How to deal with Hoenn's bike problem

[Exemplary]

Due to Hoenn's bike mechanics, many areas are incompatible with the current (bikeless) engine.
Ride-only paths would both make ride a useful HM and make recreating the gen 3 maps easier (replacing bike tiles with ride only tiles)

Also for various cycling roads, they could let you "rent" a ridable pokemon or require you to have one.

We were just gonna have the game pretend that ride is a bike for all purposes.....
If anything we might make a destinction between "fast" and "All-Terrain" mounts for the purposes of having the fast tiles and the legde climbs but we were always planning on having ride=bike
