After completing month long cycling challenge Race Across America, British Heart Foundation ambassador Pippa Middleton has donated her signed bespoke bike to raise money for the charity.

The Dassi bike is set to attract bids from cycling fans and collectors to help research into heart disease, and is running until August 13 at http://stores.ebay.co.uk/British-Heart-Foundation-Shop. Middleton said 'I wanted to complete this challenge to help raise awareness of the importance of heart health. So whether you're inspired to get fit or you're a cycling fanatic wanting to add to your bike collection, take a look at my bike and put in a bid'.
