> It applies to any bike

On a bike with derailleur gears, every time you change gears the derailleur will add some slippage so you won't get this effect.

> The easiest way to achieve this is to make the number of links in the chain prime

The chainring is fixed, but you might need to add or remove a link in the chain. In practice it seems more common to make the chainring have a prime number of teeth (53 or 47).

Good point about the derailleur, I hadn't thought of that!
