The Joe by Tern is a full size folding bike with 26" wheels. That means it has the same feel as the average mountain bike - namely stability. The Joe folding bike is your best choice if you need to ride on rough pavement or dirt because larger wheels just swallow holes better.
The Joe is easily to fold to fold up and can be stuck right in the trunk of your car. No more fiddling with setting up a bike carrier on your car. It can also easily fit on trains and buses.
