Well, yes bike is dangerous on villager, if villager is camping at the edge, you are in a 50-50 scenario where you stay on the bike and hope he tries to pocket, or you get off the bike and hope he tries to use an offensive maneuver like fair or loyd. Also if you hit him with the bike while loyd is still coming out, you can put villager in an awkward position as you will be right next to villager, and all of villagers short range options are pretty dangerous on shield except for maybe f-tilt? Don't quote me on that. If he tries to run or jump away he will more than likely eating a forward air before he can get a slingshot out. Really villager's short range options kinda suck. Plus obviously there is waft of course. Run up shield is probably wario's safest option, but usually has little reward. Obviously a good villager will start punishing this right away though, so be ready to spot dodge. But most importantly, I have to disagree with villager's recovery being safe. It has no hit box, which means if wario grabs ledge at the right time, villager is limited to grabbing ledge from below or the side, in which case he will eat a down air and the process will repeat, or he will go back on stage which will get him into a bike setup or maybe even a forward smash if wario is fast enough. Obviously villager will throw out up airs and slingshots to get you out of his way but you just need to use ledge invincibility to its full potential. D-air off stage can also get villager stage spiked if he doesn't tech well which puts him in an even worse position. But on stage, wario can't do anything to get past the tree or loyd considering his coand grab becomes essentially useless and all of his approaching aerials are unsafe on shield, so wario will eat a grab combo or maybe even a bowling ball if he uses dair, and not to mention the kill throw. Plus even with the bike, wario is going to die off stage because if he gets hit off of it, he loses it until he stands on stage again. Something to keep in mind for this matchup though, is that the tree will add hit stun onto the waft, so you can catch villager off guard, providing you can get in safely. In my opinion this is 55-45 villager, at least. Villager conditions you to shield and uses the new buffs to rack up and then run until you you are at high enough percentage to get kill thrown. Wario has to be extremely careful using the bike, as well as jumping, but jumping goes said for all characters.
