I bought 2 of these scooters. The assembly is actually simple. However, the wheel bearings on both wheels were too tight (in the factory) In both scooters, so that the wheels do not easily ran. With 2 15er keys (one must only times have) eased somewhat and the wheels ran really well. The same with the steering head bearings (Wasserpumpenzange or 32er wrench). The side stands must however be tightened fixed, otherwise they 'turn away' when the weight of the scooter weighs on this. Overall, only minor 'tweaking' of the factory presets. Therefore, unfortunately only 4 stars. All parts are well packed. The drive roller and slow down! very good and seem to be robust. The product is good and I can recommend it.
