this is a disappointing one. it's adorable bike and my son loves it, but i purchased it for christmas and as i was up late christmas eve i had to re-drill pilot holes that weren't the proper size and depth for the screws included for assembly, not to mention the fact that they weren't properly lined up either. the hole thing should have taken about 10 minutes and ended up taking around 2 hours. i had to hammer this thing together like a caveman, and was left with a lopsided crooked scooter bike. i wish it had been manufactured with a little more care. sadly the factory machine assembly line world we live in doesn't offer much quality.
