A British man plans to complete the entire 3,360 kilometre route of the Tour de France in July atop a retro-style chopper bike.

With its small front wheel, big back wheel and high seat, the Raleigh-brand bike is great for popping wheelies, but less than ideal for covering long distances or ascending the Alps.

That has caused some to ask why Dave Sims, a U.K.-based personal trainer, plans to use a bike he admits is “very unforgiving on corners… and even in a straight line at speed.”

Sims writes that he is taking on the challenge to back up his “coaching ethos,” that any person can reach his or her “maximum potential” on “any bike.”

"Without me the bike is NOTHING,” he explains on his website.

The website also contains links to donate money and a blog.

The most recent blog post said Sims will spend the final three weeks before the race focused on “climbing.”

He may need the practice: seven of this year’s 21 day-long stages are on mountains, five of which finish at a summit.

The 102nd Tour de France runs from July 4-26 and starts in Utrecht, Netherlands.
