Diamondback Cycles Established 1978

Diamondback was founded in 1978 by a small United States west coast distributor Western States Industries (WSI) who originally sold road bikes under the Centurion brand and later introduced BMX under the Diamondback brand.

From 2009 onwards, we see Diamondback bikes represented by trials legend Martyn Ashton and his Ashton/Diamondback team who propelled dirt and slopestyle star Sam Pilgrim onto the world scene. This multi talented mix of riders also put Diamondback in front of millions of consumers at the famous Animal/Relentless Bike Tour.
