Agreed, rifles are the best bet, and it's easy to carry large quantities of ammunition such that you should be generally safe. That, in addition to a bike, will allow you to be mobile and powerful, even when others lose their transportation due to loss of fuel/exhaustion from running.I carry 15 mags with 30 rounds each on me. That's 450 bullets, and I've still got plenty of strength for more, especially when I start dropping kit that's unnecessary in a zombie outbreak. That's a lot of fucking bullets. Like I said, melee is a backup, but if your fighting a horde big enough that 450 bullets don't cut it, then a) stupid you for going alone, b) stupid you for fighting a horde that big rather than running.
My two cents

If a zombie invasion occurred, I'd carry a rifle(Semi-auto, aim for the heads, don't want to waste any ammo with an automatic.), around 200+ bullets, 2 gallons of water, a backup weapon, and some snack food while riding around on a bike. The bike will grant you speed so that you can flee far away if you see a very large group of zeds, or if your city is entirely over run with them, while the rifle can be used to clear a store from a bit away for your search for supplies to stock up on.
As a backup weapon though, I'd likely go for a crowbar or some kind of axe, as those would be useful as tools as well as weapons in a tight situation and could be used to break locks where I don't have the time to pick them.
Not to burst your vehicular bubble, but not everyone will have super-filled their cars with gas. Likely you will have all the streets filled with empty cars. Also, their is no gaurantee that an infected person didn't get ahead of you before dying and starting up a new horde at your secluded gas station.I was starting to think no one else had read the Zombie Survival Guide. Or are you just a straight thinker?
Though personally I don't go with all this talk of cars are useless due to fuel. Well, depending on the car at least. I know that on average America uses 1.7 the amount of fuel per car other countries use. But anyway, find a good car, fill it up and carry an extra tanks worth in the boot. A bicycle in the back seat, unless you have friends, though they could do the same and have a convoy. You will have at least a days worth of straight driving, and it's not as if fuel is hard to find is it? In the time it takes a horde to catch up that 10 miles to that remote gas station you carefully cleaned out earlier you could refill a hundred times, clean your weapons, reinforce your ride again, and do whatever. All whilst grabbing a snack and last weeks newspaper.
A car allows to carry all the ammo you can find rather than leave it behind and risk running low latter on. And unlike in the movies, a car doing 60 is not an easy thing to simply grab onto, nor do doors and windows fall off like tissue paper. If you can find a vehicle with genuine off-roading abilities not even the densest horde will stop you crushing hundreds in each charge. Otherwise choose a good blend of fuel economy to power ratio, and have a friend shoot while you pull up every 200 meters. If it comes to it, you can always ditch the thing and take your bike. Or, find another of the millions of cars infesting our planet. I seriously doubt the zombies are going to have the foresight to take their keys with them when they leave home. People put them in obvious places. Stay mobile, stay versatile, stay alive.
