I saw someone on one of these ellipitical bikes this morning in Great Missenden, it's a kind of cross trainer on wheels! It's so cool! And great if you have an injury (like spinal disk issue) and can't run... check out this video of one in action:

You can see some on sale here... http://www.elliptigo.co.uk/
Just a shame about the price.... but hopefully with popularity it might come down a bit! xx
