NUKEPROOF Mega Alloy 297 / 290 2026

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.
