Canadian RadCity 5 Plus

[ChrisB]

I purchased 2 RadCity 5 Plus models last fall here up in Canada. I received one of them a week ago and the first thing I did was go into the advance settings and adjusted the top speed to 40 Kph. I knew that here in the land of the over taxed and over regulated, the wattage limit is 500. I just didn't believe that Rad would have a different controller or motor specifically for our small market. Well the options available to me are 250w and 500w in the advanced setting and I have no idea about the motor. Does anyone know what motor is in the RadCity plus models, and is a upgrade controller available for this new model?
