Good news. I took the Stromer ST2 that had been adjusted with the iPhone app to maximize agility and that almost completely eliminated the pulsing. I say almost because when on a flat road at top speed I could still feel it, but not to any degree that annoyed me. When going up an incline I could not detect it at all. I've attached the screen of the app where these settings are.
Note you can also set the top speed and the torque both of which I set to maximum. These settings affect Mode 2 and consequently its not longer as eco friendly.
But the most important things are:
- There definitely is a problem with pulsing in mode 3 of the Stromer St2.
- Not everyone believes its a problem (see the poll) results so far.
- Stromer considers this pulsing "normal" behavior.
- You can almost completely eliminate it with the iPhone app settings.
- I have no clue why Stromer makes fixing this so obscure or why even dealers are not aware of it.
I'm buying this eBike!
Thanks for everyone's participation. I hope you all learned something from it.
