Sonic Riders New Dimension is the 4th game in the Sonic Riders Series.
It begins with Tails finding a small red jewel called a Power Ruby. Rumor has it that when you hold it to the sky, you warp to a new dimension. "HAH!" Sonic laughed. "A New Dimension? What a joke!" Sonic,Tails,and Knuckles are in a vacant field. "It isn't a joke, Sonic!" Tails said. "Yeah, like we're supposed to belive that!" Knuckles exclaimed sarcastically. "Grrr..." Tails growled as Sonic and Knuckles were laughing their heads off. "THIS IS SERIOUS,SONIC AND KNUCKLES!!!!!!!!!!!!" Tails screamed, with a tight grip on the Ruby. He then accidentally held up the Ruby to the sky. "Uh-oh..." Tails worried as the earth shook. "Wh-wh-what's going on, Tails!?!?!" Sonic said. "It's...happening! We're going to a new dimension!!!!!!!" Tails screamed as the world went black for a moment, then turned back to see no Sonic Tails or Knuckles. Then... "Ooof!" Sonic said as his face hit the ground. "Woah.... I guess Tails was right." Sonic looked up to see three familiar faces. "Well, Sonic the Hedgehog. It's, well, been a while..." the first figure said to Sonic. "Heh heh..." "No...." Sonic said. "JET!?" Yes.... it was the Babylon Rogues, Jet, Wave, and Storm. Tails got up. "It's YOU!" Knuckles threw his fist close to Storm. "Not YOU again!" It turns out they were all looking for the Rubys. "There are only 10 that exist?" Sonic questioned Jet. "Hmm hmm." Jet replied. "Tails! Where's that one you had?" Sonic asked. "I--- I-- I LOST IT!!!!" Tails said. "WHAT!?" everyone said but Tails. "We lost ours too!" Wave said. "Well, we aren't giving up!" Sonic said as he,Tails, and Knuckles rushed off on their EX Gear. "We have to get them before they do!" Jet yelled as they took off as also.
