Concept USA is a high-end line of accessories made by Univega, the bike line created by industry legend Ben Lawee. Lawee started as a sales representative of the Joannou bicycle wholesale company, but soon was the owner of the Jones Bike Shop in Long Beach, CA (a long way from his birth city of Baghdad, Iraq). He grew that one shop into a chain. In 1959 he sold the chain and began importing Bianchi bicycles while also becoming the US distributor of Raleigh and Motobecane.

In the early 1970s he created his first private-label bike line, Italian-made Italvega. When exchange rates and product availability prompted a switch to Asian-made bikes, he created the Univega line, the Alpina MTB line and others, like Concept USA.
