Bought my son the 18\" hot wheels bicycle for his 6 yo birthday 10/15/2014.   They said they would assemble it for free, done by the next day. When I got it home my son started riding it, and the wheel fell of and my son fell face first into the street.  Upon inspection, I found all of the bolts to be finger tight, and the front forks were backwards.   It was assembled so poorly it felt like one of the teenage workers was trying to pull a prank on us.  The problem is my son is now scared of the bike after his crash scabbed his face.  If you purchase a bicycle, just make sure you inspect it very well.
