What I've found with the Ultra, it's much like the 4 stroke ATV/quads and dirt bikes I rode for so many years. At cruise speeds, you really don't need to change cadence or power settings much. You just change gears to adjust your speed! There's SO much torque available, the motor really doesn't care about the load you have on it (within reason).You have some valid points here. One of the things I like riding a quality hub on the road is shifting does not effect the output of the motor since the rpm of the hub only depends on speed. After the shift the hub resumes giving the same amount of power as before. That is probably what you also like.
When you shift on a mid drive, that results in a significant cadence change, this results in changing your point in the powerband significantly. If you lower your cadence too much then the motor, especially at higher support levels, will give less power until you reach a similar cadence again. That is probably what you feel. Of course at lower support levels or with big motors like ultra this effect is minimized. So the advantage of mid drive in climbing becomes a disadvantage when riding on the not too steep roads.
The delay that people experience in cheaper hub systems is a combination of having a low resolution cadence only sensor and low sampling rate at the controller. The lower the resolution the more angular movement it takes to detect speed hence will cause a delay. Also low quality controllers do not have the proper implementation that will create a smooth start for these motors. The forums is full of silly generalizations of these systems by looking at the low end systems.
Re: cadence resolution, that setting is ALL over the ball park depending on what bike you're on, and that's true on both mid drives and gear driven in my experience. The important difference is, whether or not it's adjustable to YOUR 'druthers.... For picking your way through a tight single track/low speed handling, I like it super sensitive, even if it cause me an accidental self start on occasion (shame on me!). Others, in an attempt to avoid something like an accidental self start, will go 1/2 turn on the crank or more. THAT's a delay!
Newest software settings on the newest Ultras cuts assist completely until the wheels are turning. No PAS OR throttle available from a standing stop! No using the throttle to get the bike moving! Right or wrong, people can make a case to support this. To me, that makes an awesome case for the ability to set it the way I prefer.... and thank God, that's possible on these new Ultras.
