, a dropper post, and more powerful 4-piston hydraulic disc brakes.
The final word
Longer travel suspension, quality trail spec, and a powerful Bosch pedal-assist system make this an incredible e-MTB. But what brings it into the next realm is the Removable Integrated Battery (RIB) frame design, which is a major advancement in electric mountain bike engineering.
Why you'll love it
1 - 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 to remove the battery without tools, and lets you mount a water bottle cage—even on full suspension e-MTBs
2 - Longer travel suspension and 27.5+ mid-fat tires are the perfect combination for traction, stability, and capability on rough trails
3 - It rides like a mountain bike because it is one: it has the same frame and suspension tech we've refined in our decades-long trail heritage
