For those with BBS02/SHD Error 21..

Hello,

My BBSHD failed after two months of using it. Got Error 21 in the display and PAS stopped working. Running the motor with the throttle worked though and the speedo was correctly showing actual speed. I replaced the speed sensor on the wheel but no change.

Finally after having enough of it, I opened the motor casing out and find my fried speed sensor. It failed due to shortening out, power/ground wires came loose due to poor soldering. Now replaced and should hopefully work as intended.

Thanks for reporting. This is not an isolated incidence. I bought mine from Luna and it has always been like this. I have to open it up and fix it.

Your report of the specific issue leads me to believe a simple solder fix will do.
