The "drag surface" is big, though the speed is also very low, so the effective drag is very limited. The "energy loss" due to an increased drag coefficient is the 3rd power of the speed the subject goes. So, with these low speeds, hardly any influence of an increased frontal surface.
Not to say, I don't have the impression to be blown off my motobike (chopper type) when driving 50 km/h. Speeding up to 80-100 km/h makes a great difference and with 160 km/h it's a challenge to not be left behind by the motobike (the drag-force is the square of the speed).
