Specialized’s tig-welded Stumpjumper, designed by Tim Neenan, was the first mass-produced mountain bike.

 

Before the Stumpjumper, mountain bikes were being hand built, or around-town bikes were being individually modified to make them trail ready. The process was expensive and there was a long wait time for a custom bike.

 

The Stumpjumper was mass-produced in Japan based on the design for a custom-made bike originally marketed by Tom Ritchey, Gary Fisher and Charles Kelly.

 

It sold for $750, and had French touring parts (brakes and cranks), Japanese parts (hubs, shifters/derailleurs), motorcycle-sourced brake levers, and a BMX stem and pedals.
