I bought the usb cable from Golden motor Canada and used the version 4.0.0 of the Lingbo software.
I’ve been able to reprogram the controller and now full throttle on the bike stand I get 110kph
Here's a link to the file and two short video of the speedo

If you want I can post screen shot of the settings.
My next upgrade is to be able to recharge on any level 2 public charger.
I bought the J1772 plug socket and a 240V 12A charger.
When this is done I'll try to increase range with a bigger battery or have a second one in parallel like you want to do
