Thanks for the feedback Kurt. 60 km range should be plenty as my new commute is only 15 km return. The top speed will not be ideal, but given most of our rural roads are pretty quiet and frequently contain bicycles, I can get away with 80 kmh.
The breakdown of the trips speed limits is 2km of gravel at 60. 3 km of rural highway at 100 kmh and 2.5 of town at 60, so shouldn't be too big a problem.
Was hoping to find out if anyone has used these before and if they are practical, or if they are a toy that may disappoint. This is also the reason I looked at the demo ones. At $2000 if they are useless it can live in the back of the shed and I have not lost a fortune
