Includes a 750W limiter wire when connected results in a casual steady speed using the PAS. Without it @1000W, it's dangerously fast, but handy. I put a switch on the limiter wire so I can toggle between the 2 choices. Because I was a newbie just buying into the e-world, I did not know of how limiting it would be with only 2 choices. Yes, I could upgrade to a SW900 LCD system but I'm gonna stick with what I was led to buy and enjoy the 2 choices I have! Hey, it's an e-bike for a fraction of the cost and biking will never be the same!
