This is a great way to tidy up your bikes in the shed or garage, having looked at various models this appeared to provide the widest gap between bikes, needless to say they are a snug fit. The bars are wide enough to take my mountain bike front wheel (not rear)which is a bonus.
Care is needed for children's bikes, a 20" wheel won't fit as the bars foul the axle and this does not allow the tyre to rest on the ground, similarly some 24" wheels don't fit either. My eldest daughter's mountain bike is ok but my younger daughter has a road bike (drop bars, road tyres etc) and again the bars foul the axle.
Other than that it's a good product at a good price
