Good to complete the equipment of children

We have a carport, where a lot of things the children are (bicycles, Dinocar, etc.). The combination lock is not suitable to deter theft entirely, but who steals quite normal children's bikes?
However, it is not unheard of that a bike stolen and a place has been further thrown into the bushes. And it is precisely for this ranges from only lock once. And the children can not lose the key, only the code you need to remember. For such purposes, my strong buy recommendation!
