I've had my Mobo shift about 7 months. It's fantastic. I have spinal stenosis and had to give up my regular bike. Found you on line, looked it over and ordered. It wasn't to hard to put together. The instructions could have been a little clearer. When I went to YouTube and watched the video, some of the instructions there were different than the ones that came with the bike. It was a bit confusing. Beyond that, I ride it almost every day. I'm on my second set of rear tires. I was able to convert to street tires by getting them at the local bike shop. My longest ride has been 7 miles. I have no problems going up small hills or inclines like bridges. It's nice to be able to pull over in a nice area and just sit and watch nature. When I have had any problems, I always good quick and good help from you people. One time the return call was a little late, a week, The man who called couldn't apologize enough for not getting back. I am always satisfied when I need and get assistance for my bike. It's winter here at the moment, so my bike is in the garage. I'm looking forward to another season of riding my Mobo shift. I will buy another one when this one goes. Be sure of that.
