I lock my 4 bikes together in my apartment because I don't trust someone not to break into my place while I'm gone and take them. Because there's been a lot of probs in my neighborhood with break ins. I figure 4 (3 if in using one) bikes hooked together with multi Locks and hooked to a large entertainment center or desk they'd be hard to take. Id rather they take my tv/ble ray and so on than my bikes
