Mostly pleased with the 4 whopping miles I’ve put on it

(It’s too hot here to ride!)
I had it on settings zero-through-five for pedal assist, and didn’t realize it - I thought it came 1-3. So I was getting it up to level 3 in "normal" mode, and it was kind of slow… And eventually I realized I had two more levels past that and - once I kicked it up into PAS 4 and 5... wow, this thing really took off! I just took it out and throttle-only with soft tires I was doing 26.2 mph indicated on the controller, but I haven’t clocked it against a car or speedtrap radar, gps, etc.
Setting differences I see immediately:
Your wheel is at 20" mine is 24".
Your Assistant Num is 24, mine is 12.
Your Power Set is 0-7, mine is 0-5.
Your Slow Start is 0, mine is 3.
I honestly don't know what "Assistant Num" is. Does that mean yours is set to provide twice as much power to each manual pedal?
I don't know if the wheel size is affecting my speedometer reading enough to explain a 6 mph difference. I'll take it out later and keep pace with a car with a known speedometer. I just "poor man calibrated" my Honda CRV against a police radar sign, and it was pretty spot-on reading the same speedo vs. radar sign when at 25 mph.
Uphills it seems to be pulling fine, and the assist doesn’t kick in too clunky or anything. Settings 1 and 2 are mild assistance, but then 3 & 4 it's like bionic legs.
Down sides/problems: Obviously like with all ebikes the whole "not pedaling around corners" has been a weird thing to get used to for me. One thing that's a negative that I’ve definitely noticed on this bike is the frame is so wide in the back that I’m hitting my heels on the frame when my pedals are to the rear. Maybe I’ll put on bigger pedals or just try to remember to place my feet forward on the pedals so my heels don’t hit the frame. My Wife has a Lectric 2.0 on order it’ll be interesting when that gets here to see if that skinnier frame has the same problems or not.
The packing was fine, but there's a little of the spray foam stuck to the handlebar adjustment area. No big deal, but I'd seen horror stories of people that had tons of foam stuck to their bikes... this was easy enough but took ten minutes to get most of it off.
The last notable negative is that my rear rack was delivered crooked as a congressman, and is WAY off center. The brake light is easily three inches off center and the whole rack "leans" to one side... I wrote Yamee and they advised it was probably dented in shipping and to "hit it with a rubber hammer" which I haven't done yet. It may be miswelded, it may be exactly as they say and whacking it IS the appropriate solution, but... seemed a little ghetto reply. Fast email response though. Shrug.
Display is too bright for nighttime preferences - I mean, it's blindingly "good" but I had to turn it down so it doesn't wash out my road vision. Other than that, I didn't change settings much at all. Just confirmed the 0-5 PAS setting - didn't mess with percentages, turned cruise control off because I don't want that kicking in during the learning curve time, left regen on, been playing around with different heights of bars and such.
