Abstract: A bicycle side-suspension system for maintaining the bicycle in a generally upright position on a roller type training device while still allowing some movement and tilting of the bicycle to simulate outdoor normal riding conditions. The support system includes a single tube adjustably connected within a exercise room in a side vertical position fitting all rooms and ceilings, with suitable mechanism being provided for easily connecting the side-suspension device to the bicycle to effect such support function. The side-suspension system permits a range of lateral movements stretching across the surface of the rollers, for example, as it is being ridden on the roller type training device while still providing substantial upright support for the bicycle.
