I bought a simple spin bike thirdhand. Guy who owned it before me got it from a gym. You twist a knob and it increases pressure on a leather brake. Its built like a tank.
Its great and like you say, if I wanted I could just look up spin videos on youtube for free.
Why would I bother with a Peloton?
This Land is Your Land is also not the patriotic song people think it is. At least, not in the way people think it is.
