Hi, can anyone recommend a hard trail mountain bike for under £500 I have been looking online and found bh spike 6.1 http://m.gooutdoors.co.uk/bh-bikes-spike-6-1-29er-mountain-bike-p343626 and the specialized pitch sport http://m.evanscycles.com/products/specialized/pitch-sport-2015-650b-mountain-bike-ec070611. Can anyone recommend anything or give any advice? Thanks
