Well actually it isn't exactly presto change-o.

Wrestling them into suitcases takes about another two hours (maybe just one if you really know what you are doing).
"The bicycle is a parody of a wheeled vehicle -- a donkey cart without the cart, where you do the work of the donkey." - P.J. O'Rourke
