from the creators: 'In-Lock' works as a ground anchoring system to secure motorbikes or mountain-bikes to soft ground. To use, one takes it from its casing and screws it into the ground using the turning bar provided. Once in the ground, any motorbike or mountainbike can then be locked to it through the hole in the main body by using any design of chain or lock. Once placed through the hole, it prevents anybody being able to unscrew the 'In-Lock' from the ground. Physics ensures 'In-Lock' cannot be pulled out of the ground by using force, even in the wettest conditions.

from the theives:i don't believe in physics.
