Katie Holmes Spinning -- 'Cause Tom Has Suri!

Katie Holmes was tight-lipped on the streets of New York this AM ... sans Suri.

As her 6-year-old daughter took a chopper ride with her 50-year-old estranged husband ... Katie went to SoulCycle for a little spinning.

Katie spins a lot ... at least that's what Tom's people say.
