The new one has other improvement: brake pads are now bigger rectangular shape, instead of old circle shape. I think the old one is more for scooters. Though I don't feel any noticeable difference. I ride on flat roads so even the old one worked fine.
Another change is that now level 1/2/3 also limit max speed for PAS mode. In the old version, levels only limit max speed for throttle and had no effect on PAS. E.g., I could be on level 1 and still pedal all the way to max ~20mph. Now I can't. Not a bad change — lower levels seem to consume battery slower (at the cost of lower speed) so if you are a few miles away from home and the battery shows empty bar, you can go down to level 2 to last longer (at a lower speed). Keep in mind this is a bike with cadence sensor, not torque (usually way more expensive), so the amount of help from motor is fixed (per level), and does not vary based on how hard you pedal.
One change I don't like is that they removed the voltage display. But they seem to have improved the accuracy of 5-bar gauge — old one jumped a lot between 1 and 4 bars when I go up hill. New one seems to fluctuate less drastically. I still want the old voltage display because I can control my charging pattern for battery health. Eg charge to 48-49v the night before. Then charge it to full right before I leave home next morning. (Your iPhone optimized charging works same way)
I ride it a few times a week to commute to work. 15 mi round trip. In summer it can handle round trip in one charge and still has 1-2 bars left. During winter the battery doesn't last as long (as expected) so I usually barely made it home with empty battery icon flashing. Now I bring charger into office and charge before going home.
Had about 700 mi on it (both old+new bikes combined). Generally happy. No major issues. Just need to adjust brake caliper centering a few times (happens to all bikes with disc).
Only complaint is that the motor helps me too much and makes me cold in winter riding as I'm not getting enough workout (but that's perfect for summer). That's how cadence sensor (instead of torque) works. Just wear more layers of clothes
If you want adjustable level of motor help so you can still workout a bit, get one with torque sensor, though they are usually a lot more expensive.

No, there's no such feature. No re-gen or pedal recharge.
Yes the new post recommended by an earlier SD thread works better for me, even if I'm only 150lb and 5-7 — I can pedal with legs more straight, and it doesn't sink as bad (still a little but not as bad as the old one). Do keep in mind that a higher post moves center of gravity higher, therefore reduces stability. There was once or twice when I started too quickly after red light turned green, my front wheel left the ground for a fraction of a second. I didn't fall but from that point on I lean forward and start slowly.
If you are concerned about sinking post, maybe you can buy the longer post and have it sits on bottom of frame so it will never sink -- assuming the post has enough length for your need. For me, I even cut the long post a bit (using a circular saw) so both me and my child can ride it without swapping post.
I patched the rear tire once when I hit a nail one day, but it didn't require me to take off the entire wheel — I just pull out a section of the inner tube, patch it, and put it back in, without taking off the wheel itself.
I haven't tried to take off the entire rear wheel but believe it's doable — otherwise how did they put it on. From quick visual inspection I didn't find a power line connector that most other e-bikes have, so that you can disconnect the cord and remove the wheel. But the cord seems long enough for the wheel to be taken off even without disconnect. Just my guess. No such need yet.
Front wheel should be super easy to take off completely.
Folding is not as handy as they advertised. It's heavy and bulky, and the carry handle is off from balance point (when folded) so you need to use the other arm to help. When you also fold down the head tube, be very careful not to let the LCD screen scratch the ground (rotate the handle bar a bit to protect the LCD).
With that said, I have no problem folding it and put it into my SUV trunk, even without folding the head tube. The pedals are sticking out a bit annoyingly, limiting my placement flexibility — I can make it work but have put it in in certain angle. Depending on your car too. Some SD users replaced the pedals with folded ones so that's an option.
For bus, it depends. If you practice a bit and have the strength to carry a 60+ lb thing with controlled movement thru narrow stairs / aisles, it might be OK.

~60lb
Yes. In newest version, level 1 limits at about 11-12mph, level 2 at 15, and level 3 about 20-21. This is for both pedal assist and throttle (older version only limited throttle)
