A lighter bike is one that's better to ride. That's the reason for the Nature's double-butted aluminium tubes, which reduce weight without sacrificing strength or durability. Clearance for tyres up to 50mm wide allows for a more comfortable ride and a tapered head tube ensures precise steering. Sleek luggage carrier and mudguard mounting points and Smooth Welding frame joints complement the frame's good looks and make it easy to upgrade to suit your needs. You can rest assured that, as with all our frames, the Nature has passed all our stringent in-house safety tests. It's in it for the long haul.
