Cycling Equations (or How Many Bikes Do You Need)

I was talking with a friend the other day and the old question of “How many bikes does a cyclist need” came up. Well, we all know the answer to that is expressed as the equation n+1, where n = the number the cyclist currently owns.

We had a bit of laugh about that but he then identified the other equation to answer the same question- s–1, where s = the number of bikes at which point the cyclists significant other kicks them out or leaves.

That posed the conundrum, how do you identify the point where n+1 and s-1 reaches critical mass?

At this moment in time, in my case, n=4 but, until about a month ago, n=5. Now, did n=5 become n=4 because s=5? Or did n=4 arise because the current funds for other projects =0 and I needed to raise some cash?

Only SWMBO will be able to answer that and I ain’t asking.
