this 9$ Cardboard Bike Can Support Riders up to 485lbs.
okay... this is cool
but really... it is not a 9 dollar bicycle
it took years of Research and Development
if it has any cables... well... cables alone would cost you close to 9 bucks
then brakes and brake levers... your shipping could cost you 9 bucks
so... not so sure about the 9 dollar cardboard bike
especially if it is raining
