These two OFF would give you better quality. I believe that with more light, Gyro will work better (same goes for WDR).
Gyro works at night no doubt, the bad thing is the quality degradation at night using Gyro (the image passes from blurry to sharp, and so on). Gyro's efficacy is not the same at night compared to daylight, i believe important factors are scene's darkness, amount of details, camera speed and vibrations frequency). Bicycle moves slowly, there's not an engine creating vibratios, either. "Easy" work for Gyro here.
I would like to know what the WDR option does to the image, since the quality is also affected when the lights go down and WDR is ON. (This happens in many photo cameras that have this feature).
Saludos.
