This scenario has not been an issue for me. The system is not only looking at your pedal cadence. I believe it is also looking at vehicle speed and takes both into account when determining the correct gear ratio. No disrespect, but people who think they know how it performs that have not had the opportunity to try one should spend some time with one before saying what it can and can’t do. I live in a relatively hilly area and it performs incredibly well. Starting, stopping, ascending, descending, accelerating, decelerating…..it really does just work. Is it perfect in every scenario? Probably not, but it’s pretty darn good! Try one before writing off what it can and can’t do.I realize that an automatic probably can do this downshifting, but I also want to be ready to resume my pedaling cadence if the opportunity to go should happen before a complete stop.
Now, if you like to adjust your cadence throughout your ride versus maintaining a fixed cadence, then a manual option probably makes more sense.
