Customers always ask me about riding off road with a small wheel folder. I tell them don't do it, it's dangerous. Small wheel rotate around obstacles ( like rocks ). Hence it is likely to get thrown head first off the bike.

My job is to test these bikes everywhere, so I learned how to ride off-road on treacherous single track with our folders. There is one major change from large wheel bikes. Your butt has to be extremely light on the saddle. Once you make contact with an obstacle or a hole, you must pull your butt behind the saddle. This moved the center of gravity further down and back. Essentially making it impossible to be thrown off the bike. This way you can enjoy the mountain biking without the injury risk associated with flying off.
