We purchased this bike for my five year old son for his birthday. We were unable to find a Spiderman bike at any of our local stores, so we decided to make an online purchase. The price was very low, and we received free shipping which was great! The bike arrived quickly, even though we had chosen super-shaver shipping. There were some issues with the bike. Once the bike was put together and our son tried to ride it, we realized the front and back wheel were badly warped. So much so, that the rear wheel rubbed against the brake very badly to the point that my son couldn't pedal the bike. We were pretty disappointed to say the least. However we called the warranty number in the booklet that came with the bike. I was told how to submit my request for new wheels by e-mail, and did so. We received the two new wheels within days of my e-mail request and were able to put them on his bike. The new wheels are great, and we are having no more problems with them. I'm not sure if maybe the wheels were damaged during shipping (as the box the bike arrived in looked slightly beat up), or if this was a manufacturer's problem. Anyway, the problem was resolved and the new wheels were free of charge.
One other problem I would mention with this bike, but that isn't a real big deal, was that the front faceplate that fits onto the handle bars fell off. The little plastic zip ties that hold it on, broke immediately. They were very brittle. This isn't a huge problem, as the bike looks fine without the plate. But we will need to purchase some new zip ties to put the plate back on.
I normally would have given this bike a 3 in the review, but decided to give it a 4 because our warranty needs were met immediately, and to our satisfaction.
