I am curious to hear about how well you secure your bikes over night, particularly those who live in apartments. I live in an apartment and have a parking spot in the carpark with a security door but no lockable individual garage. The space i have is limited however i have come up with the idea of using a race stand bolted to the floor to keep the bike upright and minimise the space the bike takes up and chain the bike to a seperate floor mount also dyna bolted to the floor. I also have a dirtbike and a car so the need to minimise the space used essential. I was intending to do the same with it. Is there a cheaper way of chaining the bikes to the floor than forking out $140 each for the floor mounts i see at the bike shops? How do you secure your bike?
