Welcome to the site and the hobby.
I'm age 71. I bounce pretty well when I fall off the bicycle, especially as I wear long sleeve polyester/cotton work clothes and poly $1 work gloves. Closed walking shoes. No road rash.
I haven't fallen off the cargo bike left in the 7800 miles since I bought it. My weight stabilizes the front fork some. Not enough trail on modern bike forks to be stable.
I went over the handlebars of a Pacific & a Diamondback mountain bikes, and a Huffy Savannah cruiser, 5 times since 2008. Hit my chin every time. I broke it the last time @ 25 mph. I now have found a helmet with a chin guard and a lot of vents, a Fox rampage. I tried to find a chin guard before the last accident, but all I could find was sealed motorcycle helmets. The secret search engine term for chin guard bike helmets is "downhill mountain bike racing helmet". I've never raced a bicycle, but I ran in a few 5k & 10k runs in my thirties where I came in 578th or something. Slow & steady, still on the bike after 64 years.
Electric tricycles tend to fall over if turned too fast. Like above 6 mph or something on the typical schwinn grocery getter. There are safer tricycles, that have two front wheels and one back, that tilt into the turn. Those cost about $5000. See the tricycle forum under bikes by type below.
Happy riding & shopping.
