Yes, low center of gravity makes the bike handle quicker, but it can fall quicker too. In my experience what makes a bent easier or harder to learn is how far the seat is reclined. Sitting up straight isn't as comfortable, but the brain has an easier time acclimating in that position; while reclines of <25 degrees can be a challenge at first. Whenever possible, I recommend to new riders that they start out with the seat as upright as they can comfortably get it, and gradually lower the angle as they get used to the bike.

Unfortunately, too large a percentage of bent riders seem to revel in the stereotype of gray/white beard, pot belly, sandals, and a flag. I have none of those things, although I am slowly acquiring white sidewalls. That's OK; I want the kids to know they've just been passed by an old man.
