Abstract: A motorcycle anchoring device capable of being driven through asphalt, tarmac, or pavement, and to which a motorcycle can be tethered, thereby providing an anti-theft security when no other mechanism for securing is available. The device is in the form of a solid metal stake designed to be driven through the asphalt or tarmacadam commonly used in a paved parking lot or roadway. The stake includes collapsible barbs or flukes which retract while the stake is being driven into the ground, then deploy after the spike is in the ground, particularly as someone attempts to extract the stake from the ground. The barbs thus provide some in-ground stability, but mainly serve to prevent the spike from being raised. The exposed upper end of the spike is designed to permit secure tethering of the motorcycle to the stake, thereby securing against unintended removal and usage. Once the stake is no longer required, the stake is simply and easily driven completely into the ground.
