Are you wanting to ride on trails or just on paved roads/paths? What are you looking to spend? If road riding is all you're looking to do the bike in your pic should suffice if you dont mind single-speeds. I prefer them personally. I'd get a water bottle/cage and maybe a saddle bag with a multi-tool in it along with an extra tube too. Also one of these to keep in it
