It's right for you if...
You've seen the e-bike light and want to expand your boundaries. Like us, you believe that nothing should stand between you and your next great ride, including big climbs, headwinds and rugged trails you wouldn't otherwise be able to explore.
The tech you get
A lightweight and durable aluminium frame that fully encases a 625 Wh battery for sleek looks and protection on the trail, a Bosch Performance CX (250 W, 85 Nm) motor that assists up to 25 km/h and an ergonomic Bosch Purion controller. A RockShox Recon RL fork with 120 mm (XS: 80 mm) of travel and a SRAM 1x12 drive train. Bontrager Kovee Comp 23 tubeless-ready wheels.
The final word
With Powerfly 5, you get parts upgrades that make a big difference riding off-road, like an air-spring fork that's smooth and adjustable for your own weight, plus more powerful 4-piston brakes and wheels that make it easy to ditch the tubes for better traction and flat protection.
The Walkthrough
favorite_borderWhy you'll love it
- The new, better-than-ever Bosch motor is smaller, lighter and more efficient. It feels more natural while you’re pedalling, and has less drag when you’re not
- 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
- The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
- The SRAM Eagle drive train gives you a lot of gears and a wider gear range, so you can always find the right cadence for getting the most out of the motor
- You can boost your Powerfly’s utility by adding a rack and mudguards, plus built-in wiring lets you easily install lights powered by the motor
Features
Will my bike have a curved top tube?
Smaller frames (S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. The larger frames (M and ML) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
New Bosch Performance Line CX
The all-new Bosch Performance Line CX motor is lighter, smaller and quieter than previous versions, for cleaner integration and more nimble handling. It’s also more efficient so you can go further on a single battery charge. Use the intelligent eMTB mode to automatically adjust the amount of assist to match the terrain. It’s a set-and-forget mode that delivers just the right amount of power so you can focus on enjoying the ride.
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.
Motor Armor
This unique protection shield is lightweight yet robust, and protects the motor from rocks, logs and other trail debris.
Rack mounts
Going for a long ride? Rack mounts make carrying accessories a breeze.
Lighting ready
The bike is already internally wired to accept additional lights. Go to your dealer and simply have them attached to the bike and plug them in.
Smart Wheel Size
The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.
Alpha Platinum Aluminium
Our premium lightweight aluminium is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.
Rear kickstand mount
Chainstay mounts make it easy to install a rear kickstand that stays out of your way and supports bikes of all sizes. No more laying or leaning.
