Batman Sled props were a piece of fictional merchandise from a Batman-themed Gift Shop in Gotham Plaza. A scene showing a father purchase one for his son was going to be shown. The Tattooed Strongman was going to weaponize this sled instead of a regular one to assault the salvation army santa. Furthermore, the circus strongman was going to chase Alfred and a little girl with it, before having a Batdisc fired at his head from the Batmobile. Batman would remember this when killing the man with Thin Clown's Bomb later in in the film. The gift shop was going to be destroyed by the Firebreather, who was burning citizens alive, also during the Lighting of the Tree Ceremony. Batman used the Batmobile's jet burner to set the man on fire, also eliminating him in a brutal fashion compared to the defeat of other gang members.
The original Daniel Waters script featured heavier sub themes of Batman's impact on society, including Batman inspired gangs. The sled is another example of the Red Triangle Gang using Batman paraphernalia against him and the citizens, like the Super-Batarang, turning the Batmobile into a bomb and using a Bat O' Ride during its hijacking.
