What Space Marine chapters (Loyalist or Traitor) specialize in using bikes aside from the Dark Angels or maybe the White Scars?

I believe that the Red Corsairs, led by Huron Blackheart, used Bikes a considerable amount. They had an Apocalypse formation if I recall correctly.

Emperor's Children, maybe, because of the possible speed that would make them feel high.

Dark Angels successor chapters also maintain Ravenwing style formations, I believe.

Any Codex chapter will have a company that specializes in bikes. The 6th Company is a reserve company that trains primarily in use of Bike Warfare.
