Aventon Pace 350 Step-Through Error Code 21

[mrchu39]

I just recently bought this electric bike (like a week ago) and only a few miles in it is already displaying this error code, which according to the manual is a current problem. I tried their troubleshooting and ensuring the cables to the rear wheel are attached properly, and it is still giving me this error.

Hi there, Did you end up fixing the problem with your Aventon Pace 350?

Error 21 means something is wrong with the cable that connects the rear hub motor to the system.

Current Error

HOW TO RESOLVE
Check the cable that connects the rear hub motor to the rest of the system. Make sure it is free from grit or contaminants and is firmly connected.
