What does Usain Bolt's Bolt ability do?

A Temple Run 2 update was just released, which added Usain Bolt and his mysterious Bolt Power ability to the game. This is a thing that happened.

Irritatingly enough, he's not available for coins at all. Unlocking him is a straight-up in-app purchase ($0.99/regional equivalent), probably for licensing reasons.

So before considering a purchase, I'd like to know: What does his unique ability do?

Solution 1:

It combines speed boost with coin magnet:

Of course, being Usain Bolt, he has a unique power-up that combines the speed boost with the coin magnet; we're not sure there's a better analogy for his lucrative life.
