Charlie is best known as the man who made the first mountain bikes out of oversized aluminum tubing. But his MTB innovations were numerous as outlined in the link posted by crank_addict.

Charlie is an artist and an inventor, not a business man: He could really use your help right now as he faces a long regimen of rehabilitation once he comes home from the hospital. Please consider donating via the link in the first post.

Thanks,
Brent
