Shifting the cassettes ARE NOT smooth

[dondelinger]

I installed the kit last night (it was dark and rainy) waiting for dawn to ride the bike for the first ride. I started up the mountain and I could feel the power right away. Wonderful. However, when I shift to the next gear, there is/was a pause, like the system brakes me for just a moment, maybe a full second. It's enough to know there is something wrong. I figure it's something wrong with the gear sensor. But how could I fix it? Is it some way to adjust it?

The gear sensor works by stopping the motor while the shift happens. It can last a bit longer than the actual shift duration. This prevents damage, but you will feel the power turn off, then on. Normal.

Is the duration of motor time out during shift settable or programmable?

I think the correct answer is, no, not directly - that Bafang has not exposed the time-out value/variable. Fortunately the sensor works well in most cases. It can be fooled by a shift butter-finger, indecision, etc.

It's not programmable, but I think it adapts to how fast the bike shifts. When I do a slow shift, on purpose or due to cold/thick cable lube, the shift sensor seems to wait for the cable to stop moving, then still pause briefly before re-applying power. I think it senses motion and waits for that to stop before re-engaging, as opposed to just starting the timer when the cable starts to move.

I have lubed my sensor at the pulley pivot, and roughed up the outer edge of the pulley, so it moves exactly as the cable does; doing this did make the timing seem more consistent.
