LaDainian Tomlinson and Antonio Gates just did their best Santa Claus impersonations ... gifting an entire room full of kids with brand new bicycles for the holidays!!!
The two Chargers legends hit up an L.A.-area school earlier this week for the sweet gesture ... and video of their surprise visit is AWESOME.
You can see in the footage, Tomlinson came out to the crowd of kids first with a new set of wheels and a Chargers helmet -- while Gates followed suit with a ride of his own shortly after.
It appeared the Bolts duo was only going to give out the two bikes -- but, when an official announced EVERYONE would be getting one, the kids lost their minds!
