Designed to excel on the toughest enduro tracks, the gravity focused Nukeproof Mega will inspire confidence on the most technical descents whilst maintaining pedalling efficiency for all-day epics.


Since 1995, the infamous Megavalanche DH marathon race has been synonymous with big all-mountain riding. Starting at the highest point on Pic Blanc (3300m) above the village of Alpe D’Huez; it is seen as the pinnacle of mass start mountain bike racing around the world.

Originally conceived in 2009 as the perfect bike for this exact style of racing, the Nukeproof Mega was born. Now in its 4th evolution, the Mega should need no introduction. It has tasted success within multiple disciplines and has numerous national and international race wins to its name.

Designed to excel on the toughest enduro tracks, the gravity focused Mega will inspire confidence on the most technical descents whilst maintaining pedalling efficiency for all-day epics in the saddle.

Updated Sizing

With the demands of the Enduro World Series races progressing at a rapid rate, sizing and fit have become more critical than ever. As a result, Nukeproof have added a new Medium-Long size to the range for 2020. The seat tube length stays the same as the Medium, whilst the reach has grown to 452.5mm which sits exactly in the middle between a size Medium and a Large. With a total of 5 sizes now in the range (S, M, ML, L and XL), there should be a perfect size for everyone.

Tested and proven on the toughest of terrain and in the most varied conditions by Enduro World Series Winner Sam Hill, the 2020 Mega 275 sets out to tackle every ride with its trademark attitude.
