I ordered a Kingsong 16XS from eWheels about a year ago. It has been the most fun I've had in a long time! (59 y/o) I've put on 1925 miles in that time, riding to work and back, trails, streets (low traffic), and even down to 35 °F in winter. eWheels got my machine to me speedy quick and I have had absolutely no problems with it! I've been wanting to ride for longer distances with other riders, but didn't have a fast charger to keep up with others. I ordered one from eWheels and they had it to me in record time! Like my wheel, absolutely no problems! I can't say enough good things about eWheels. Worth your time to buy from them!
