I have assembled this wheel with the enclosed tool. This went quite well so far. Unfortunately, it is the screw cover under the saddle not fit if you want to make the saddle all the way down. Despite the deepest saddle position our son (almost 4 years / 99cm height) is just so with your feet on the ground. But now the hammer: The plastic rims have such an impact, that you can not adjust the brake; either the brake drags brutal or she does not brake stop. The wheel bearings I had both follow because they were loose. However, they caused significant then running noise (Board does not guarantee quality). The "camp" for the handlebars are simple plastic sleeves of their durability, I'm not convinced. The Gau I experienced with the tires. I have the tire is normally inflated (2.0 - 2.8 bar). The bike was a short time in the sun and already bursting both tires. We are glad that's not happening while driving. That something like wearing a GS mark, is beyond me. I'll give back the wheel quickly!
