This is the perfect suitcase to protect your Dahon folding bikes from the rigors of airline travel. The Airporter is a hard-sided suitcase with plenty of protective internal padding. It is large enough to fit any of your 16" or 20" bikes when folded normally. It will also accept Dahon's 26" bikes with the wheels removed. The Airporter features rugged straps and zippers and bomb-proof in-line skate wheels.  Outer dimensions: 33"x27"x13". Please check with your airline for their possible oversize surcharge policies. Fits Dahon folding bikes only.
