The B&W Foldon Case looks just like any rolling luggage with a telescoping handle; in this case the difference is it can accommodate a folded Brompton. An aluminum skeleton protects the bike from accidental impact and knocks and dings it might otherwise sustain without a protective box. This case comes with TSA locking clips and can even be used as a suitcase. The internal dimensions are 24" x 26.4" x 9.4", the external dimensions are 25.2" x 27.6" x 13", and it weighs 15.9 lbs.
