About us

Inspired by a passion for bikes and mechanics. Driven by the quest for quality and perfection. That’s how, in 2010, we started distributing the Taiwanese CEMA products. Although on a small scale on the Belgian market, a top-class product catches the eye and is in demand. Also abroad the interest was quickly aroused, so today we are serving the entire European market.
