The shipping was super speedy 5 stars, the technically of product itself is not good. Too many things to consider as problematic issues. Frame design of bike doesn’t always fit with bracket, motor free wheel and hub sprocket has no adjustment to make align, I ended up bought a new bike that fit the bracket and re fabricate things to make align.until now, bike is still not running .. too much to deal with
good service...but dhly charge me 59 dollar's...why I don't know.so I m little bit upset to this deal.
