I found this forum while searching for info, parts and solutions for my Haibike MTB.
I am still searching for a good US source for parts, Haibike and Yamaha e-bike PW-ST System.
Thank you in advance for any useful info...
Hi, does anyone know what the error code 73 means on a Yamaha PW - ST motor with the Yamaha display A. It powers on for a few seconds with the display code, then goes off. Thanks.
