#Tim was the only one unaware of the prank due to leaving last and not seeing the other vehicles

Okay, hear me out

Imagine with me. Batman, pedaling as fast as he physically can, on this children's bike, chasing a rogue. It was the only option he had, and he knows he'll be made fun of later by his kids, but he has a mission at the moment, so he can't be bothered to care

And then passing him is Nightwing riding a segway (Nightwing themed, of course), Red Hood wearing heelies, Red Robin on his normal motorbike, and then Damian on a little classic child tricycle.

As it turns out, someone (Alfred) had hidden all the normal vehicles for a prank war, left only Red Robin's motorbike to frame him (because who would suspect Alfred??), and was currently receiving pictures from Barbara to add to a photo album.

Alfred knows he's safe from retaliation, even when they figure out who did it.
