Folding Bikes

DW and I are thinking about getting folding bikes to put in our 5'er. Never been comfortable with bike rack on back of rig. Would appreciate some recommendations from those of you who have them. FWIW, we don't do a lot of biking. Maybe just to town where we lock them up and then walk along the shops. In other words, we don't need something that is designed to go thousands of miles. :)Thanks
