This bike arrived in a box & was a bit tricky to put together, I ended up taking it (and another bike from Great Offer Stock.com) to a local bike shop for them to put together for me. The instructions on this bike were very very hard to read & some of the brake lines were tricky to put together. The instructions read: "If this is a model that needs an Allen wrench, use it to....." I have an Allen wrench but don't know too much about putting bike brake lines together. In the end, after paying the guys at the local bike shop to put it together, I still feel like I got a great bike for my kid at a fairly good price.
