Slab base is a good - plenty of weight there if you fancy some anchors for the bikes...... 600x900's are barstewards though, especially when you drop one on the end of your finger......

That's not a big shed, there's little point in going to a lot of trouble. I'd just put a line of slabs at each end and in the middle leveled on the ground, it ain't going to go anywhere.

I agree with fossy, used to build bases for oil tanks and some dry mix sharp sand/cement base a few inches thick with some nice big slabs laid and spanked flat, leave for a while, job done.

Don't forget to bury an anchor in the ground under the slabs that you can use to chain your bikes down to.
When I did a concrete base for my shed for my motorbike I laid some reinforcement mesh with a 25 ton D shackle hooked onto it. The concrete was poured on top and I now have a 50mm diameter steel bow poking out of the base to lock onto. I set the shackle so that it was between the bike and the adjacent brick wall to make it harder to get at.

Bollocks. Spend a day mixing, pouring, tamping 4 cubic metres of concrete.
Your shed won't be any better for it, but you will be.

Night train's post about the shackle wasn't bollocks, BTW. Sound advice, that.
the other option is to dig 4 holes - one at each corner, and pour in concrete with a two 12mm threaded rods cast in to the top of each. Concrete to be about 1 to 2 inches proud of the surrounding land. Put 2 nuts and washers on each rod and level. Cut treated timber joists (if it's a six foot long shed then 6x2 will do) to the length of the shed plus an inch, and drill holes for bolts, bolt down joist, sinking nut into joist, and crop bolt.
Span between the joists at foot intervals with joist hangers and more joists of the same type and hey ho! you have a timber grid. 22mm wbp ply on top of that and then your shed goes down on top of the ply. The disadvantage of this is that the shed floor is raised, and the advantage is that it is dry. You can even insulate between joists by running sufficient strawberry netting across and down between the joists and loose-lay glass wool.....
If you need a ground anchor simply put a fifth concrete pad in cast in a chain which will come up through a small hole in the floor.

If you just use a frame then don't forget to use a weed suppressing membrane to stop weeds growing up under the shed.
