Cyclists who rode Boris bike up Ventoux conquer Mount Washington on NYC Citibike (video)

Following last summer's ascent of the Giant of Provence, the group flew to New York to hire a Citibike and take it up America's iconic Mount Washington

Last year, three friends became YouTube stars when they took out a Barclays Hire Bike from a docking station in London, drove it 700 miles to the foot of Mont Ventoux in southern France, rode it to the peak, and got it back to a London docking station before the 24-hour maximum usage time was up.

Thanks to the support of viewers, Rob Holden, Ian Laurie and Matt Winstone were able raise more that £20,000 for Macmillan Cancer Support and other charities.

This summer, they upped the ante and decided to travel to New York, where a similar hire scheme is in place, which uses the same spec bikes as London.

In a relatively short window of 36 hours, the hire bike fanatics flew from London to New York, hired a Citibike from a docking station and drove it 400 miles to New Hampshire’s Mount Washington. They conquered the 7.5 mile (12km) climb, which averages 12.5% and has ramps of 14-22%,  before returning the bike and flying home.

This time, as well as Macmillan, money is being raised for the Livestrong Foundation. Both charities work to improve the lives of people affected by cancer.

The trip wasn’t without its logistical challenges, including an armed hold-up by the NYPD who thought the team had stolen the bike, and the climb was ridden in near-30 degree heat.

Despite the heat and the gruelling gradient, Holden completed the ride in 2 hours 10 minutes.
