Powerfly FS 5 is a versatile, confidence-inspiring, full suspension electric mountain bike. This 130mm full suspension trail bike has the extra boost of a powerful Bosch motor, a trail-tough Shimano drivetrain, and a durable Alpha Platinum Aluminum frame with Removable Integrated Battery (RIB) for better balance on the trail, great looks, and exceptional ease of use.
It's right for you if...
You want to bring more capability to your mountain biking in the form of a high-performance pedal-assist system. You know an e-bike can change your life and you want the plush ride of a full suspension mountain bike that will stand up to more rugged and technical trails.
The tech you get
A durable Alpha Platinum Aluminum frame that fully encases a long-range 500Wh battery for great aesthetics and ride quality on the trail, a Bosch Performance CX motor and an ergonomic Purion controller. Plus, 130mm front and rear travel with a RockShox Recon RL fork, Tubeless Ready Bontrager Kovee 23 rims, and a 10-speed Shimano Deore drivetrain.
The final word
This bike pairs electric-assist performance with singletrack trail capability. It's a fun, forgiving, full suspension ride that can help you reach new destinations on rugged trails with pedal-assist of up to 20 mph.
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 - For e-MTB, full suspension is a game-changer: it soaks up rugged terrain so you can ride the Bosch pedal-assist system to its full potential
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
