How much space for to store 6 adult bikes

i thought maybe 2.2 deep and between 2.4 & 2.8 - maybe alternating forwards and backwards so the handlebars dont get tangled? With 2 full width opening doors?

Wall hooks, alternating heights so handlebars avoid each other, that way the space is a bike height deep, three and a half handlebars wide plus frame widths, and a bike and a bit high.

Lifting at least 3 of the bikes wouldn't be possible

Look what i found!!

Of course I'd need to find someone who had one to see how easy I'd find it to use

& apparently DH's bike could be stored on a bit of kit that turns it into an exercise bike! Thus reducing the number of pieces of gym equipment

Does that mean im down to 3 bikes? As we are discussing selling 2 of the 6 bikes as well (or possibly 3 and buying 1 more suitable one)
