Snow bikes have been around for decades, however the sport has only taken off properly in the last few seasons as the likes of Canadian Reagan Sieg break new ground.

The limits of what humans and machines can achieve are being pushed ever further with mountain biker Darren Berrecloth and Australian stunt rider Robbie Maddisonkeen to explore this daredevil world in a new four-part video series called "Powder Hounds".

Maddison joined Sieg, Ronnie Renner and Brett Blaser in central Idaho for the first part of his education.

"This is an opportunity for me to test new boundaries - a new facet of the sport,” Maddison said.

"Idaho is the birthplace of snow biking.

“Big steep stuff and places people have never seen."

Berrecloth and Brock Buttars then joined the fun in British Columbia where they carved out even bigger, gnarlier lines on stunning, newly explored terrain.
