I made some changes, installed 3spd rear hub and put straight handle bars, also put new tire to rear as one there earlier was quite worn, but now I don't know if it is bike for bad terrain or bike for tarmac, maybe I need to buy new tire that is more suitable for rough roads
I did took 3spd hub to many small parts, cleaned to very shiny and then put new grease in bearings and brake, also used gear oil for transmission part.
It works now as if it would be new, really good brakes and gears shift really well, even when pedaling, quite amazed how well it did go as I have no experience from such jobs.
Also moved saddle bit forward and it made big difference, on gravel road that is now really good, when I get new tire to rear that is more suited for use I'm planning for this bicycle, then it should really be something that I can use as my other bicycle is for tarmac only.
In this condition it weights 15kg, does not look like that, but it is what I weighted:
