Programming Controller

[Emmanuel27220]

I think I have exactly the same problem as you. I own two bikes. One with a Bafang 750-watt motor and a KT-25 controller, and the other with a Bafang 250-watt motor and a KT-12 controller. The pedal sensor is not KT branded for these 2 bikes. When I pedal at maximum speed, there are very regular micro cuts, just like you, I think. I ordered 2 KT pedal sensors, we'll see if it works. In the meantime, have you managed to solve your problem CamelP ?

And also when I decrease the value of c5, there are fewer interruptions, but there isn't much power left.

I myself did not want PAS because my ebike PAS kicked in hard taking me to about 15 km/h . In slippery conditions you need 6 Km/h or slower sometimes.
I have a 1/2 twist grip throttle which allows me a good grip and good throttle control so I can have it help me without a surge of power.
My PAS would cause me to spin out so I disconnected it .
I always have the throttle ready when going up hill or through sand or snow . I find it is much safer now.
It's become natural to add throttle when needed . No more surge of power .

Hello,

I've run into an issue after installing my new display, specifically KT-LCD8HU.

While my bike is trying to maintain / not go over the top speed, the motor will consistently cut in and out every other second or so, which I think is pretty normal except you can physically feel it to the point where it makes the riding experience incredibly unpleasent, this wasn't an issue with my old KT-LCD8S display, unfortunately I am unable to see which settings my old display has so I can't directly copy them.

I'm hoping someone here has an idea how to make the riding experience more pleasent / smooth.

Bike specs:
Bafang RM G060 500 D
KT48ZWSRD-BSKI2L, 20A controller
Tyre size: 20x4.0
Gear reduction ratio: 5:1
Magnetic poles: 6

The pattern reminds me of times when services kept restarting because limits or thresholds weren’t aligned after an update. Digging into DevOps practices helped me understand how small setup differences can create those annoying on-off cycles. Reading material from https://neklo.com/devops-services gave me a clearer picture of how to keep configs consistent after swapping components. Once I started applying that mindset, troubleshooting became way smoother and way less frustrating.

Sounds like a tuning mismatch between the new LCD and your controller

Another update, while I'm pedalling if I start using the throttle, the stutter will stop and the bike will maintain full speed smoothly.

This is because an active throttle overrides PAS input.
