It's a tough job ( sob sob) for us tech editors at Pinkbike to test a bike from the lower echelons of the bike world. The Bossnut is also very well specced for the money and comparable to bikes much higher in price so it could be treated as a new bike but the same capability and spec of used bike.

The age old question, it’s up to the individual I suppose, but there is something nice about having a brand new bike with everything working at once, I’ve built many a bike when upgrading the frame with all sorts of horror stories. Why would a rider choose the Bossnut over a well maintained, used bike of a similar price? Honestly, I started this project with fairly new or returning riders in mind, but the first Bossnut quickly surpassed that so with the ‘V2’ I wanted to upgrade the frame with things like the increased reach, shorter stem, and increased tyre spacing so they could be ridden at UK enduros or the Alps etc.

What type of rider is the Bossnut aimed at? Once I had this a test bike was built and ridden in the Peak (UK) by a few of us and we tested several different shock tunes and then the rest is history as they say. Then on the opposite of this, I looked at what was out at the price point I wanted to hit and not seeing geometry or spec that I felt would give riders the best ride or time on their bike. Really it came from riding bikes like these, reading reviews and seeing the direction of the market.

How did you decide upon the geometry numbers for this bike? It looks like the Bossnut is lining itself up against some big sellers like the Specialized Stumpjumper, Trek Fuel and Giant Trance?
