I always find something interesting to see at Urbane Cyclist.
They are now carrying the Yuba Mundo, in addition to the Xtracycle.
And here is a Tern branded semi rigid, oversize suitcase. The label said that it is good for their 20″, 24″ and 26″ wheeled bikes. It is beside a Bike Friday travel case, a Samsonite Flite case which is about the maximum allowable size for checked luggage (without oversize charges). This gives you an idea of how ginormous the Tern case is.
