I begin to notice the voltage drop after about 8 miles and have to throttle back to stop the controller unit cutting out. Its enough to get me to and from work on one charge though. I can get up to 30mph on my bike but I stay slower just out of concern for pedestrians. I always slow down to a crawl when passing people, especially those who are walking dogs just to be on the safe side. Sadly there are those who insist on bombing down the footpath at full throttle who spoil it for the rest of us.
