The only way to make them submissive is to convince them that you are worthy of being submissive to. If you avoid eye contact, back down, avoid confrontation, etc., you become the submissive.

Stop your bike, stand your ground, be a threat, make the dog think you are the head of his pack or, at least, not something that is worth messing with. Dogs are cowards and will act as such when you remove the chase urge. About 50% of all dog encounters can be solved by yelling a very loud "NO!" at them while riding. About 99% of all dog encounters will end when you stop and yell "NO!" at them. For the 1% that don't stop, most of them are going to be taken care of by a swift smack in the nose with a bike wheel. They don't like getting that sensitive bit hit.
