Running the Rad at 24.7 mph all the time is like driving your SUV at 125 mph all the time. The Rad can do it; but, it going to wear out the e-parts a lot faster compared to 15-20 mph sweet spot. My average speed is between 16-19 mph work commuting with 500 foot elevation change from home to work. I have my LCD screen set to 36 km/h, wheel size 28", and tire set to 21-23 PSI on my Vee8 120 tpi tires. I also upgraded my brakes to TRP Spyke and Jagwire brake cables to help shorten my emergency braking distance at +20 mph. It takes a lot to stop me at +270lbs at that speed.
I have two 2016 Radrovers with +5500 miles between them.
