Trek Powerfly 4 625Wh Electric Hardtail Mountain Bike 2024 in Grey Pearl/Lithium Grey

Season:2024

Brand:Trek

Code:41036PRL

The Powerfly 4 625 takes Trek's most affordable electric mountain bike and gives it a boost with a longer-range 625 watt-hour battery. Of course, you still get the 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.

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 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.

This model gives you a longer range battery than the standard Powerfly 4, so you’ll never be short on fun.

Please Note: Sizes S and XS are provided with a curved top tube for improved stand-over height.
