I'm at 20 miles now and the bike is growing on me. The PAS mode has more power than the thumb throttle does. Since my main purpose for this bike was for health reasons I may be removing the thumb throttle once I have the bike setup for me to pedal more comfortably. Today my rear rack should be here. I intend to secure a spare battery to the rack and run the first battery dry to get my range dialed in. I already removed that thing they had attached to the seat post where a seat usually is mounted. I think it was some sort of mid evil torture device. I wander if I can get a 72v controller and run these batteries in series for a bit more speed.
