Quite a broad brief there TBH Alex. Do you want hardtail or full sus? (I’m guessing fully rigid is not your thing). I’m not too good with full sus, but i’m sure someone will be along shortly to give you some ideas. If its a hardtail you’re after, I like the Genesis range. Do you want steel or aluminium? I have a Latitude, great all-rounder, comfy all day bike, but quick on single tracks, climbs and descends well. It seems to take all the abuse I throw at it, but i’m not rad to the max! You may want something a bit burlier depending on how hard a beating you want it to take. A friend of mine has the Orange Crush. its quite a lot beefier, a bit heavier, nice bike though – he thoroughly enjoys it. Test ride as many as you can.
