Comment to video if you want me to check coupons for some specific bicycle you like from that store that is not mentioned above, I just could not be arsed to add them all here.

Bicycle parts mentioned in this video

Hydraulic brakes
They do their job well, arrived with oil and everything needed to cut the line and put it back together, only allen keys and knife needed for that.
You will need to buy a new cable to connect brakes to controller, they are sold in same place. Maybe you can ask seller to do it for you.

Alternative Hydraulic brakes.
Have not tried those but they come with right cables and look identical overall, just different labels.

Mineral oil for brakes
Ordered because though brakes above would require it, because it is liquid it took a looooooooong time to pass all the customs, like maybe 2 months in total, I suggest to find it in stores near you.

Brake bleed kit
Good set , but again, not mandatory.

Air suspension
165mm is the size, It requires pump to set it properly to your weight.
Order single chamber tho, I ordered double one and its pointless, it requires rider to be 100+kg to bring any benefit and even then its questionable.
Apart from pressure has nothing else to set, works great after 10 months, no complains, nice and soft now.

High PSI pump for suspension

Mechanical brakes
Ones I ordered, only good for front brakes, not recommended for rear.
One came bent to unusable state but seller sent another one for free.

Mechanical brakes I would buy if I had to start all over. (cheap and good)
