Get onto Cycling Road without a Bicycle!
Okay, so you may have deposited your Bike in your PC or never even bothered to get one, and you really can't be bothered to pick it up so you can get on Cycling Road.
There's a simple solution. When you enter either of the guardhouses that separate Cycling Road from Celadon/Fuschia City, walk so that you that the counter is right next to you. When the guard stops you and says that you need a Bicycle, keep on pressing Left on the D-Pad and after he's finished speaking you will walk past him anyway.
A very convenient and useful glitch!
