carrying a person on a rear rack (?)
so, i was just in vietnam, and aside from the delicious food, extreme heat, and a whiny family, i had an amazing time. my uncle let me borrow his bike and i rode it around for hours......with my dad sitting on the rear rack, right behind me!
my question is--where can i find a bike like this? can a bike be converted into a person-carrying (utility) bike? the crazy thing is--these bikes in vietnam don't look too beastly, but can carry an insane amount of weight.
here are some photos for reference:
and this is the one i rode with my dad:
i was so in love i even looked into buying one there (they were around $60) and having it shipped, but shipping was to the US was some crazy amount. i've heard that actually welding a rack to your frame would work, but i could swear the bikes in vietnam just had normal-looking racks attached.
any advice/suggestions/things i should know?
thanks in advance!
