I did another long ride yesterday. I took the Aero and my wife rode her Flow. We did 23 miles. I had 2 bars left on the battery riding at PAS 1 and 2 and my wife had 4 bars left on her Flow riding at mostly 2 and using the throttle quite a bit on the in the last 6 miles or so. I enjoyed this ride quite a bit but I have a couple of cons:
1. The controller is kind of cheap feeling. It has a lag when a button is pressed causing me to overshoot the intended PAS level pretty often.
2. This is a personal preference thing but the Flow ride is more upright and the Aero ride is more aggressive. Because of that my upper body weight is resting on the handlebar grips. This caused a bit of discomfort on my palms. Maybe I'll get used to it or maybe I'll look for some upgraded grips.
