SB-913V Side Basshar

The SB-913V Side Basshar (サイドバッシャー Saido Basshā?) is Kaixa's support mecha, and can transform into either a sidecar-type motorcycle (Vehicle Mode) or a bipedal walker-type battle Mech (Battle Mode). Neither form offers any significant protection to the driver.

Side Basshar
Like the Autovajin, the Side Basher also has limited A.I. and is programmed to help and protect the user of the Kaixa Gear. On a side note, Side Basher's A.I. seems less advanced than Autovajin's, as rare are the occasions where it is seen acting on its own. The Side Basher is the only Rider support vehicle that survived through both the end of the series and the movie, although its user did not. Its ultimate fate in the two cases is unknown however.
