  • Great Value, even better bike!!! Super happy customer!!
I am fairly active and have been looking after my health and physical condition the largest part of my life. I try to get my exercise outdoors but living in NE Ohio weather can interupt the best laid plans. I have a treadmill to get my 3 mile walks in. A rowing machine some weights and TRX straps. Good all round stuff for home. Now, at 73 yo, I am starting to have foot issues so my Dr. recommended a stationary bike for a low impact on my feet but great for cardio. So research began at the top with peloton schwinn and others. While those bikes are great I decided that the classes and everything that came with them were not for me. So I started looking bare bones at Walmart Target etc.. A young store clerk at Dicks helped me and offered what features to look for on a bike. They said to make sure its comfortable and easy to ride. It needs to be adjustable size wise and effort (resistance) wise. They also said some are quieter than others, magnetic vs friction. After getting educated about what's important on a bike I started to look on Amazon. They seem to have the best selection and prices are all over the place. I decided that what I wanted was one with magnetic resistance for quiet riding, a flywheel that weight 30+lbs, 4 way (up down forward backward) adjustable seat and handlebars, and a way of measuring how fast and how far you might have gone. There are a ton of choices that have those features. I ran across Sunny Health and Fitness. I researched the company, liked what I saw in their catalog of products and decided to go with something from them. I decided on this bike SF-B121021. It checked all my boxes and has a great price as well! It was on my doorstep in 4 days. The box was somewhat damaged by the shipping company but the product is absolutely fine. I put it together in 40 minutes no problem. They include the tools you need so don't fret that part. I took my time to set it to fit me. The seat is ok for me right now but I might try to find a better seat later, not a big deal. As for my riding experience it is incredibly smooth and quiet. I can easily turn the resistance up or down as I ride. There is no read out or marking for resistance you just remember the number of turns of the knob. The workout I get on this bike is incredible. Really different feeling after a half hour on the bike vs the treadmill. I'm loving the different muscle groups each uses and giving my feet a day or two off. This is a great purchase and I'm very happy. I'll update if something significant occurs ... show more

  • almost perfect, pulse monitor?
This is a quality machine. It was fairly easy to assemble. It is silent in operation and offers as much resistance as I could want. The seat is comfortable and looks durable. The seat and handlebar adjustment work well although I did have to raise the handle bars higher than the range scale would indicate, I just like to sit more upright than what must be considered normal. It can be moved around on the wheels fairly easily, at least on a hard floor. My only serious complaint is that the pulse monitor just does not work. It gives a reading but not one even close to accurate. I am baffled by this failure as the technology to implement an accurate pulse monitor is fairly well known and available. I frequent two health clubs and most of the machines have pulse monitors and they all give me accurate readings. Why a company like Sunny could not implement one is a mystery to me. Fortunately I have my own chest strap type pulse monitor as well as an optical type so this was not a big issue for me. Having a pulse monitor that is inaccurate is worse than having none at all, although the one on this bike is so inaccurate I doubt anyone takes it seriously. They should have left it off and lowered the price $20. ... show more

  • Love it!
Assembly is a two person job but the steps were easy to follow and execute. The bike is solid and so quiet. It is easily adjustable which is great as we both use it regularly.

Similar quality to what you’d find at cycle bar - incredible value for the price. Would definitely buy again.

  • so far so good
Product arrived a few days ago and I rode it 3 times so far. Everything's pretty solid and it's a quiet ride. -1 star because the part where the main frame attaches to the stabilizer bar (front), was damaged (slightly bent) during shipping. Recommend manufacturer to use tougher shipping foam for that area to prevent damage during shipping. Other than that, good value and seems well-built. Will update in 6 months. ... show more
