Powerfly 4 625
< Show All Variants >The Trek Powerfly 4 625 takes our most affordable electric mountain bike, and gives it a boost with a longer-range 625 watt-hour battery. Of course, you still get our user-friendly Removable Integrated Battery (RIB) system that's super easy to remove and reinstall, plus all the other parts that make Powerfly 4 your ideal entry into the joys of riding a pedal-assist bike on or off road.
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 off-road adventures, and know that an e-MTB with the latest user-friendly tech is the best way to get them.
You get a tough yet refined aluminium frame that fully encases a long-range 625 Wh battery for sleek looks, a Bosch Performance CX (250 W, 85 Nm) motor that assists up to 25 km/h, a Bosch Purion controller, 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.
The Trek Powerfly 4 625 gives you longer range battery than the standard Powerfly 4, so you’ll never be short on fun.
