Also worth mentioning bicycle related is the lifework of Sheldon Brown: https://www.sheldonbrown.com

Not fancy looking, but very interesting.

Sheldon Brown is a great resource for bike information - lots of no-nonsense advice and explanations though it is getting a bit out-of-date now since his death. A particular favourite of mine is his chain cleaning method: https://www.sheldonbrown.com/chainclean.html

That would be something I'd personally consider out-of-date with modern chains. Apparently that makes me a "Lazy, careless cyclist" as I would never use grease on a chain. Nor would I ever follow this insane method of cleaning a chain.

Guess I'd consider myself to be an efficient cyclist, which may be construed as "lazy" by some.

edit: reading onward, he claims "Serious cyclists, who value performance..". I wonder what he considers "performance", because it sure appears he didn't consider or measure drivetrain efficiency.
