I glanced at this question at work, now reading it to find interesting ideas, but also want to share something: six months ago I bought a motorcycle. It was a no-brainer, commuting time is now half compared to the subway and after decades it's invigorating to be back to two wheels, not only physically but also mentally.

Maybe not very niche, but you'll quickly find there are many sub-cultures around biking (some of them very friendly) and an endless variety of interesting tech: engines, suspensions, electronics, injection mapping, IMUs, gear materials, GPS... routing is its own rabbit hole.

It's not necessarily very expensive. A middleweight bike that will take you everywhere can be bought for less than 10k. Add a grand more for gear and insurance.
