Powerfly FS 5

Model 23256

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.

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.

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.

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.

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
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
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

"It's nice to have a dropper post, fully-adjustable suspension, and a frame that is well-balanced. The drive system is positioned well and performs incredibly. Trek really dialed in their rear suspension and ABP reduces skipping so the rear wheel track the ground. The removable battery pack with a handle makes this an easy bike to lift, transport, service on the trail, and park securely."

"On terrain that an elite-level XC racer would struggle to conquer, the Powerfly winched up huge mountains with seamless power delivery, especially in eMTB mode that automatically matches your effort. Planted and sure-footed on the descents, it gives you the confidence to release your grip on the powerful brakes and push the tires to the limit."

"The eMTB mode is a fantastic alternative to the manually adjusted power settings found on most other e-bikes. The beauty is that eMTB mode works so well, you can forget about it entirely and focus on the ride instead. Having e-bike specific forks and four piston brakes for example is something that seems obvious, but surprisingly few companies actually make happen."

RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It’s the most convenient way to remove your battery for transport, security, or just easier charging.

Our patented Active Braking Pivot allows your suspension to work freely whether you’re on the brakes or off. It’s smooth, controlled suspension that’s at its best all the time.

Bosch’s Performance CX line is made for rugged off-road use with a maximum torque of up to 75 newton meters, sustained power into the high cadence range for sporty acceleration, and a sleek mid-mount motor for ideal weight balance and obstacle clearance.

Bosch's Purion display features a fully-functional speedometer with a backlit display, service interval indicator, and battery range indicator. Its thoughtful design allows riders to scroll through functions or choose the right level of support while maintaining contact with handlebars.

This unique protection-shield made of lightweight but robust aluminum protects the motor against stones.

Our premium lightweight aluminum is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.

Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.

We reserve the right to make changes to the product information contained on this site at any time without notice, including with respect to equipment, specifications, models, colors, and materials.

Bike and frame weights are based off Trek pre-production painted frames at time of publication. Weights may vary in final production.

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.
