Once again the gang at eWheels have delivered by providing great customer service and blazing fast shipping of my new KS16-X one wheel. Seamless transaction from start to finish. Been riding outdoors for about two weeks now and I must say that as a beginner-rider, this wheel is perfect in that its very stable, durable, smart, and has plenty of power to spare for later when I become more of an intermediate, and eventually well-seasoned rider. I can't imagine out-growing this wheel any time soon! Great choice on a great recommendation by eWheels website. I highly recommend!!
