Generally any size goes for 26" bikes, i personally think the longer the better, although if you take this approach with a 20" bike you'll more than likely run into issues with clearance as the 20" bike is smaller.

Some people think the difference in sizes is noticeable in power and the ability to gap etc, but in reality it isn't. What you might find is that with longer or shorter cranks your stance with the peddles level might feel more natural depending on your size. Though take into account at most the difference will see your feet 4cm further apart.

That said though i have seen 175's run on a mod and 160's run on a stock and in both cases the riders were fine with them.

By sizes do you mean lengths?

The answer is yes if you mean lengths. i think it varies from 158 - 175 mm length of crank arms. My old monty 221ti crank arms were 158mm.
