[Adding additional context to my previous post.]
For the type of riding you mentioned, you can't beat the value found in the Jamis Coda:
coda
- Steel frame (solid, and softens the ride)
- Relaxed geometry (not too bent over, but not too upright)
- One of the most respected bike manufacturers in the world
- Components are fine for what you need
- Strong wheels
- Although it's not a critical piece, the colors on the 2017 models are good.
- You can't beat the price ($369 for 2017 base model)
In comparison to the base-model Jamis Coda, the Coda Sport offers an upgrade in components, but the ride will be more aggressive due to the handlebar stem angle. For me, that would be a deal-breaker because of reduced comfort (and added cost).
As others have said, if you go with Specialized or Trek, you'll pay extra for the name.
Giant is a strong option as well (Escape or Roam series). All things being equal, Giant and Jamis tend to give you the most for your money.
If I didn't own a Specialized Sirrus Sport (found it on Craigslist), I'd buy the Jamis Coda in a heartbeat.
Good luck!
