Abstract: A one-sided spring-loaded arm for the front wheel of a bicycle consists of two parts (1,2), of which one is springing, and further, one of them is adapted to attach the front wheel of a bicycle and the other is adapted to be attached to the handlebar system of the bicycle. Part (2), which is adapted to attach the front wheel, is joined with part (1) slidingly in the direction of the longitudinal axis of part (1), as well as pivotally around this axis with a position fixation, as well as tiltably, with the axis of tilt lying in a plane transverse to the longitudinal axis of part (1), which is adapted to be attached to the handlebar system of the bicycle. Part (1), which is adapted to be attached to the handlebar system of the bicycle, may be spring-loaded and it comprises a supporting part (1.1), on which there is an auxiliary member (2.2) arranged slidingly and pivotally and positionally fixably.
