Beginner looking for some help.
So I started cycling last year and did around 600 miles between summer and late fall. And since it’s warmed up this year I’ve done almost that much already. I have a Walmart bike and that was good enough for seeing if cycling was something I’d enjoy and it turns out I thoroughly do but it’s showing some wear and I don’t think it’s worth replacing parts on. So I’m looking to upgrade to something that will last me longer and will perform better. Cycling for me is just for exercise, I won’t be doing races or events, just riding on 95% paved trails an hour or two at a time 3-4 times a week. The research I’ve done has made me think a hybrid is what I’m looking for. I’d like one with disc brakes and a decent amount of gears. I don’t really understand the difference between freewheel and cassette but I hear cassette is better but I don’t know how to tell if any given by has cassette or freewheel. I tried two local bike shops and their prices are higher than what I’m willing to pay right now. I’d like a giant or trek. So I come to you Reddit to tell me what specific models to look for on facebook marketplace as that’s where I’ll be looking. I’m not looking to spend more than 400$. Thanks for any help.
