Bike action/stunts/etc is nice, but one can go overboard with it. While I myself like the bike action in Kuuga, having Godai ride atop parked cars, up and down stairs, etc starts to look excessive after a while. Now need to dazzle the audience that much.
I actually say the scenes of Godai riding to the battle in ep. 4, as opposed to the bike battle itself, was one of the best bike moments in Kuuga. Those scenes really gave off the "KR is back" feeling.
