My wife and I both purchased a City Commuter 48V bike a little over a year ago. The area that we live in has a lot of mountains and trying to get home after a long bike ride was no longer fun. With these new bikes we can ride until we are tired and still enjoy the ride home. We recently got new batteries in the recall but my wife's battery was DOA. I called support and was helped by Casey. He had me run a few tests on the battery and then walked me through fixing it. Casey was everything CUSTOMER SERVICE is supposed to be.
