I missed this in my last response. It's power based now, NOT speed. Speed is affected because of a change in power, but the settings are based on power. So, if I set mine to 5%, it will output a little over 30 watts, and it doesn't matter if I'm going up a hill at 5 mph or down a hill at 25 mph, it's still going to be a little over 30 watts because the setting is based on power, not speed. The bike will cut back power if you hit 28 mph due to class 3 regs.Doesn’t the current version of ride1up 700 give you control and allow you to edit/change the speed/power for each PAS?
