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

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

Wonderful customer support Wonderful customer support. My treadmill motor started making a loud grinding noise 8 days before the 6 month warranty expired. Sent an email to Sunny. Stephen responded that same day, asking me to send a short vid to verify my problem. Next morning, he replied, and said a new motor was being sent to me! It arrived 3 days later. Excellent company!!!

Lauren was excellent Lauren was excellent. She was very patient with me. The rower I got (sf-rw5515) is functional and cheap, which means its a good "starter machine" to see if you have the dedication and willpower to take up rowing. If you like rowing and can use this machine routinely for awhile, you can always upgrade for a better model later. The only flaw with the machine is that it doesnt count distance. It counts time, strokes, estimated calories burned, and total strokes over the machines life. But for like 200 dollars, its fine.

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.
