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.

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 500 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.
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.
All Terrain Cycles are now offering a Home Delivery service.
Our Cytech qualified mechanics will first make sure that your bike is fully checked and ready to ride.
Then we will deliver it completely assembled direct to your home or place of work where we will set up your bike for your personal needs and answer any questions you may have. All for just £50.00.
Our delivery map indicates a general area, however, if you do not see your location on the map please call us on 01274 588488 to discuss a special delivery.
After the first few weeks of use, the whole bike will settle down. As a result, the gears may need tweaking, some nuts and bolts may need tightening and you may well need to check the adjustment of the saddle and handlebars.
One of our Cytech qualified mechanics will hand build your bike leaving only a few minor adjustments for you to do once your new bike arrives. Our mechanic will also complete a rigorous Pre-Delivery Inspection (PDI) before carefully re-packing for shipping to you; but in order to fit the bike back into its box for delivery, some disassembly has to be done. Re-assembly of these parts should be straightforward and should not take very long.
