Earlier this year six-time Olympic champion Sir Chris Hoy announced plans to cycle across Antarctica and travelled to Reykjavik in Iceland two weeks ago to train and test equipment.
Now he has taken to twitter to post teasers of himself getting to grips with the bike that he will be using on his adventure.
In one video Hoy can be seen doing a wheelie on a fat bike – an off-road bicycle with oversized tires, designed for low ground pressure to ride on soft unstable terrain, such as snow. While another posted shows the Scot riding on the snow with a ski attached to the bottom of the front wheel.

The 10-second clip shows the Olympian pedalling hard on the snow with the back wheel sliding from side to side, while the front wheel supported by a green ski, keeps him stable and upright.
Hoy announced his plans to cycle to the South Pole when he appeared on the BBC motoring show Top Gear earlier this year.
He will follow in the footsteps of American Daniel Burton, who was the first person to travel from the coast of Antarctica to the South Pole by bicycle setting off on December 2nd 2013 and arrived at the South Pole on January 21st 2014, travelling some 775 miles by bike.
While in 2012, former BBC Blue Peter presenter Helen Skelton became the first person to reach the South Pole using a bicycle, although her journey also consisted of using cross-country skiing and kite skiing – biking a distance of only 103 miles.
