We keep bikes, scooters etc in the garage. There isn't really space in the garden for the kids to ride them there so it's not been a problem getting them out.
The little tykes car and rocker stay out in the garden uncovered.
For smaller stuff, balls skipping ropes and so on that we use inthe garden I've been looking at the plastic storage benches. I'm hoping the kids will be able to get stuff easily and I will have somewhere to sit with a cup of tea by the climbing frame.
The yardstash tent thing does not look like it would last long here. I can't imagine the kids managing to lift stuff over the lip of the groundsheet (they always trip over the one in our tent) and would probably rip it. They are also not great a zips (again they often get our tent ones stuck)
