From the little I've looked I kinda like the Trek FX 2. But it feels like that shyt is hard to find and the places that have it are like $700-800.Personally I like trek since they have dedicated stores and I didn't see that with other brands. Similar to apple, when your stuff acting up just head to store and you good. Obviously most lbs will be to do the same thing though.
I was hoping to find something used closer to $500.
Locally on Craigslist and OfferUp there are bikes for sale, but most of them are either too small for me (I'm 6'4) or they're old bikes from like the 1980s or 1990s.
