Query: Great Bike, Very Sturdy

We purchased this bike for my son's 5th birthday. It arrived only about 4 days after I ordered it. It was not very complicated to put together, but the instructions included other bikes as well, so that was a little confusing. The only thing that I was disappointed was the blue plastic that covers the chain- the sticker on it was slightly crooked and coming off a bit. But, all in all, it's a great bike and my son absolutely loves it!!
