Satisfactory? Really? 5 months later, i,m waiting for a refund. I had to borrow $500 to order another battery. I may be mobile by August, if I,m lucky. All my plans are ruined, I have missed everything. I,m in the same place as I was in Feb, only in debt, with 2/3 as much battery, and nowhere to go. I have a brain injury, i can,t just head out on my own. I need specific destinations, and people I know at them. Took all winter to arrange, not gonna happen this year. I,m 125lbs, and exhausted, can,t focus, and forget what I,m doing every couple mins. It took me 3 days to replace hall sensors, and phase wires, maybe a 2 hour job? Now I have to build a new battery compartment, rewire, reengineer the bike etc. I was going to run 2 motors at 48v, with one CA. Now I have to run one motor on 36v, meaning different gearing, wiring, throttles, another CA?, controller programing, etc. More than I am likely to accomplish. More like a winters work. So no, I don,t find it satisfactory, and I probably won,t be moving on for a while, though your comments are certainly the way I would chose to go, were it not for my messedup noggin. I simply have nothing else, and have thought of nothing else, because it,s the only way I can accomplish anything. I did it all winter, it,s a full time job, and very tiring. I don,t eat, sleep well, etc. And end up in bed, or the hospital where I spent 6 weeks in march/april. I haven,t gained a lb since, and am simply too weak to jump into that state. Perhaps understanding what it takes for me to accomplish what would once have been a couple weekends project, will allow you to understand my difficulty dealing with it. I used to build motorcycles from scratch, frames, bodywork, everything. Now a bicycle is really too much, sucks.
