tbrooks123, thanks for the observations. The new RadRover6 definitely requires more PAS. and uses more battery power than the RadRover5. Hopefully that'll change as the new tires wear in, and the bike loosens up a little. I only use PAS 1 and 2, and used to be able to go 20 to 22 miles before dropping to 80% battery remaining. Now, the RadRover6 drops to about 70% on the exact same ride.
