I've done a few of these with this company. I'm even in a couple of their pictures on the website

Bike Tours & Vacations - Velo View Bike Tours

There are two divisions of this company. One based in TN and another in TX. I really like the TN based folks, Shannon and Celeste.

My spouse doesn't like to ride as much either and she enjoyed the trips she did with me where she didn't do all the rides. Their trips are based around couples and are at locations where non riders would enjoy the trip as much as the riders.
