SARACEN KILI FLYER ELITE £3,499.99

It may not look any different, but Saracen have tweaked the geometry and boosted the back end of the Kili Flyer for a more aggressive 2018 feel. The shock tune has also been altered, and it gets all-weather Maxxis tyres, not sketchy summer WTB rubber, to lose some weight and underline its UK-proof design. Despite being one of the cheapest bikes on test, it has a carbon swingarm as well as mainframe, which makes it the lightest here by a big margin.
