Hello there!
I have been the happy owner of a koga miyata ebike for the last few years. I had a mishap climbing a local hill in a high gear and bike is now unusable.
Symptoms:
there was a cracking noise and now the rear sprocket is no longer connected to the hub - it just spins uselessly.
I have taken the wheel off the bike. Not sure what the next step is? I have removed the six torq screws holding the plate on the hub but was unable to remove.
Can someone help me diagnose the problem - the bike is out of guarantee so I would fix it myself if I knew how - assuming no special tools are required. I looked at a tear down video on youtube of another hub and the mechanic had to use a three pronged auto tool to remove the hub - I am not sure this is even necessary in my case - maybe I just need to replace the sprocket.
Be glad for any tips,
Graham
