Robin Williams was more than just an amazing comedian. He was also an avid cyclist and an advocate for people with disabilities.
Now, more than two years after his death, 87 bikes from his collection are up for auction and the proceeds will go to two charities he supported, according to CNN.
Williams' children -- Zak, Zelda and Cody -- made the donation.
The two charities are the Challenged Athletes Foundation, which gives grants to athletes with disabilities, and the Christopher and Dana Reeve Foundation, which funds research and support for those with spinal cord injuries.
"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 Williams family said in a statement to CNN.
The family added that they encourage the buyers to continue the tradition of wearing "vibrant and brightly-patterned" biking gear when riding the bikes.
Williams' collection is up for sale on Paddle8.com and the auction will run until Oct. 25 at 1 p.m. ET.
The collection includes everything from a Z Turbo electric scooter to a Schwinn unicycle.
In total, the auction could bring in upward of $200,000 for the nonprofits.
