As indicated in other reviews and countless comments on the Internet, the Achsverschraubungen solve both front and rear. After just a few days and short trips, I noticed that there is front wheel wrong and grinds because the Achsverschraubung was widely rotated. In control at the rear wheel was missing even one-sided attachment and the axis was willing slipped a piece outwards. A dangerous fall spared us by chance, fortunately. I have returned the scooter and I'm still remained sitting on the shipping cost, as it was not that color of the scooter directly from Amazon. The facts I wrote with a request for comments on Hudora. In response came a clear prefabricated email with much blah, among other things, that this is not a toy, that the screws are fitted with fuses (can not be!) That the connections should be checked regularly (aha) and that to wear protective gear (I understand again). Of course I was very upset because of the cost and the considerable time required, but in any case I can only strongly advise against buying this scooter, which is really dangerous!
