Given that I don’t have any personal gain from proliferating biking as a means of personal transportation, I’d rather consider myself a bike preacher.

A decent bike needn’t be expensive. For as little as 300€, you can have a new bike that’ll do just fine for recreational use and simple commutes. Used bikes can usually be had really cheap, too, but for that you’d best know how to check the components and what to look for.

Race bikes, mountain bikes and pedelecs are a different thing, but those are either specialty sports equipment or luxury items.

Either way, (normal) bikes are easy and cheap to maintain, if used correctly.

That’s an important distinction that too few people understand:

Psychiatrists: medical doctors with a specialization in mental health who can prescribe drugs

Psychologists: trained professionals with an academic degree who provide mental health care by (generally) talking with you

Both are important health care providers, but they generally do very different things, and in a mental health crisis you best have one of each at hand.
