Hurtling along the corridor of the Colossus at breakneck speed, this brainless biker will keep kickin' 'til you bite the dust. - Official description from the manual.

The Ryder is an enemy in Battletoads & Double Dragon. They are enemies on hoverbikes who appear in the tunnel in Level 2-3, where players must fend them off while riding their Speeder Bikes. They can be pretty tricky, since they can knock the player off their bike, causing an instant death if he's not careful.
