I wanted to put some bikes on the Precept and considered buying an expensive rack to mount on the trailer hitch and then buying some full size bikes - but my wife suggested getting two folding bikes and when doing some research came across a really nice folding electric bike.
Folds into a small size and then fits into a carrying bag and can be carried in a storage compartment perfectly. No bikes hanging on the back of the RV- less worry of theft and these electric ones will run for around 25 miles.
Not cheap but I thought worth the cost all factors considered....

This website provides some information and There are several video reviews on youtube. Also there are other companies selling folding electric bikes. Should help eliminate the need for a tow vehicle in some places.
