All I do is lube mine and its been a gem for years now. People preach that there is this whole maintenance regimen and you have to be this hobbiest watchmaker to deal with bike gear ratios and such and such, yet most bikes just sit in the garage with the lube that came on them from the factory and work fine. Go to a college and see all the 50 year old 10 speeds lined up in the racks. If you have a 50 year old piece of hardware in such high use that doesn't seem like its this unreliable untrusty system to me, quite the opposite. Especially compared to like anything else in transportation, like a car that might incur thousands in repairs over its life. How many 50 year old cars are parked at the college? How many cars are even over 25? Even a skateboard is less reliable; take a skateboard out in the rain and the bearings are fouled and the deck may even warp. You can even get bike tires that make flat tires practically obsolete short of hammering in a nail because they use kevlar like a bulletproof vest. Literally bulletproof tech.
