It's probably testimony to the daring lifestyle that BMX rider Jason Phelan has led so far that when asked about his latest stunt, he is seriously considering the possibility of sharks.

"Do you think there will be any out there?" he asks hopefully. "I've been told you get sharks off the west coast of Scotland."

For this daredevil rider sharks are merely a bonus, especially when you've outgrown doing stunts on land and decide to take your bike out on to the water instead.

The BMX heavyweight is teaming up with Scotland's deep sea divers from the Professional Diving Academy in Dunoon, Argyll and Bute, to create what he calls an "epic playground" for his BMX, both on board and underwater around their diving boats.

"To be honest, I'm not entirely sure I can swim either," he says with a laugh.

"I've got my armbands though, so I'm sure I'll be fine. Plus the divers can just whisk me out if I don't bob to the surface again."

Irish-born Jason, whose stunts led to him having a signature pro frame named after him, plans to build a series of ramps, ropes and obstacles on diving boats The Fleet and The Thora, making good use of some underwater filming to bring his dream stunt to life.

"I can't give too much away because I want it to be a surprise but we plan on heading out there to shoot everything in June," Jason says.

"I got in contact with the diving academy and they were super keen. It's not every day a professional diving academy says sure, come on board, but the guy who runs it has an Irish surname so I think that kind of counted in my favour."

Jason is a regular sight among Glasgow's elite stunt bikers, who include professional street trials rider Danny MacAskill, who has already publicly backed his mate's sea mission.

The team will head out from Dunoon into the waters of Holy Loch with pontoons loaded with ramps, camera kit and, of course, a BMX.

"It is a bit of an epic task but we're seriously in the best location ever. The whole area is fantastic," says Jason, who has been based in Glasgow for the last 10 years.

"It's pretty crazy and pretty surreal. It's driving me nuts so I need to bring it to life."

Described by Ride UK as a "BMX riding machine", Jason has been given full permission to create his perfect land set at sea, though this won't be the first time hen has taken a bit of a dunking in the name of extreme sport.

One of his stunts last year, which featured him riding headlong off a pier, has been viewed close to 190,000 times.

"Over the last few years I always seem to send myself into the sea so this idea kind of grew out of that," says Jason.

"My main plan is to ride and perform tricks between the two boats with some extra surprises thrown in."

As for the risks involved, sharks aside, Jason is unsurprisingly as fearless as you would expect. In fact, all he does is laugh at the idea that there might be any.

His full-throttle riding style has sometimes got him into difficulty in the past. In 2013, he broke two ribs when attempting to do a backflip off of a self-built rail and suffered from what he describes as "a wee bit of memory loss".

"Yeah, that was a bit crazy," he admits. Not that a few previously broken ribs could ever stop this adventure addict from attempting his dream stunt.

"Usually I'm just out riding on the streets of Glasgow, at the Unit 23 skatepark, or up at Loch Lomond, which I love," he says.

"I recently turned 30, so I guess you could say I'm trying to make the dream come alive before I get too old.

"Stay tuned - it's going to be epic."
