Proteus Bicycles has been a College Park institution for 40 years.  Proteus moved to its former location — a former auto repair shop (we think) — on Route 1 at Erie Street in College Park in the 1970s. In the early days, the shop built custom bikes and bicycle frames, including special orders for racers.

In December 2018, the shop moved to a larger and nice location on Rhode Island Ave., just a half-mile down the street. We’re in the same shopping center as the new Mom’s Organic Market, and the new location gives us room to grow for the next 40 years!

Proteus History Quotes and Fun Facts


1972: Across the street from the University of Maryland, 3 young bike enthusiasts decided to make their own bikes and a booming business was begun. Proteus took a very hands-on, proletariat approach… you could buy a bike frame, or a bike frame kit, or have your kit’s tubes mitered by Proteus, or have your bike painted after you made it at home!

Proteus also was a prime supplier for building bits and tubing. They published a frame building manual (even had a second revised edition, both sadly long out of print) which made the magical art of frame construction more accessible to the average craftsman.

Frames were made by various employees who changed regularly, yet, on occasion, highly trained master builders also came & went at Proteus. Perhaps most notable was Koichi Yamaguchi, who went on to have his own workshop in Colorado and build quite a reputation.

From The Washington Post by Hank Burchard from 1977 (as reprinted in the Milwaukee Sentinel).

“Proteus front office is a head shop for bike freaks…”
