Based on the anime series *Kanojo x Kanojo x Kanojo* (also known as *Kanojo x Kanojo x Kanojo: Sanshimai to no DokiDoki Kyoudou Seikatsu*), which matches your description exactly, Kakeru ultimately chooses to be with the tough-fighting motorcycle girl (named Mizyu in the series) by the end of the fourth episode. This is shown in the series' conclusion, where each episode focuses on one girl, and the finale resolves with Kakeru committing to Mizyu after exploring relationships with Urara (cute and friendly), Rie (tennis girl), and Hikari (dog-owning painter). The ending emphasizes his bond with Mizyu, portrayed as the most intense and decisive one. If this isn't the series you meant, feel free to provide more details!
