The bike has started immediately and runs fine. The tank was leaking but move easily to a bit that's done. The paneling was easily cracked, but there are superglue. I bought this bike for my son, but I've also tried it. The rear tire had a defect he was exchanged without any problems. The communication was very friendly. The quality of the bike is great, it's just fun (even the mums). The shipping was very quick and was super packed.
