Welcome aboard
I'm from Chico and you have found a great place to learn and share ideas. Like you, bicycles have been a part of my life since I was a pup. When I was in Jr. High (1966), I stripped down a bike and put on the largest knobby tires I could find and that was my Jeep/bike. On my first adventure, I pushed the bike up a somewhat brushy hill in Riverside, CA, planning on doing a little downhill, what happened next was that my chain came off, maybe teased off by a brushy stick, and down the hill I went at a seriously increasing speed since I now had no brakes. Fortunately, the large bush I aimed at slowed me enough that it didn't hurt when I hit the ground. That was the last time I tried that, too bad I didn't have the where-with-all to explore the idea of mountain biking since this was long before that venue. Motorized bikes are really fun and very nostalgic since the first motorcycles, were mopeds. Welcome aboard!
