B Is an infinite universe compatible with cyclic models?

[TheHeraclitus]

TL;DR Summary

If space is flat and infinite are cyclic models possible? The answer seems intuitively no but I wonder if it's correct.

Cyclic models for reference.
I will take simple Big Bounce as an example of what I have in mind.
In Big Bounce there periods of expansion and periods of contraction which result in a never-ending series of Big Bangs. However if Universe is infinite in extent this would require infinite amount of matter would have to contract into one point but that seems impossible.

The big bounce implies that quantum things cause the bounce while the universe still has finite density. That could happen everywhere in a spacially infinite universe - in the same way that a big bang can.
