Contact CS for a basic question Contact CS for a basic question. CS tells me to send proof of purchase and bike serial nmbr. It has no serial nmbr. I wish I would have purchased elsewhere. Their assembly instructns are not complete. If you have not built one before this can cause severe damage. Can cause damage that may not be noticeable immediately. Those who do talk there try to blame problem on it being Chinese made. They are not nice or helpful people. Also beware of spiders coming out of box. Their CS answering system is only a run around of wasting time.

Easy to assemble, great to use I'm 5 feet tall, 65 and female but put my step trainer together easily and quickly by myself! I broke both my ankles and one fibular a year ago and needed a smooth exerciser to strengthen my ankles and for cardio exercise. The stepper is just the thing and shows all the details you need throughout your workout. I highly recommend this exerciser

Nice smoith ride and goid fit… I purchased the SF-B12021 exercise bike after listening to several reviews on similar models. I chose this bike after a lengthy conversation with Ursula a customer representative at SF. She sent me additional information and after review I purchased and it was atbmy door steps less than a week later. The bike is smooth ride, study and well made. The many adjustments makes it a good fit for anyone. The assembly was easy but bike is heavy. The packaging was good and secure. All components were available with tools for assembly. My first ride was like wow. For much less than the big box bikes I can still sit my tablet on handle bars and ride in any fitness classes. Thanks again Ursula Tony

Great Customer Service The bike we purchased is wonderful. When we received it the seat was torn. We contacted customer service and they immediately sent us a new seat.

Bad product, worse support Blown away by this company's low quality treadmill and lackluster customer service. The treadmill I bought stopped running and while in communication with Sunny I learned that the issue actually originated from it being misaligned from the get go. The customer service tech had me jumping through all sorts of hoops to "fix" it, none of which addressed the issue at all, and in the end completely failed to stand by their product. Sunny's bottom line was basically the corporate version of "sucks to be you, maybe the retailer will care." Outside of a shady used car lotz I've never seen anything like it.
