found this online....bike tours with bikes included, or bike rental. not a recommendation.....and there must be others out there.

they have a 14-day tour from saigon to bangkok. a bit expensive at $2750, or can rent bikes in bangkok or chiang mai at about $15/day.


and googles shows us a bunch of bike rental shops in saigon....imagine schlepping two bikes to o'hare in the snow and slush would be a miserable experience.
