The rings are his main power source for speed. His boost gaugue fills up when he collects them and when he boosts (using the collected ring power) he acttracts more rings. Kinda like how the Chaos Emerald's energies attract each other (and it was stated in the comic at least that rings where a byproduct of the Chaos Emeralds so it would make sense that they'd share the same properties).

Stuff this also explains:

Why rings appear in a straight line.

Why rings disappear when he collects them.

How Sonic can use Light Dash without gear.

There are holes to this theory, but that's what I got for now. While I do believe his speed is natual, I can believe that rings do give the "boost" to his boost. I do believe they hold power.
