The Mega has been the best selling bike in Nukeproof’s range for over 10 years, and as soon as you swing a leg over one it’s easy to see why. 

Like the trusty Range Rover, the Mega is a case study in evolution over revolution, with the frame, geometry and suspension kinematics being tweaked over the years. The end result of this careful design evolution is that the Mega is one of the easiest bikes to get on and go fast, perfect for its intended purpose of enduro racing, where long stages and limited practice make riding sections blind a common occurrence.

For this latest version of the iconic enduro bike, the suspension has been tweaked from the previous version to make it more supple off the top while still giving excellent bottom out resistance. Other changes include tube-in-tube internal cable routing on the carbon frame and the ability to hold a 750ml bottle inside the front triangle.

If you’re looking for an enduro bike backed up by years of racing pedigree, look no further.
