The Nukeproof Mega is an enduro bike built on the tenets of balance, predictability, and absolute speed. Originally conceived as the downhiller’s trail bike, it was purpose-built to conquer the legendary MEGAVALANCHE race in France and spawned a new category of bike that would be known as Enduro forever more .
Over the past decade, the Mega has earned its reputation as a race-winning machine — with multiple Enduro World Series stage wins and four overall EWS titles to its name. It’s the evolution of relentless development and refinement, shaped by the feedback of world-class racers and dedicated riders alike.
Now in its fourth generation, every detail of the Mega has been optimised for speed, control, and efficiency — built to go flat-out, wherever the trail leads.

Bought the Nukeproof Mega from Wheelie and the service was exceptional. Bike arrived perfectly built and ready to ride. The team really know their stuff.
Couldn't fault the experience. Great price, fast delivery, and the bike was impeccably set up. Would 100% buy from Wheelie again.
Really helpful team who helped me choose the right size. Came in for a test ride and bought the same day. The workshop setup is top notch.
