Trek Powerfly 4 625wh Gen 4 2024
The 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 simple to remove and install, plus all the other parts that make Powerfly 4 an ideal entry into the joys of riding a pedal-assist bike on or off-road.
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 off-road 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 tough yet refined aluminium frame that fully encases a long-range 625 Wh battery for sleek looks, a Bosch Performance Line CX (250 W, 85 Nm) motor that assists up to 20 mph (25 km/h in Europe), a Bosch Intuvia display with LED remote, a 1x9 Shimano CUES drivetrain and a suspension fork with lockout. Plus, Smart Wheel Sizing means that riders of every size get a great fit – 29˝ wheels on larger frames, 27.5˝ wheels on smaller frames.
