Merida is an international bike brand with its headquarters in Taiwan, the R&D department is based near Stuttgart in Germany. To be based in Germany has historical reasons for MERIDA but the precise location was chosen specifically because the region around Stuttgart is one of the hot spots of the automotive and machine building industry which Germany is famous for and attracts a hugely skilled design and engineer labor force.

The Merida team are more than just highly trained and experienced bicycle creators – they simply love everything ‘bike’. Most of their R&D staff are daily bike commuters while others are serious mountain bikers, who regularly compete in Marathon, Enduro and Downhill competitions, or licensed road racers and even ambitious Ironman triathletes.
