I think you're over thinking that 80 pound weight. If you look closely, they have a total of (8) CIM Motors going through (4) Ball shifters. All of those components together (Cim motor @2.8lbs ea, Ball Shifter @2.5lbs ea) weigh just under 35lbs. I also wouldn't be surprised if the battery is included in that 80lb figure too.
Just for reference, if this drive were only running (4) CIM Motors, each through their own Vexpro Single Speed, it'd be ~16lbs lighter, and that's not counting all of the other components that could be removed when the motor count drops from (8) to (4). (Speed controllers, wiring, etc)

No that weight is without battery. We just reweighed, and it comes in at 78.6lbs. Also like I said we have modified the design to lighten the metal chassis frame to about 10lbs.
Yeah, you build robots, so what. But you also build students, and that's what it's about! - DonRotolo [more]
