Basically, I dont really have any useful melee weapons nearby, but I would see them through the window in front of me, so I would have a couple of minutes to prepare. The best stuff I could use as weapons would be my guitar and a frying pan. I would go with the frying pan, since the guitar would just get stuck into the zombies. I would also grab a thick coat to protect me from zombie bites, maybe something to cover my head too.
Then I would make a run for my bike and just use it to get away. The zombies are slow, so I could get away from them. Besides, most major roads would probably be blocked by the undead, so using the bike offroad would seem like a good idea. I actually live near a bunker. Its pretty firm + it has food and supplies for a really, really long time, since the supplies are meant to aid people in different sort of disasters around the world and since they cant really send any crap moving, anyone inside would probably get the whole motherload.
