Bikes, yeah, but the computers are portable between bikes. You only need one per rider. I have three bikes, but one computer.
Where "n" is the amount that you currently own, I assume?
I thought it was n - 1, where "n" is the number at which your spouse would no longer be able to tolerate your obsession.
Both are correct so it’s important to maximize for n
marriages have been ended when those don't produce the same value for n
It's a bit like the math on Rubik's cubes, where there were two different proofs: there exists a configuration of the cube that takes n moves to solve, and for all configurations it takes at most m moves to solve the cube. Those numbers finally reached the same value at 20. Hopefully I won't have to go through that much to figure out the right number of bikes with my partner. After I get my frame fixed I'm still probably getting another, and that's how it starts.
