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.
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 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.
Why you'll love it
The final word
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.
