Compared to an older HUDORA model in our household of Roller acts "shaky" and carelessly handled. The rear fender is attached by a spring on the scooter. This spring is designed to overall weak, so that the sheet constantly beats while driving on a flat road to the rear and to light up the brake light. The scooter made a total flexes; the new folding mechanism on the other hand had a more user-friendly than the old technology. Even the mounted under the floor box for 4 batteries seemed very cheap and the wiring also appeared not very professional. We have returned to the scooter, as we were disappointed overall quality over the entire impression.
