About an hour ago, I sent my youngest son, (43 years old), home, with a Marin hybrid to road test. He's looking for a commuter bike, and doesn't know the first thing about them. I told him if that doesn't do it for him, come get a drop-bar road bike to try. When he decides what he wants, we'll go together to the bike shop and get him a new one.
My 23 year old granddaughter borrowed the same bike a couple of months ago, and then we went to the bike shop and bought her a nice GT hybrid.
I have a few more bikes stashed for the younger grand kids. A great way to get riding partners!
