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

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.
