Abstract: A bicycle rack is configured to support a bicycle in either a substantially horizontal orientation or in an upright, substantially vertical orientation. The bicycle rack includes pivotally and slidably coupled first and second frame members, and three support assemblies. Each support assembly includes a first support member defining a generally upwardly facing bicycle support surface, and a second support member. The first support members are height adjustable to vary a height of the bicycle support surfaces above the plane, and to provide a three-point bicycle support platform configured to support a bicycle in a substantially horizontal orientation. Each second support member includes a releasable clamp member for supporting a bicycle in an upright, substantially vertical orientation.
