OP, I just read that you grew up in the 80s, and it seems you don't currently have any bikes stored or in your garage. Considering you are in your late 30s or early 40s, you are still quite young. If I were in your position, I wouldn't simply buy ANY random bike. Instead, I would invest in a quality road bike that offers a fun, smooth, and enjoyable riding experience, even if it's a used one. The idea would be to keep and ride the same bike well into your 80s, and maybe, 90s. Don't let anyone tell you otherwise. With a mere $200-$300 investment, you can buy a decent used road or hybrid bike. Get a good bike that gives you fun and fulfilling bike-riding experience, rather than just ANY bike. Think long-term, and make that buying decision.
