Test driving the folding bike – how it rides, how it folds, and how it fits in the back of an airplane. All are remarkable. This is a Dahon Boardwalk. It’s a single speed bike with coaster brake and a front hand-brake. It has a 42×14 gearing and 20″ wheels, which works well, even with 24 gusting 28 knots headwind and up the mild hill of our court. It folds and unfolds in only a few seconds. 1 fits easily in the back of the mini, multiple in the back of the Archer. And, contrary to what it looked like by the numbers, it fits through the Archer baggage door. Altogether, this is exactly what I was looking for.
