Welcome! A bike to enjoy riding on does not have to be an expensive bike, and it can certainly be upright. But it does have to be in good working order, and it shouldn't be too heavy, especially if you're a smallish rider or ride up hills.
Gears on a bike are pretty essential for most people to be comfortable riding on anything but the flats. The main difference between cheap bikes and slightly more expensive bikes I think is mainly weight, and maybe how serviceable the components are. Used bikes are a great way to get a decent bike for not too much money. I have four bikes, and 3 of them were bought used
But if you make sure the chain is lubed, there's plenty of air in the tires and the brakes aren't rubbing, almost any bike will be fun!

Winter riding is much less about badassery and much more about bundle-uppery. - malkin
