Extreme sports are not everyone's cup of tea and bungee jumping is certainly not for the faint-hearted. So what drove disabled daredevil Riley Martin to do just that ?

The brave 21 year old from Canada doesn't shy away from much and certainly does not let his wheelchair hold him back. SO a couple of weeks ago he dropped 170 feet over a swollen river in Canada to the amazement of onlookers. Riley claims he was mainly inspired to take the vertigo-inducing jump last month having seen Canadian paralympian Rick Hanse doing the same.

During a week end break with his partner in British Columbia Riley and his self propelled wheelchair where strapped in to a harness by the event organisers. Reilly who confesses to being nervous and can be seen in the video as he makes the 170 foot plunge over the Canadian river.
