I finished up the mother's day / birthday flower garden for my wife today. I was pretty much worn out by the time I had the garden completed. I rested up some and then decided I would ride. It was very windy but oh well. I headed South and my back was hurting. When I started to battle the South wind it really was bothering me. I decided that when I got back home I would just call it a day. I was just departing the town South when the assist became all but non responsive. Instead of cutting out now and then, the motor would assist now and then. I had the wind on my back and found that the throttle still worked. I stopped and unplugged the sensor cable and then plugged it back in which gained me nothing. I got home and came in and pouted for an hour. I then went out, turned the bike over, and changed the washers adding a fraction more distance between the number nine gear ring and the sensor. Flipped the bike back over on it's wheels and rode across three blocks, down to blocks, across the three blocks, and back home without a single cut out. I came in, changed back into my bike clothes, and took off. I rode around the block and back home. I had zero assist. I'm sorry.. I'm mad as hell. I can't fix something that is that fickle. What made it work.. and what made it stop working again? I simply do not get it. My wife said flip the bike over and back again and see if it's fixed again. I laughed but she might be right...
I looked back through this thread. It proves to be a great source and timeline. I read that the controller, like every darn bit of an e-bike, is not expected to last as long as it has on the bike. I took the upgrade controller I put on the bike when it was new off of the bike and put the original back on in hopes it would fix the problem 200 miles after the new sensor install. It fixed nothing so I put the upgraded controller back in the bike. I plan to put the original controller back in the bike tomorrow. The test will cost nothing and I can do it now. I will search for a new sensor as well.
$200 sensor
$150 motor
$200 drivetrain
$550 towards a new bike and the more I spend the worse it seems.
