A thought: walk by his yard while pushing your bike. Make sure you are wearing your helmet and sunglasses. Call out to him, give treats. After the dog is calm, get up on the bike. Talk to him. Get down. Push. Evaluate situation. Get on bike and ride slowly for a few feet. Get off. Push... So introduce the idea of 'bike' to doggie. Let him see it is you on the bike. Then when you go by quickly in the future, you should be safe calling out to the dog and slowing to a stop so his doggie-brain figures it out. (If it seems like it won't work, don't actually get on the bike the first time. But be prepared to take it slow and wait).
And if the owner walks his dog, could you go along with and walk beside or in front? (Never behind, that will make the dog more dominant). Only if the owner has good control on walks though, and knows how to handle the pooch. (Owner shouldn't walk behind, you may lose before you start if the dog is in charge of the owner, stay away then).
