Mountain bike stands

Cameltrail

We recently brought our sons mountin bikes so now have three. We require a floor stand to put them in in the garage, as they tend to throw them against the work bench. Does anyone know where we can get one from? The only one I have seen has narrow gaps in it to put the tyres in. Thanks.
