Here are some pictures of the paths that I tend to ride my bike on:
(The first picture is the best one. Unfortunately, it's too big to display in the post).
As you can see, the paths are covered in gravel but they are flat so I don't need to worry about hills or anything like that. Also, puddles form in the winter.
What type of bike would be best suited for this? Feel free to post links.
P.S: I would really like to get something like this, but I don't think it would handle the path that well given that it's a road bike. Can someone confirm this?
