> The cost of luxuriously maintaining a bicycle is about $100-$200 annually
That's if you fix it yourself. I spent <$100/year on maintaining my bike.
Changing brake pads at a bike shop cost upwards of $60. Wheel truing, probably >$200. Attempting to buy brake pads and refusing brake pad changing service usually involved a stupid long conversation with them to convince them you didn't need service, and they would price gouge you on the brake pads. With Amazon it cost me a grand total of $8 for the new pads, shipping included, and not having to convince anyone that I'm competent at fixing my own bicycle.
I once had a pedal stuck in my crank and just needed a longer wrench with more leverage to get it out. Damn bike shop wouldn't sell me the wrench. They wanted to do it themselves and charged me fucking $40 for TWO MINUTES of work. WTF. Needless to say I never visited that shop again.
