Electric-Assist Bike Repaired

I am happy to have my electrically assist bike repaired.  It cost a bomb with the guy charging me transport as well.  Unfortunately, there is a special tool required and he has a subcontractor who does the work for him.  He did not want me to know who it is so that I am tied down by him.  Anyway, I will use until it breakdown again and maybe retire it if the cost of repair and maintenance is too high.  Now we can get anything from internet at a reasonable cost.  So replacement cost has come down.
