Another newbie here, on a bike after decades off. I'm still trying to figure out how to get
both my feet into the straps/cages

. Gravity dictates that their natural position is hanging upside down. I can generally get one foot in before take-off (still a bit awkward, but hey, I'm beyond using my hand now), but for the life of me, I can't get that second one in! I'm not going to stress about it too much; too busy familiarizing myself with more important things like brakes and gears and not running over pedestrians. It's just funny how, even though my general ability to ride a bike has remained intact after all these years, the "naturalness" of it hasn't quite come back yet.
