Review: Great First Bike - It was a Christmas gift, and the child loved it. It was fairly easy to assemble. We had a blow out of the inner tube overnight, but the seller sent a new one right away.
Review: A Happy Birthday - I bought this bike for my grandson's 5th birthday. His favorite color is yellow so he loved it. It was easy for his Dad to put together. I live 3 hours away from them so I had it delivered at their house. That worked out just fine. Thank you!
