Okay so my friend needs to find an anime he likes as a child he described it as "An anime about motorcycle riding bad asses who wear cyborg looking helmets, one colored red, and one colored blue, and they fought and there was this albert einstein looking guy who lived under ground who could build robots and he built the main character etc."
he said it was played once at the later end of toonami for 15 minutes just before adult swim aired
he says its the first anime he saw and was what got him into it and saw it probably sometime between 2001 and 2006

he says hes will legitimately suck my dick if I find this and I'm gay (obviously since I'm OP) and I need this plz help

also pic unrelated I didn't have anything relevant cus I don't know the anime obviously
