7 bikes.
Tool storage.
Easy access to each bike.
Side or end door?
Pent or normal roof?

I’ve got a 12×10 that does all that with plenty of room to spare. How ever big your shed. It won’t be big enough.

You will also need another shed. You can never have too many sheds.

I’ve got two already!

One is up top of the hill that is our garden for mower etc
I’ve a 7×4 bike store.
Hoping to flog the bike store…but could keep it.

“my shed is too big”, said no one, ever.

This. Buy the biggest one you can afford and what you can get away with before the Mrs complains.

Said me on Sunday when I was replacing the felt that was blown off on Saturday ☹️ Back to thinking I could do with more space now though😀 Mine is about 20′ by10′ with apex roof and double doors at the end.

Stuff in sheds behaves like gas….

Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form.

So the answer is you’ll never have a big enough shed

We’ve got a 10×6 shed in the garden. Not Using it for bike storage, but no way I could imagine it 7 bikes with easy access to all bikes.
If it’s literally just for bike storage and nothing else, then a 10×8 would probably be OK; preferably with a double door.

Consider using Coroline bitumen corrugated sheeting.
I replaced the clear polycarb roof on my shed with it last Wed and it was really simple to use, is lightweight and should be more durable than felt.

No shed here but do have a double garage. Which is now full.

I’m going to put a garage sized shed in the garden, which should leave the garage for bikes and toys.

I did consider it but didn’t want the expense right now (went self employed in July) Hopefully the felt will last another ten years.
