A BMX starting gate includes a frame with a gate opening; a slider bar attached to a bottom surface of the frame; a gate pivotally attached to the frame at a connection point such that the gate aligns with the gate opening; a linkage bar attached to the gate proximate to the connection point; a lever attached to the linkage bar distal from the gate, wherein both the linkage bar and the lever are slidably attached to the slider bar; a strike plate attached to the lever distal from the linkage bar; an electromagnet attached to the frame, wherein the electromagnet is positioned to releasably engage with the strike plate; and a spring connecting the gate to the slider bar. Activating the electromagnet causes the electromagnet to engage the strike plate and cause the gate to extend outwardly from the frame. Deactivating the electromagnet allows the spring to return the gate to a non-obstructing position.
