Charlie Cunningham, Mountain Bike Innovator, Dies at 77
Charlie Cunningham, Mountain Bike Innovator, Dies at 77
In the late 1970s, he built what is considered the first off-road bicycle with a frame that was aluminum rather than steel, one of his many inventions.

Charlie Cunningham, a pioneer of modern mountain biking who viewed bicycles as a means of combining technology and nature in a friendly symbiosis that the automobile could never match, died on June 2 in San Anselmo, Calif., north of San Francisco. He was 77. … His death, at a care facility, was from complications of a 2015 biking accident in which he sustained severe head trauma, said his wife, Jacqueline Phelan, a writer and former national off-road biking champion who is his only immediate survivor.
While cyclists have ridden on dirt roads and trails since the 1800s, the era of modern mountain biking began in the late 1960s and early ’70s. In Marin County, Calif., enthusiasts bombed down unpaved fire roads on what were known as klunkers — single-speed cruisers with balloon tires. … As the sport became more sophisticated, bikes began to be built specifically for off-road terrain. The term “mountain bike” was coined, and downhill races were organized. Mr. Cunningham, who had a background in engineering, joined other germinal figures in the sport — including Gary Fisher, Joe Breeze, Tom Ritchey and Charlie Kelly — in creating innovative designs and developing this emerging branch of cycling.
Starting in 1978, he built the CCproto, which is considered the first mountain bike with an aluminum (rather than steel) frame, made of oversized tubes that were light and strong. His other innovations in off-road biking included knobby tires built for traction and control; a unique braking system that allowed for controlled stopping; and a patented lubrication system that flushed out old grease, water and dirt from a bike’s sealed bearings, injecting fresh grease.
“To put it bluntly, if it had to do with mountain bikes and it was either invented or became popular before 2000, there is a good chance that Charlie Cunningham had either filed the patent, sketched a drawing, made a prototype or discarded the concept as fruitless,” Richard Cunningham, a bike designer and cycling journalist who is not related to Charlie Cunningham, wrote in 2018 on Pinkbike, a biking website.
