(TC) Robin Williams’ Bike Collection Being Auctioned for Charity — and His Children Suggest

Some of Robin Williams‘most prized possessions are being shared with the public for a cause that was close to the late comedian’s heart.

Williams’ collection of 87 bikes is currently up for auction through Paddle 8, with proceeds going to both the Challenged Athletes Foundation and the Christopher and Dana Reeve Foundation.

All 87 of the bicycles — which range from racing to mountain and come from numerous artists — were donated by Williams’ children, Zelda, Zach and Cody.

“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 children said in a 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.”

The Williams children added, “We hope these bikes will bring their new owners as much joy as riding them, and helping these causes, always brought him. And though not required, may we suggest wearing the loudest, most vibrant and brightly patterned, skintight biking gear possible when riding them?”

Williams was an 11-time participant in the Challenged Athletes Foundation’s San Diego Triathlon Challenge before his 2014 death, competing alongside participants like double amputee Rudy Garcia-Tolson, a two-time Paralympic gold medalist, according to a release from the Christopher and Dana Reeve Foundation.

The actor was also a longtime supporter of the Reeve Foundation — he met namesake Christopher when the two were roommates at the Juilliard School in 1973.

“Robin provided unending support without fanfare or question and became a powerful voice for the 5.6 million Americans living with paralysis,” said the foundation’s CEO and president Peter Wilderotter in a statement. “Thanks to his efforts and the generous contributions of his family, cures for spinal cord injury are now within reach. Being part of this auction with Challenged Athletes Foundation is a beautiful way to honor his legacy of giving.”

The bike auction runs through Oct. 25 on Paddle8.com.
