With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

NukeProof Mega 290 29er Carbon Mountain Bike Frame 2021 Yellow

Season : 2021

Brand : Nukeproof

Code : 21-MEG-290-CRB-FRM-YEL


The Nukeproof Mega; 2017, 2018 (x2) & 2019 World Enduro Champion under the control of Sam Hill and Elliott Heap (u21 World Champion 2018), a top 10 at Downhill World Championships and a 4x Wold Championship Silver Medal make for an impressive C.V. These titles, along with a host of national titles, race wins, media awards and accolades make any changes to this design a difficult act to follow.

As a thoroughbred, the Nukeproof Mega has been subject to constant evolution as it is tweaked again and again in search for those marginal gains for ultimate performance. However, after several years of this process, the ultimate performance of the V3 Mega platform was starting to be reach it’s limitations. In order to go to the next level and implement some new theory, a fresh start was needed, please welcome the all new Mk. 4 Nukeproof Mega.


Nukeproof frames always started from the basis of the kinematic design. The R&D team work with key athletes and their own experience to decide on the key ride characteristics. From there pivot points are plotted onto a framework and handed to the product designer to apply the aesthetics. Enrique Repolles has been with Nukeproof since the reincarnation of the brand. He has penned almost all the bikes and components you have seen from us and the V4 was no exception. When the V4 project started there were a number of design ideas that went into the melting pot. However, there were only two things that the whole team could agree on;
  • It had to look like a Mega
  • It had to fit a water bottle, with no compromise to performance
In order to do this, the Nukeproof team went back to look at each iteration over the ten-year history of the Mega, taking inspiration from the best features whilst adding a modern twist.
