Awesome spin bike! Works just as good as the bikes at my gym. The seat will take few weeks to get use to before it will feel comfortable but thats the same with all bikes I’ve tried. Super easy to assemble but it does take two people. I ride along to online classes and its been so much fun!

I purchased this one to replace an old Schwinn spin bike that died on me, had it for 10 years. This bike is great! I’ve had it for a few weeks now and no issues. So far I have put in at least 400 miles. What I like the most is that there are no cheap electronics on this one, or any electronics at all. For me those are useless. I installed an Garmin speed and cadence sensor to track my speed and distance and paired it with my Garmin cycling computer and HR strap, I get all the stats I need to help me improve my cycling. Just set your computer to virtual cycling before the workout and you are set. As an added bonus, you can update your workout to Strava and track your progress.
The fly wheel is heavy, which is great!
If you need to have a Peloton style workout there are plenty of free spin videos in YouTube that will be just as good as a subscription service.
My only recommendation would be to not use the included saddle as it is trash and spend an extra bit of cash to get yourself a good quality one. It make all the difference.
Assembly was easy and instructions clear.
Quality is just as good as those in my local gym. My only warning is that this bike is geared towards taller people. I am 5’11” and the fit is perfect. So far I am extremely happy with this one.

EDIT 6 Weeks in: You NEED a bottle of WD-40 with this bike! I have been using it for 45mins-1 hour almost everyday and it has kept up well with the intensity of my use. However, when “out of the saddle”, the crank arms/Axel developed a terrible squeaking sound that just got louder with time… the application of WD-40 just cleared the whole thing up! So far, that bottle has fixed every problem that has come up on the bike, from squeaks, to dried out break pads, to a finicky resistance knob. It’s great!
I bought this bike in the doldrums of quarantine for my home. I take Flywheel classes quite frequently during normal times, so this was a good way to get connected to my favorite instructors who are teaching on Zoom and also use the Peloton app to supplement.
This bike is very easy to setup; it took my dad and I about half an hour. The other pedals I had ordered (I prefer LOOK Delta, so I had to bite the bullet and order Peloton shoes and pedals) hadn’t arrived when the bike did, so we installed the toe cage-pedals and I used those for a week until the other ones arrived. A word of caution is that many people have said the crank arm fixture where the pedals get screwed in can have its threading stripped quite quickly, so definitely read the directions and use a wrench only to tighten.
The resistance is not the smoothest, but there is a sliding scale of light to heavy and you will get used to the amount you should turn the knob the more you ride. For me, I was able to correspond the numbers I’ve heard called out innumerable times in class to what I felt, and it is working quite well.
The bike itself is sturdy. On the belt-drive version which I have, the belt is covered by a plastic-type cover- not the sturdiest, but it doesn’t take any heavy pressure, so no harm, I guess. With regards to the seat, it really is a matter of comfort. If you are used to studio-style spin classes, odds are this seat is in line with what you have historically used. Something to note is that I am about 5’10” and I am using the maximum settings on the seat and handlebars, so I don’t think someone much taller than me is going to be ultra-comfortable on the bike.
For someone used to all the technology of Flywheel, this bike was a little bare-bones but provides the latitude to add features at your discretion. The handlebars are good for a tablet holder which can be used to stream whatever class you are tuning into. The Wahoo cadence sensor is a very nice touch that can be linked to numerous apps and will tell you the all-important RPM number. It’s super easy to setup. The pedals are interchangeable with standard 9/16″ pedals, and some type of specialized spin/bike shoes are the way to go for peak performance. I will say that LOOK Deltas have a wider surface area of contact and better power transfer than SPDs, but it is really personal preference.
I took off a star for noise because the bike isn’t ever free from noises here and there even when you lubricate the brake pads with the recommended WD-40 silicone spray. The belt drive definitely helps to keep things down, and if you are using headphones for music or the class you’re taking, the noise isn’t noticeable.

My Sunny Health & Fitness SF-B901B Belt Drive arrived on time and in excellent condition. They have done a fantastic job of packaging a large and heavy item. The assembly took less than a half hour and had very good quality tools to complete the process.
The bike itself is very sturdy and has a smooth and quiet ride. As many people say the seat is a bit uncomfortable at first but after a few weeks I found that I had gotten used to it. The price point is very good and well worth the money. Do not expect any bells and whistles such as heart and calorie monitors but there is less to go wrong. I highly recommend this product.

Looking for a bike of this type I never considered Sunny until I started seeing the reviews on them. I was skeptical of the quality for that price. I also called the Sunny company directly several times for info and questions I had, and was impressed in their product knowledge, courteousness, and it was nice when calling them to just get a live person immediately who could answer the questions. Once deciding on Sunny, I had to decide on which model, and through much reading, comparing, and phone calls I went with the SF-B901B, and it turned out to be a wise move. For home use it is perfect for my needs. I can’t really compare it to any other name brands because I haven’t tried any others, but I will say it provides the workout I was expecting and much more. I got the Belt version, as opposed to the chain, and it is very quiet. The bike seems rock solid and doesn’t move in any way when using it. The brake works perfectly, which is very important. The bike arrived much sooner than originally estimated, and comes in a single box, and is heavy. If you are going to use it on an upper floor of your house, like I do, I’d suggest opening and removing from the box in the garage; it is then much easier to carry the bike up by itself before attaching any of the components. Less messy too. It took about twice as long just getting the bike out of all the packaging as it took to assemble. The packaging seemed a pain to get everything out, but worth it since the bike arrived in perfect condition. Most of the bike comes assembled, you just need to attach the base, install the pedals, handle bars, and seat. Took about 15 minutes and it was ready to go. The seat is not the most comfortable and I will probably replace that later, but no biggie, the bike works great and seems solid. One thing it doesn’t come with is a monitor for time, speed, heart rate, etc. which I knew before purchasing, and for now at least that’s ok. It gives a great workout, rides very smooth, is quiet, and despite being heavy, little over 100 pounds, it is easy to move using the front wheels there for that purpose.

Amazon Customer –
El producto es muy bueno, de gran calidad, se ve y siente muy resistente y firme. Puedo pedalear de pie sin preocuparme.
Yo mido 1.81 y peso 91kg, y en todo momento me siento seguro al pedalear.
Pros:
Muy cuena calidad, resistente, y firme.
El precio, lo consegui en una superoferta, $6,999.00, eso sÃ, espere como 6 meses.
Contras:
El asiento es duro, supuestamente es bueno que sea asi, pero no se me hace comodo.
Los pedales tienen una parte para colocar el pie. A mi se me hace incomoda y no la uso. Soy talla 30 en México.
Otras observaciones:
El producto es pesado, y un poco complicado de subir a un tercer nivel.
El armado es relativamente sencillo, tuvo complicaciones pero nada que no se pueda solucionar. Tarde 40 min.
No conozco otros productos, pero me hubiese gustado que el sistema de la banda, fuese como una bicleta, que cuando no pedaleas, la bici sigue moviendose y los pedales no se mueven.
Recomiendo mucho el producto.
