I've just bought this bike off eBay and it's got a flat tyre, but I can't undo this bolt.
It's a 5 sided bolt, and it doesn't look like a torx bolt (I think) and I can't find anything on Google. Allen key doesn't fit.

This is a security feature meant to make it harder to steal the wheel. A responsible seller would’ve included the driver to remove it in the sale. I’m not gonna say it’s stolen, but that is kind of a red flag.
It goes by a lot of names: pentagonal drive, penta plus, 5 sided security, etc. You can get a set of bits for $10-20 and one of them will likely fit, or you can hulk them off with a set of vice grips or channel locks, which will destroy them, and replace them with normal nuts.
