... So I tried to get an idea of how the folding guitar would pack on the bike.
As I noted before, the bag that comes with it is somewhat bulky, but maybe viable. The bag and guitar total about 8 1/2 pounds (3.9 kg).
However, the guitar will fit in a much smaller bag. This is a duffle I use as a carry on. If it were a little larger, the neck could sit next to the body rather than on top, so the package would not be as tall. A plain fabric duffel would be about a kilo lighter than the manufacturer's bag.
