In my Big Wheel in the course of normal use broke the lower, thicker tube the handlebar! Fortunately, I am at this time very slowly down (or almost stood), otherwise would be something very dangerous, and in two respects. On the one hand is a total failure of the handlebar life threatening even at low speeds in urban areas. On the other hand the damage caused by the breach of the handlebar to handlebar or other sharp edges (eg by puncturing the abdominal area) fatally injured. When I reported this incident, Hudora was over the defect (allegedly) surprise and offered me only, the scooter at his own expense (!) Be sent for inspection. Uppity! So after I've bought a micro scooter and Hudora is I no longer see Cent .. HANDS OFF !!!
