Mobile roadway unit for two-wheelers

The unit has two ramp arrangements (8a, 8b) connected with a base unit (2). The ramp arrangements are adjusted from a transport position into a use position. Inner and outer ramp surfaces (11a, 11b, 13a, 13b) of the ramp arrangements and a track surface (7) of the base unit form a passable trajectory in the use position of the ramp arrangement. The base unit is designed as a trailer connected with a towing vehicle. The ramp arrangements are arranged along a longitudinal axis of the base unit.
