The cheery sight of Robin Williams on a bike, zooming around the Bay Area attired in bright spandex, is a fond memory of many — and now the public has a chance to own a piece of that joy.

Eighty-seven of the comedian's bikes, some very rare collectors items in their own right, are currently up for auction on Paddle8.com. The bikes were donated by Williams' children, Zak, Zelda and Cody, and proceeds will go toward the Challenged Athletes Foundation and Reeve Foundation.

"Though bright, skin-tight spandex still remains one of the more embarrassing outfits to regularly witness your Dad wearing growing up, the sport of biking and the people Dad helped through his love of it, will always hold a special place in the hearts of our family," the family said in an statement. "Causes like the Reeve Foundation, championed by his longtime friends Chris and Dana Reeve, and the Challenged Athletes Foundation, in whose triathlons he often biked, were both deeply important to him and we're honored to be able to continue to support them both in Dad's name.

"We hope these bikes will bring their new owners as much joy as riding them, and helping these causes, always brought him."

Williams was no casual cycling fan; he attended the Tour de France and biked in many events of his own. As such, the lot includes rare team issues and custom-made bikes. And, for comedy of course, there's a unicycle.

The auction runs through Oct. 25 and comes with a very sweet suggestion courtesy of the Williams children:

"Though not required, may we suggest wearing the loudest, most vibrant and brightly-patterned, skintight biking gear possible when riding them?" they said in a statement. "Keep the tradition alive."
