Most people knew Mert Lawwill from On Any Sunday. The film that defined an era featured the calm, almost effortless rider alongside Steve McQueen and Malcolm Smith. But his impact didn’t stop with motorcycles. It carried into mountain biking, right at the beginning of the sport. The 1969 AMA Grand National Champion, suspension innovator and early mountain bike builder died May 6 at 85 in Idaho, surrounded by family.
Building bikes before the industry existed
Before mountain bikes were a category, they were a project. Riders in Marin were piecing together clunkers, experimenting with gears, trying to make something that could climb and descend. Frames were being built, and Joe Breezer produced ten bikes in 1977, but was ten bikes really production? Lawwill saw the gap. From 1977-1979, he produced the PRO CRUISER: widely considered one of the first complete production mountain bikes.
That might sound obvious now. It wasn’t then. Early mountain bikes were mostly parts-bin builds. The idea of a purpose-built, ready-to-ride machine was new. Lawwill helped make that shift real.
A racer’s approach to design
Lawwill’s work on motorcycle chassis design set a standard through the 1970s and 1980s, built around feel as much as theory. That thinking translated to bicycles. He went on to design a four-bar suspension system later used by brands like Yeti and Schwinn. He also came up with the Lawwill Leader, an early leading-link fork that showed just how far ahead he was thinking. By the ’90s, racers were winning on ideas that traced back to that work, reinforcing just how much influence he had on modern mountain bikes.
Not everything stuck. But enough of it did.
The work that mattered most
For all the racing and innovation, the project that stayed closest to Lawwill was personal.
After a friend lost an arm in a crash, he developed “Mert’s Hands,” a prosthetic system that allowed riders to stay connected to the bike while still being able to release in a fall.
A legacy that’s easy to miss
Lawwill’s influence doesn’t always stand out. It’s in the early days of mountain bikes becoming something you could actually buy. In suspension ideas that evolved into what riders use now. Two industries recoginized his contributions; he’s in both the AMA Motorcycle Hall of Fame and the Mountain Bike Hall of Fame.
He is survived by his children, grandchildren and a wide…
