Ways not to lock your bike

If there's enough room i just put the bike sideways with those racks

Because there isn't enough room I have to do this

If you can get put the front wheel in the stand and get a lock round the forks, you can stick the bike in the other way round and get the lock through the rear triangle. If you can be arsed to take the front wheel off, that cable would probably be long enough to lock that up as well.
