Mikoto Shinozaki
1st year student and the third member of the schools cycling club. Originally living a quiet boring life and getting bullied daily by the upperclassmen. Until one day when Yuki Fukazawa asks him to join the schools cycling club. He rejects this proposal at first as he doesn't remember how to ride one. But wanting to impress Yuki he tries to train in secret and during this (short) time he starts to actually like bicycles.
Yuki Fukazawa
1st year student and Mikotos big crush. She is Yosuke's sister. She was the one that introduced Mikoto into the cyclying world. Although she normally acts cold towards Mikoto there are some hints as to her true feelings towards him as the story progresses.
Yosuke Fukazawa
3rd year student and the captain of the schools cycling club. Has been bicycle racing since his early childhood, though not very much liked by his teammates as no one was able to keep up with him. The exception being his friend Koichi. Both Yousuke and Kouichi ended up leaving the cycling club and later on started their own. He excels in downhill racing.
Koichi Terao
3rd year student and the second captain of the schools cycling club, he is the childhood friend of Yosuke and 2nd member of the cycling club.
Takeshi Yamato
1st year student in the same class as Mikoto. When Mikoto first sees Yamato riding, he doesn't realize who he really is and decides that Yamato is someone he must defeat and later on befriends him still not realizing his true identity as the "black clothed rider" as yamato always wears all black when he's out cycling.
