It's right for you if...
You're sold on the e-bike revolution and want the capability and versatility of a mountain bike at a price that doesn't resemble the car you're trying to use less. You want bigger, better trail adventures and know that an e-MTB with the latest user-friendly tech is the best way to get them.
The tech you get
A lightweight and durable Alpha Platinum Aluminium frame that fully encases a long-range 500 Wh battery for sleek looks and protection on the trail, a Bosch Performance CX (250 W, 75 Nm) motor that assists up to 25 km/h, an ergonomic Bosch Purion controller, a Shimano drive train, a 120 mm SR Suntour XCR fork with lockout and hydraulic disc brakes. Plus, Smart Wheel Sizing means you'll get the fastest wheel that fits – 29˝ wheels on larger frames, 27.5˝ wheels on smaller frames.
The final word
Our most affordable electric mountain bike is equipped with performance parts, a high-end Bosch motor, powerful battery and intuitive controller for confidence and a fun boost on trails and roads.
favorite_borderWhy you'll love it
- 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
- This bike expands boundaries: the top-notch Bosch system is equally suited to commuting, recreation and a ridiculously fun time on the trails
- The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
- It's equipped with an external charging port for easy charging on or off the bike
- It rides like a trail bike because it is one: Powerfly is built according to Trek's trail heritage with mountain bike tech developed over decades of innovation
Bosch Performance Line CX
Bosch's Performance Line CX motor is made specifically for off-road use with more torque and power for better acceleration. The intelligent eMTB mode automatically adjusts the amount of assist to match the terrain. It's a set-and-forget mode that delivers just the right amount of power. You get optimum control, traction and battery life so you can focus on enjoying the ride.
Removable Integrated Battery
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.
Bosch Purion Display
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 the handlebars.
Smart Wheel Size
The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.
This unique protection shield made of lightweight but robust aluminium protects the motor against stones.
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.
Going for a long ride? Rack mounts make carrying accessories a breeze.
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.
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 at the back lets you run wider tyres and a larger chain ring without affecting q-factor and pedalling efficiency.
