J-Stars Victory Vs. is a fighting game, but at least two characters in the roster can ride bikes(?!). Screenshots show Gintoki from Gintama on a moped and Ryo-san from Katsushika Ward Kameari Park Police Station pedaling on a bicycle to escape a Rasengan / Kamehameha from Naruto & Goku.
Ryo-san also has a rocket launcher, but my money is on Kenshin and his sword. J-Stars Victory Vs. is in development for PlayStation 3 and PlayStation Vita.
Kenshin from Rurouni Kenshin
Gintoki Sakata from Gintama
Ryo-san from Katsushika Ward Kameari Park Police Station
