The Speeder that Obi-Wan is riding is the same type of Speeder in Return of the Jedi.
Durge has the clone commander against the wall. Then Obi-wan starts the convulsions, and suddenly they are in the middle of the room with the commander running off in the direction where the wall was a second before.
(Ventress's ship fly over Obiwan's head)
Obi-Wan: That's not one of ours.
Clone Commander: No general.
(Anakin's ship fly over Obiwan's head)
Obi-Wan: That was Anakin.
Clone Commander: Yes general.
Anakin: Everything's under control master.
Obi-Wan: Under control, I don't think so.
Clone Trooper: General Kenobi, our cannons are being destroyed.
(Obi-Wan looks through a pair of binoculars and sees Durge and his lancer droids)
Obi-Wan: Mount up.
Clone Trooper: Yes, sir.
