I love bikes and was going to comment about them so I'll just tack on to your comment.
Built a single speed out of a cheap, used frame with some spare or cheap parts and it has been going strong with little maintenance for 14 years.
Also have a long-tail cargo ebike that I got this summer and already have over 500 miles on it. It can be faster than driving a lot of times on top of being more fun for me and my kids.
And to top it off a full suspension mountain bike (2018 YT Jeffsy) which I get out on about twice a week and is really great for my physical/mental state, and has a huge skill ceiling so there will always be something to strive to get better at. Just got back from a weekend off riding an area with huge granite boulders and slabs with a few friends. Really fun to attempt features that made us a little uncomfortable and build skills/confidence.
In my university, one Saturday per year they would allow us to take whatever we wanted from the abandoned bikes junkyard. I can't remember having more fun. Just bring a box of tools and some new chains and cables and build bikes the whole day.
Rode the Katy Trail a few weeks back. I loved it but after 6 days on the saddle my ass hurt so much that I'm trying out recumbent trikes right now. (Got a used one off Craigslist.)
