I think that one won't work for me. When I ride the rails to trails I want a bike that is a little lighter with skinny tires so that I can go faster and go to the next town and back.
When I'm riding in my neighborhood, I ride all the way around the lake. The road bike is too lightweight because I find myself mostly coasting. Also, across the dam and spillway there is a short area of grass. The skinny tires of the road bike are dangerous.
I once tried the road bike on an old country road where dirt and sand had washed across. Need wider tires for that too!
The mixte would come closest if I had to choose only one. I have mixte fever!
