I think a Pikachu from Safari.
Safari Zone - the area where you need an Acro Bike to get to.
There's a bike shop in the city with the electric gym. Go inside, talk to the shop owner and choose your bike (mach or acro).
the stuntbike in ruby is called an acro bike and you can get it in mauville city
You'll find it in Mauville City. There are two types of bikes that you can get - the Mach Bike and the Acro Bike. The Mach Bike allows you to go muddy slopes and cracked floors, while the Acro Bike allows you to perform tricks.
You evolve a Phanphy, In Safari Zone Acro Bike Area, at level 25
You can find Heracross in the Safari Zone, with about a 5-10% chance of finding them in one of the areas accessible with an Acro Bike.
You can catch pikachu by going to the Safari Zone in Ruby and then go into the grass in the safari zone and you will find a pikachu edventually. First you need a Acro Bike from the Mauville bike shop. Then you need a Pokemon that know's sweet scent (Tropius). Then you go to the Safari Zone and use the Acro Bike to go on the metal pole that you can not walk on or use the Mach Bike on. Then you go to the far right corner and use sweet scent in the grass. You will soon find a Pikachu or Raichu.
You can find it on mauville city, near the Pokemon center (there are bikes outside, it's really easy to find)
Yes there is. After putting Pokemon in the Daycare near Mauville or Vedanturf, go back to Mauville and get the Acro Bike from Rydel's shop. Then, go to the sandstorm near Mauville and find the Waterfall near the back entrance. Get on the Acro Bike and keep trying to ride up. You can not get up but everytime you try, the Pokemon in the daycare will go up in exp by 5, do this for a while and your Pokemon will really level up, especially lower leveled ones. Note: This can only work with the Acro Bike, the Mach Bike will ride straight up the waterfall. Note: You will need the Go-Goggles for this. Note: There are no more notes.
You can also put your Pokemon in the daycare, get an acro bike and find a mud hill (those things you need a mach bike to get over) put some thing on the button so that you keep riding into the hill, now you just leave it on overnight and your Pokemon should be a much higher level. *When your Pokemon are in the daycare they learn new moves so make sure they aren't going to learn any sucky ones*
You can find Phanpy in the Safari Zone. You will need at least $500, an Acro Bike and a Pokemon that knows Sweet Scent. Fly to Lilycove and from there travel to the Safari Zone. Okay, you'll need the $500 to get into the Safari Zone. Once inside, travel up until you see the bridge that can only be travelled over using an Acro Bike. Ride the Acro Bike over the bridge and continue to go upwards. Finally, once you are at the furthest upwards that you can go, find a patch of grass. Now use Sweet Scent until a Phanpy appears (You can simply walk around but using Sweet Scent prevents you from using up all your steps in the Zone so it's easier). Phanpy should appear after a few tries. It is in safari zone.
