If we want to take spares into account, then I think something like
S = (2T) + 1
Where S is the number of bikes you Should have, T is the number of Types of bikes you need (which is multiplied by 2 so you have a spare) and + 1 because, you know, more.

I live in an area where I can easily do three totally different kinds of riding. I can ride fast on paved roads. I can do overnight and longer tours on paved roads. I can ride loops on mostly dirt/gravel roads and/or crushed limestone surfaced rail-trails. Therefore i have three different bikes each of which is more suitable for a certain type of riding.
A spare bike is nice to have in case the bike you want to use needs something done to it and either you don't feel like working on it right away or you need to wait to get part for it.
Cheers

Right, there are various ways to end a loop and various types of loops (do:while, set a max for n, etc). This is also why testing is important to avoid putting infinite loops into production. 
To be more on topic my new bike (not a spare), built on a Black Mountain Cycles Road Frame has been sitting idle for a couple months waiting for parts.
While it looks purty in the stand I would rather be riding it.
This also brings up the question of "how much bike storage space do you need?" I can confirm that a 1 car garage is too small.

As far as your garage problem is concerned: a one-car garage might be okay if your number of autos were n = n-1

Well, technically, your excel command would be creating a new value (in a new cell) which is equal to another cell's value +1.
Without a logical explanation and practical application, yes, I do see a problem with violating a common mathematical principle.
I figured some kind of limit would be built into it. Otherwise a simple n = n+1 would not be very useful, would it? (genuine question.)

Which begs the question of the coding concept of n=n+1. As noted, this would appear to create a loop somewhat akin to Kirk's "Liar Paradox" applied against Norman. If the code read: n=n+1; would the program not continually add one to n, readjust, and then add another 1 to n until infinity? One could cap n as noted but what would be the point other than some sort of counter/timer? It would seem that adding 1 to n would always produce a second distinct value other than n ergo: n+1=y.
Perhaps a computer programmer can give an example of how n=n+1 might be used? I can conceive of the coding application abstractly but can't see it's practical application.
It would be funny to create a "How many bikes should I buy" online calculator tool that asks questions designed to help the user determine how many bikes they need and then a field (n) where they input the answer. What ever value the user puts in, it shows one number higher. In that case: n=n+1.

n = 0
while n<10
n = n+1
print(n)
end
The output would be 1 2 3 4 5 6 7 8 9 10
Messing with the meaning of '=' is somewhat rare, but the meaning of the operator '+' is up for grabs.

My current number of bikes is N-3! I periodically fix up some old bikes and we donate them to kids or immigrants needing a way to work. Today, I was relieved of a very heavy, low end mountain bike, a BMX department store bike and a 26 inch Shimano Positron Front Freewheel bike from the 70's. As my son said, "gee Dad, you have a lot of bikes!"
So, since I never rode them, they are not in my official count, but I miss seeing a basement full of bikes, no matter what kinds. Time to go hunting....

So the optimal number of bikes would be 10? (Or whatever number appears to the right of n>...?)

10 used for illustration purposes only. I recently contemplated responding to a tweet asking how many bikes people had and I really have no idea. I'm pretty sure it's less than 30. Majority of them are in pieces.

There are so many types of bikes now that I think most enthusiasts buying an additional bike are getting something different vs a direct spare. A good well-maintained bike should be unlikely to have a mechanical problem 1 day before a big ride. Hopefully the chance of a crash would also be low.

If I have an old bike that I keep around, but never ride, do I include that in my "N" number? Do I count my tandem as half a bike, or as 2? My son's bike is still in my basement, but he has moved away and it hasn't been ridden in years. Do I count that too? What about the one that I am working on, but it's not ridable yet? It is a former and future bike, but not a current bike.
If you couldn't tell, my ride got rained out this morning.

Depends on context.
If bragging to others, include all. Tandem = 2. Possession is 9/10th of the law.
If spouse is complaining about space in garage, default to n = only direct ownership in plain sight. Tandem is technically theirs. So, for equation sake: T = 0.

A Dogma12 with Campy Record and Bora wheels would make a splendid spare bike, or an Argon 18 Krypton Pro. Hmmmm....when you get tired of the Pegoretti!!

Yes, the tandem does take up a lot of space. Maybe I'll just get rid of the lawn mower and snow blower.

As a bent rider, I have both a LWB bent and a trike. So I have the right tool for the job at hand.

For n = 0 to (D-1) rem: D = Divorce
n = n+1
next

N+1 bike is not necessarily a spare for a specific ride. IE DreamRider85 notes a "trip" which suggests at least a longer ride where a MTB & road bike might not substitute well for each other. A touring bike or gravel bike might make a good spare, depending on the wheels & tires.

On (optimal number of bikes)
Cn (current number of bikes)
Dn (number of bikes that cause divorce)
On=Cn+1<Dn

sure it would be 'good'
just not that good if you do not have the money or space for it, or the need (ie you never have rides that you "have to go on")

Don't skimp on the spare bike. In Michigan the 'good' biking weather is only 5 months long.
A spare bike makes sense if you have a breakdown. Repair time could take a day to a week.
The again, sometimes its just fun to change bikes.
