The average cost of electricity in Prague in July 2022 was 52.15 euro cents per kilowatt-hour at the Czech Republic's purchasing power parity, making it the most expensive electricity in Europe.
In Prague, Czech Republic, a beer costs approximately US$1.60. The cost of the same size beer in other global cities like Oslo, Norway (US$10.30), Singapore (US$8.30), and Hong Kong (US$8.90) is considerably higher.
As far as I know, the NCM Prague comes with 36V controller. It's also 7A nominal, 15A max, which is pretty weak. Sorry I see what you mean by changing the controller, I was calling the display on the handlebar the controller which is not the case.... This thread must be so confusing right now haha
