Chris Froome became Britain's first three-time winner of the Tour de France when he crossed the finish line of the 21-stage race in Paris on Sunday. The Team Sky rider, who won the 2013 and 2015 races, is the first man to defend his title in more than 20 years. He finished arm-in-arm with his team-mates behind the peloton after Andre Greipel won the final sprint finish.

So, it was a trouble-free day for Chris Froome in the end, with his closest rivals deciding to consolidate their podium spots rather than the attack the man in yellow. The spills of yesterday’s stage were avoided, Team Sky controlling a tentative peloton over four climbs and slippery descents. The race was, in truth, won before today, and in far more testing circumstances – Froome has experienced his fair share of drama on the road here, and will cross the line in Paris a worthy winner. I’ll leave you with our race report. Thanks for joining me. Bye!

Paris has inaugurated its first bike highway. Opening last May, the 0.5-mile stretch of freshly paved road alongside the Bassin de l’Arsenal is part of the Réseau express vélo (“REVe”), an initiative to build fast-track bike lanes free of motorized vehicles. It’s only the first section of the soon-to-be 28-mile network of bike highways that will cross the city by 2020. In 2015, the city voted unanimously to spend €150 million ($164.5 million) on expanding and improving its biking infrastructure, including REVe (which translates to “dream” in French).

How much energy does it take to move a human from point A to point B? Ever wondered what the most energy efficient way to do this is? In a head to head contest on energy efficiency how would the Telsa Model 3 compare to a electric commuter bike?

Wheels have long been a sign of economic status for both individuals and nations, and on the lightly trafficked streets of Pyongyang, capital of impoverished and isolated North Korea, electric bicycles are the hottest new ride on the road. Almost unseen two years ago, the Chinese-made two-wheelers are a common site this week in the city, which hosts the first congress of the country's ruling Workers' Party in 36 years.

It really must be heaven to be a cyclist in Denmark. You get lovely, dedicated infrastructure, like this new bridge. You get cities that run analyses showing how bikes are good for people, and cars aren't. And now, if you live in Aarhus, you can get a special tag to help beat the traffic lights. Aarhus, Denmark's second largest city, is currently running a trial where cyclists are given RFID tags that they attach to their wheels.
