Motorcycling and mountain biking lost one of their most influential architects this week. Mert Lawwill, a man whose name is synonymous with speed, suspension innovation, and the golden era of American racing, passed away on May 6, 2026, at his home in Idaho. He was 85 years old and surrounded by family and friends. Now I know why all the flags here in Idaho were at half mast yesterday…
To many, Mert was the smooth-riding star of Bruce Brown’s 1971 classic On Any Sunday. To those in the mountain bike world, he was the visionary who helped pull our sport out of the “klunker” era and into the world of high-performance suspension.

Born and raised in Boise, Idaho, Mert was the son of a house painter and a schoolteacher. He grew up as one of seven children, developing an early reputation for using his creative ingenuity to dodge chores in favor of mechanics and motion. That drive eventually led him to the pinnacle of motorcycle racing.
A Mountain Bike Pioneer
When Mert transitioned his engineering mindset to the bicycle industry, the results were nothing short of revolutionary. Long before mountain biking became mainstream, Mert produced the PRO CRUISER in 1977, one of the world’s first production mountain bikes.
The Four-Bar Linkage: Lawwill designed and patented a four-bar suspension system that became a cornerstone for brands like Yeti Cycles and Schwinn.
The Lawwill Leader: He developed the groundbreaking Lawwill Leader, a leading-link suspension fork that pushed the boundaries of what front-end bicycle tech could do.

Racing Success: Throughout the 1990s, elite racers on Lawwill-designed platforms dominated tracks, proving his mechanical intuition was decades ahead of the curve.
“Mert’s Hands”
While the championships and patents defined his professional career, Mert often felt his most meaningful contribution was “Mert’s Hands”.
Motivated by his close friend and fellow racer Chris Draayer, who lost an arm in an accident, Mert engineered a prosthetic device. This innovation allowed riders with limb loss to maintain a secure connection to their handlebars while safely releasing during a fall. It was a project born of pure empathy, opening the door for countless adaptive athletes to return to the sports they loved.
A Life Lived on His Own Terms
Mert is survived by his son, Joe Lawwill—himself a decorated mountain bike racer—his daughter Marcella, three stepsons, and three grandchildren. In a moving tribute, Joe Lawwill reflected on the surreal experience of growing up with a father who was a global icon:
“As I grew older and pursued my own career in mountain bike racing, he remained my most steadfast supporter, always encouraging and standing behind me… I have always felt a deep sense of gratitude and honor to call someone so impactful my father.”

Mert Lawwill was a man of unfailing good nature and a sharp sense of humor. He didn’t just follow the path laid out for him; he engineered a better one—whether he was sliding a Harley sideways at 100mph or sketching out the future of downhill mountain biking.
A celebration of life will be held at a later date. For now, we tip our helmets to a true legend who changed the way we all move through the world.
