My power bars did increase back to 100% sometimes. I also watched the voltage. Sometimes the voltage increase can be attributed to less load. I have a meter on my golf cart and I know how it regens on the same hills. It definitely does regen. You can sense a slight drag on deceleration...
I-PAS is the regen feature. IMHO the Plus model only provides a different display, more working modes, and shows the regen rate. It also provides more output to the motor. The extra output of the motor was the only thing I considered but decided against needing the extra power. I almost ordered...
Pick a bike that fits your mission. I have hills to climb and wanted full suspension for comfort. I also wanted to pick a folded bike to take along in my RV once in awhile.
I chose the Fat Bear. I chose it over the Rad Mini and a couple of other folding bikes because I also like the stealth...
I never use the throttle. On PAS3 and in 8th gear, I could easily maintain 25 mph while pedaling along casually. Some of my hills require me to drop all the way to 1st gear so I experience the full range of power. I was concerned that the hub drive is not geared but it is working out fine.
Simple - get out your credit card and order it! Do you insist on calling Amazon or EBay when you buy stuff? I think not. I ordered one because it is about the same cost as a conversion kit for the WHOLE BIKE. The risk is low. I am very happy with mine.
I received mine on Saturday. I unpacked it and took a quick night ride to make sure everything was working. On Sunday, I took it out for 17 miles of very hilly streets around my house. I can't wait to fold it up and take on our next RV trip.
It is am awesome bike for MY MISSION. I ran it on PAS...
