I'm pretty sure it's going to be a thing for that town, just with Gogoat like
"Hey kid, Tired of walking everywhere" says a mysterious voice, you turn and see a booth this a old guy in it "I know I am, how would you like to ride through (insert town name here) in leasure."
*Character walks over*
"For just 500 (Poke-currency symbol) you can ride around this town with ease." he says
You Irl "Hell yeah, I finally got the bike!".
*You pay the man*
"Haha, great choice, just follow me down this ally"
You Irl "What? Am I getting molested?"
You reach the end of the alley and met with a green fenced off area surrounded by the stone walls of the builings, filled with Gogoats.
"Pick any one you like, oh and here take this!"
*You got the Gogoat saddle"
You Irl "AWEESSSOOOMEEE"
You begin to chase one down in a OCO chicken chasing fashion until you notice one with a slightly different color, holy crap sauce a shiny! You run up to it and try to saddle it, but as soon as you do he kicks you in the face ( I bet he's faster, and maybe requires me to feed him berries or needs a special saddle). You grab a different one, slightly disappointed but still pumped! You race around the town, unable to enter buildings unless you dismount at which point Gogoat runs back to the stables; of course you try to leave town, at which point the old man runs up to you and push you off
"Hey are you trying to steal my merchandise? Stay in (City name here)!" then he mounts it and rides off.
