Sorry for the delay. As I mentioned in my previous post, I ended up flashing the 52V firmware onto the controller. It's not easy, you need to get a programmer for the microcontroller, download stuff and do a bit of soldering and guesswork. If you've never done any electronics before, this is...

Hi Sa444, I was having a somewhat similar issue, and my problem was that my battery was 52V, with a 48V motor, so the voltage was too high for the motor controller when fully charged. Here's how I fixed it...

As an update for anyone else having a similar issue, it turns out that my problem was that my motor was 48V, and my battery 52V. Somehow I had read somewhere that they would work together, but that was probably when using the OpenSource firmware. They don't with the stock firmware, apparently...

The chain isn't actually jumping. I initially thought so as well, but it doesn't. It's the motor that "jumps". My first reaction was that it looks as if a clutch was catching inside when that happens, and having read about the blue gear issues, I thought this might be it...

Thanks for your reply, Nealh! Are there some simple checks I could do to help narrow down what the issue is? If it's a controller issue, I imagine maybe a voltage is not what it should be, or something similar.

Hi everyone, I'm new here. I have been reading a few posts a few months back, and decided to get a TSDZ2 to fit on my commuter bike. It took forever to arrive and install with Covid, but I finally did a first 10 minute ride around the neighbourhood. The speed sensor was a bit hit and miss, but...
