Here's our selection of the best videos from the world of two wheels

The first Grand Tour has started in the shape of the Giro d’Italia. So far, only Orica-GreenEdge riders have worn the pink jersey.

At the same time, the Tour of California is underway and after two wins out of two Mark Cavendish had to concede his leader’s jersey on a hiller stage three.

To break-up the stream of professional cycling footage in this edition of videos of the week, there’s also a bit of headcam footage demonstrating the need for patience and for people to share the road.

Will a future 4X champion be Italian?

No need for pedals here: these young racers show us what balance bikes were really made for when they hurtle their way around a pump track. Fearless and skilled, there must be a future champion or two in there.

The best of Spin London

Close call on a rat run road

This could have been so much worse, and thankfully wasn’t, but does indicate a need for all road users to exercise patience and caution on busy roads.

The parked cars make it necessary for cyclists to take the primary position to avoid being doored, and with a cyclist going in either direction it would certainly pay for the oncoming vehicle to hang back before passing.

Back on stage two there was a new entry into the list of worst fan fails. As can be seen in this video, it looks like a spectator on a bike attempted to join the fast moving peloton, with an obvious and unfortunate outcome.

Just celebrating the pink jersey. Honest.

He’s not the first to make this mistake, but he is certainly the most adamant that no mistake was made. Cannondale-Garmin’s Davide Formolo had already won the stage from a well timed solo break, meaning Simon Clarke was sprinting for second.

He is clearly ecstatic about the win, until Giovanni Visconti delivers the bad news. In the interview that followed, Clarke assures the audience that he was simply celebrating keeping the pink jersey in Australian hands. Ok, Si.

Mark Cavendish was back on top in the battle of the sprinters after winning the opening two stages of the Tour of California. But on stage three his lead was lost as the road went upwards.

Toms Skujins of the Hincapie Racing Team – a US based continental squad – rode away on his own and kept a high calibre chase group at bay to take the stage by over a minute. This moved him into the the overall lead by 32 seconds over Peter Sagan.
