Load support with a load bearing part and a supporting element

The load support (10) has a support element (70), which is displaceably guided by a guide unit moving along the longitudinal axle direction for supporting the load, particularly a wheel of a bicycle (90), such that the support element is adjustable in a longitudinal position along the longitudinal axle direction. The support element is fixed to a load bearing portion (30) by a holding unit. The load bearing portion is mounted by a slide bearing or rotary bearing movable corresponding to a base support (17), such that it is movable between a non-usage position and a usage position.
