Powerfly 4 is our most affordable electric mountain bike. It's built with parts that hold up, like a smooth-shifting Shimano drive train, and a powerful Bosch motor. Plus, it features our user-friendly Removable Integrated Battery (RIB) system that's fully encased in the frame yet doesn't require tools for removal. This bike expands your boundaries and lets you travel to destinations that you never thought you'd reach on a mountain bike.

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 off-road adventures, and know that an e-MTB with the latest user-friendly tech is the best way to get them.

A tough yet refined aluminium frame that fully encases a 500 Wh battery for sleek looks. The latest from Bosch with smart system Performance Line CX motor capable of speeds up to 20 mph (25 km/h in Europe), including the new Bluetooth® LED remote for easy connectivity and all-in-one navigation and activity tracking through the eBike Flow app. A 1x10 Shimano drivetrain and a suspension fork with lockout. Plus, Smart Wheel Sizing means riders of every size get a great fit – 29˝ wheels on larger frames, 27.5˝ wheels on smaller frames.

Our most affordable electric mountain bike comes with the same powerful Bosch motor and intuitive controller as our most expensive e-bikes, with a smaller battery and parts chosen to give you great value.

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 top-notch new Bosch smart system gives you more control over your ride with navigation and activity tracking through the eBike Flow app
It comes equipped with Walk Assist and an intelligent e-MTB 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
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
