e222b City Commuter questions

I just picked up a 'city commuter'. I think it is the e222b.

First question - it appears to only have 1 PAS level that shouts off around 13 mph. Any way to upgrade to the 20 mph that other models can reach

2nd question - it appears to be pre-wired for rear and front lights. I tried connecting a 5 pin rear light from my other bike. I turned on the bike and it didn't light up. I squeezed the brakes and nother :-(. Wondering if anyone has utilized the pre-wired connections with success.

3rd question - do these models work with the GenZe app. It communicates with bluetooth.
