Unicycle $39.95 at Soldsmart
I have always wanted to try one of these but as I can not even ride hands free on a normal bike I am afraid of the number of visits to A&E I would have. But I reckon they would be a great way to get fit and this a really good price.
They have a range of models and colours it seems (39.95-49.95)
