Hi!
If you have Chinese Ebike like Engwe, Samebike ect.. you need this part if your old one is bad. It is for the rear tilting mechanism. 8 needed to change the old ones. I printed from Igus iglidur I150 which is a self lubricant material, I think this part need a high wear resistance so dont use PLA,PETG and other soft materials. Maybe ASA or ASA is also good but if you have any Nylon material than use that. Be careful when you loose the screws because those are glued.
