Anthony Garcia –
I didn’t even know there were multiple versions on the Q20. They asked for serial number photos before shipping so I didn’t order the wrong one. Really appreciate that because returning packages is never fun.
James P. –
Finding a replacement front motor for my Q20 Pro was much harder than I expected. After providing the motor serial number, I finally understood which replacement I needed.
Robert Jenkins –
I was worried because there seem to be several motor versions with different connectors. Sent photos of my hub motor and they matched the correct replacement. Everything plugged in without issues.
