My old bike I'm working on fixing up. Just learned to replace the tires/tubes and the youtubers make it look way easier than it felt lmao. Still saving/learning/looking for a good hydraulic cleaning/refill/bleed kit. The fluid in it currently is 6 years old but still works well so I'm not in a huge rush, going to be primarily using the green bike anyway.

I spent most of my time on the easiest 4 gears of the 24 combos available. 😰 They really nailed the gear ratios on the ozark trail hybrid for people getting back into it.

Car almost on E, still super windy from the storms moving through the midwest but not too bad. Working on building enough stamina to maintain a steady RPM uphill/against headwinds.

RIP to the wheel in the background though

It's currently all stock and all original parts that came with the bike, hydraulic brakes, tires, etc. In terms of wear, I put about 2000ish miles on it between 2019 and 2020 commuting to and from work.

I'm assuming bike tires follow the same principles as car tires in regards to sitting stationary for long periods and/or sitting stationary while flat. What kind of tires would this need? 700c x 35 with tubes or only tubeless on these wheels?

For the hydraulic brakes are they easy/affordable to service myself? The fluid has never been changed.

Are bearings worth worrying about after 6 years? Or is it only when they make noise/feel off?

I'm not well versed at all when it comes to bikes/bike repair, any help steering me to the right direction is appreciated.

After two test commutes with this guy, I felt it was good enough dig out and salvage the fenders and rack from my neglected old bike.

I would like to refurbish the old one as well but I haven't worked on any bikes before, and this was cheaper than paying someone to do it for me.
