Wow, I thought My 2015 CITY COMMUTER had a MOTOR ISSUE,…The Intermitant Rough Scraping Sound I Was Hearing Convinced me…( So I Thought ),…That It was A Hub Motor Issue !….So, For 2 Years I thought That I Would Eventually have it Looked at By The Closest Dealer 50 Miles away. Well, Last Month I Finally Popped out the Brake Pads & After Seeing they were worn out,…i Replaced them. PROBLEM SOLVED,…That Scraping Noise was from Worn out BRAKE PADS & NOT The MOTOR !!!
