That would be a great idea. I mean, I am more than twice as fast on a bike than by foot and I can drive more than 10 times as far. Just imagine what Flash could accomplish with a bike
He has a suit that doesn’t melt to his skin. If his people can make a costume, they can make a bike …. Trying to imagine the precision you’d need on those bearings
I was under the impression he was surrounded by the speed force which drops certain characteristics of physics. Things like friction from wind don’t apply to him and I’d guess his suit too?
It would probably depends on what you’re watching or reading. It was a big deal in the show for him to destroy his clothes at the start and then start labs built him the suit that could take it
Think about doing an escort quest where the NPC walks at 25% your speed and how irritating it is to have to keep waiting for them. Now imagine the NPC moves at %0.0025 or your speed instead. If he ever wants to travel with any companions, this might be more to protect his sanity than anything.
I don’t read comics but I’ve hung out with enough comic nerds to pick up secondhand that the speed force and power cosmic are just straight bullshit. They do whatever. Think you found a problem or plot hole? Nah, magical powers specifically address that. Because magic.
In the comic he loses his/the speedforce. Could imagine it was from that, but deep down I know it was just a toy companytrying to sell parents junky toys.
