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.

The Walkthrough

2019 Powerfly FS

favorite_borderWhy 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

Sizing & fit

The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
