Bike repair stuff is done. Oiled chains on both bikes and switched the pedals on one of them. The seat is still the same though. I will need a new seat-tube for that one tbh. The screw holding the seat in is just round. I can't get it off.
So I will spare me some hassle and order a new tube so all this gets easier.
Shout to seth from berm peak this little section from a video makes swapping pedals so easy. No confusion just ez. (It helps when pedals are marked R and L for sure though)

Though the vid has other useful easy tips on how get the back tyre in and out easily and how to get a chain on that fell down super easy.
