As British cyclist David Sims sees it, lots of people before him have raised money riding an adult bike. Not quite as common? Raising money for charity by riding a famous children's bike.

So Sims is doing just that. And now, this isn't your casual loop around the block: Sims is riding the Tour de France.

This summer, just before the real cycling race takes place, Sims will embark on his own tour of the French countryside, biking for the Help for Heroes charity, which provides support to soldiers wounded in Afghanistan.

Like professional cyclists on big-boy bikes, Sims will have a team helping him along the way. A friend will trail him in an RV to offer assistance throughout any obstacles he might face.

To withstand the ride, which will cover more than 2000 miles, Sims has had to make surprisingly few adjustments to his Raleigh Chopper. The bike will even feature the original, 1970s-era tires.

"The main I've changed is the seat post and the pedal arms as it was originally designed for kids," Sim tells the New York Post'. "And the wheels -- on the first part of the race through Northern France, there are a lot of sections of really terrible cobbles, so a guy made me some really strong wheels as I kept breaking spokes. I've also had to put slightly better brakes on as well."

Sim's bike is best-known in popular culture for its role on the family sitcom The Wonder Years, in which the protagonist Kevin Arnold uses his Chopper to impress his childhood crush, Winnie Cooper.

Sim believes he'll be able to climb even the steepest segments of the race on the children's bike, and may even go farther than the actual pro riders will in this year's Tour de France -- riding on a kid's bike, he said there will be times where he opts for less-trafficked roads.
