A bicycle rack is provided for connection to a vehicle, and especially a bus for the transport of a bicycle. The bicycle rack has a frame pivotally connected to a bracket which is connectable to a front of a bus. A pair of elongate cradles traverse the frame of the rack. Each elongate cradle is capable of receiving a bicycle. Each elongate cradle includes a rear wheel cradle and a front wheel cradle. The front wheel cradle has a spring operated wheel lock. The wheel lock includes a rotatable armature which overlays and holds the front tire of the bicycle in a locked position. The armature is actuated by the weight of the front wheel or by the manual activation of an adjacent handle.
