I got the SW900 LCD display. PAS works. Throttle works. I played with it maybe 30 minutes total.
Out of the box, SW900 in defaults (I guess), it was way quicker than I expected.
By that, I mean with very little effort pedaling, the bike kinda "took off".
It wanted to go faster than I could reasonably pedal on the 14-t gear. I need the 11-t.
The speed mode was in Km/hr by default, I later toggled it to M/hr, but reported speed was still too high, I think.
I hope to learn how to fine-tune the PAS behavior by adjusting some SW900 parameters.
I'll double-check with Ebikeling for the SW900 defaults for my setup.
They've been responsive & helpful to me so far.
Can someone point me to the forum topic on the SW900 that explains in detail each of the variable parameters?
