I would strongly consider a mountain bike unfortunately not a 150$ one. You don’t need to go off road to enjoy the advantages of a mountain bike. I have two road bikes and a mountain bike. The mountain bike is the most useful and even when I want to just ride around town I don’t worry about curbs or potholes or anything like that. If you don’t want the knobby tires of a mountain bike you can always buy the wider commuter tires And slap them on. Like someone else said buy yourself a decent one, meaning a non big box store bike. You’ll enjoy it and tend to ride it much more than a shoddy bike from a place like wal mart.
