Tsunehiro Cycles

Hi, I’m Rob Tsunehiro, founder of Tsunehiro Cycles LLC.  My front door is in SE Portland, and a wonderland of forests, canyons, fields, and mountains lay beyond. Long days in the saddle are my favorite.  They’re brutal and exhilarating, sometimes remote and adventurous.  I can push myself further when I have total trust in my equipment: a bike that fits correctly, steers intuitively, and functions reliably.  Through each detail of its design and craftsmanship, building the bike you can depend on is my priority.

As a teenager I knew I wanted to design bicycles.  I went to school for Mechanical Engineering and focused on materials and product design.  My first job out of college was at Boeing in Seattle, designing fuselage structure for the 777.  Sculpture welding classes in Seattle and a framebuilding course at UBI introduced me to the craft.  When my fiancée was accepted to grad school in Portland, I decided to take the leap.  I entered the welding program at Portland Community College and built frames for friends.  In 2008 Tsunehiro Cycles opened its doors, building TIG welded steel frames for road biking, touring, commuting and cyclocross.  Getting people on bikes that perfectly fit their needs is my passion.
