I bought a used cargo bike that has been standing for years, it did not have any controller so I ordered one from Ali Express, I have got everything to work but the PAS as it is now, but it sound terrible when wheel have load, anyone know what I should look for or grease up?
Without load everything sounds great!
As for the PAS I guess it is broken
Thankful for any ideas 🙂
