The carrier does not work with a center stand on the wheel, as the wheel would have to be characterized tipped too far from the wall.
Even the side stand can interfere in one direction.
Also you have to learn that the wall is inclined toward pedal arm should be up, as a freewheeling makes good but the learning effect occurs after the third time of even a ;-)!
Assembly time for lying ready tool under 10min !!!
