Before my in depth review, I just want to say that I love this bike. It is extremely sturdy, easy to assemble, and comfortable. The ride is very smooth and it is a great workout!!! I love the magnetic resistance. I've been on commerical bikes at gyms and boutique studios and these definitely compare. I ordered this bike and it started making a noise after only a few uses. I called sunny health and fitness and they were extremely helpful. They took the time to help figure out what the issue was and sent me replacement parts that came within a few days. We exchanged several emails and phone calls and they worked with me until the problem was resolved. They told me the bike was damaged in transit and sent me a replacement part right away ( which I read from another review). I had a different sunny model bike before purchasing this one. When I was ready to upgrade I didnt even have to hesitate before ordering from sunny health and fitness again. Their bikes are reliable, sturdy, quiet for the most part (unless theres an issue), and the customer service cannot be beat. They are always available to help and have spare parts for purchase ( or for free if you're still under the warranty). I definitely recommend this bike and especially this company

After a lot of research on spinning bikes I chose this one because of the magnetic resistance, belt drive, 44 lbs fly wheel, 4 way adjustable handle bars (the knob to move the handle bars front and back is on the the handle bar base, not below) and my budget. This bike is great. It’s sturdy, quiet and fully adjustable. When I bought it, it came with free expert assembly. The tech put the bike together in about 15-20 minutes. It probably would have taken me twice that . It comes with the handle bars, seat and post, pedals and two floor support bars detached. The frame, flywheel, resistance and pedal crank are already put together. The bike comes with caged pedals and they look really sturdy. It will support the max weight for the bike. I had SPD clipless pedals handy so I had the tech put those on instead. The bike seat exceeded expectations. It is a good size and is surprisingly comfortable... I did not have to use my gel seat cover like I do with gym bikes. The only negatives I have are the lack of bike computer for cadence and speed (heart rate too), water bottles holder is too low in my opinion and fire and aft adjustment lever on the seat is a little long (if you move your seat forward, the tightening lever may hit the back of your leg when you pedal. I added wahoo cadence and speed sensors on the bike and use their app to read the numbers but it would be nice if the bike came with the bike computer.

With the COVID-19 pandemic, my wife and I were looking to get a spin bike for home. We were originally deciding between this bike and a Schwinn IC4. Unfortunately, the Schwinn was on a 2+ month backorder, so we decided on this one. The good: This bike does seem very high quality. It is very sturdy and the magnetic resistance adjustment is very smooth. The bike is also very quiet (I haven't run into the clicking issue that some others have reported). We have done 30 workouts with the Peloton Digital app so far and we have had a great workout on the bike. Questionable design choices: There are some questionable design decisions that were made with the bike. I am 6'3" and my wife is 5'3", so we need to change all the positions each time we ride. I am not sure why they decided to put the saddle horizontal adjustment and the vertical seat adjustment on the same side. In order to move the seat to the lowest position for my wife, I have to first move the seat back and then forward again once the seat is down. The other questionable placement is the water bottle holder. It isn't easy to get to while sitting on the saddle. Also, I wish there was a way to move the handle bars closer that the closest setting. What's missing: As I am sure you are aware, this bike has no electronics and thus no resistance display. I saw on the Sunny website, they now have a Pro 2 version that has one (but it isn't available on Amazon, and is a bit more expensive). I did notice it is 6.25 turns to go from 0 - 100 resistance on the bike, so each quarter turn is about a 4% increase. Peloton experience: If you are like me, you are interested in getting a Peloton like experience, for a fraction of the price. To do this, you need a Tablet and cadence sensor (you can also pair your heart rate monitor). I wish this model had a built in tablet stand (I was looking at a different model that had one, but it was sold out). I am currently using the Wahoo cadence sensor which has worked very well. Just start pedaling and you should be able to get it synced into your workout from the sensor button. Overall, I am very happy with the purchase. A resistance display is the one thing I really wish I could get, but it hasn't been too bad doing math in my head to keep track of the approximated resistance.

I ordered this on March 21, 2022 My PCP told me I needed to start exercising in a way that was better for my knees, so cycling it was. But I live out in the county and it is primarily gravel roads, so I ended up deciding to just get a stationary bike first. I'm a large man, 250lbs and 6ft6" tall so it was a lengthy search finding something in my budget that would work for me. My legs were still a little too long for this bike but it was close enough I could still use it without feeling overly cramped. Assembly was simple and it feels very robust, I was actually impressed by the weight and rigidity of the materials. I get zero flex or wobble after properly adjusting the feet heights on my tile floor. I had doubts about the durability of the belt drive system, but so far I haven't had any issues and it's definitely much more quiet than some older chain drive stationary bikes I remember riding in the past. There were a couple things that were a problem though. The bottle holder placement is very awkward while riding. You can't exactly coast on these like a regular bike so grabbing a water bottle while peddling is impossible for me, mostly due to my height. I really wish these had other optional mounting heights and locations. I'll likely drill higher holes and install some rivnuts to move it up. But for now I've just been stopping to take a drink. And the other issue was the seat. I absolutely HATED the seat on this thing. It did not fit my anatomy at all and was way too squishy in all the wrong places. I now have a properly sized Brooks bike saddle installed and it makes a HUGE difference. Soooooo much more comfortable! so much so that I can ride this thing for hours without my butt hurting. And The seat mounting bracket can be removed from the original seat and be transferred over to the new saddle. Was a very easy process. Also, based on the advice from a friend that is an experienced cyclist I determined where to better position the seat for my long legs and increase comfort even further. But to do this I had to modify the mounting bracket. Even after adjusting everything to the maximum position I still couldn't get a proper leg extension. But after the modification it is absolutely fantastic and due to the build quality I don't expect to need a replacement for many years. With the seat so far back I did occasionally rub the riser post with my thigh, but it's nothing painful, was just barely brushing up against it. But after getting some proper cycling bibs it never happens anymore due to the compression at the thing. So if you're slightly too tall for the bike, you can drill a hole in the seat post plate and flip the plate around and then bolt it on to get more length. BUT it's not easily adjustable now, so if you have multiple riders In the house I don't recommend this.

Really happy with this purchase. The machine is quiet and sturdy. It has a small enough footprint to fit in my living room. I have 7.5 foot ceilings and there is plenty of room above my head. The box arrived with some damage but the bike was packed well with Styrofoam and each component was wrapped in plastic to avoid scuffing. There was no missing parts or damage to the product. It is extremely heavy but was wrapped with plastic strapping to get a grip on it. I was able to drag it from my mail room down the hall and up a small flight of stairs all by myself. Assembly was nerve racking but did not take more than an hour. It is really solid metal and very durable I think this should last a very long time. I installed a bike seat that I had for a beach cruiser bike on the Sunny exercise bike. It is wider, better cushioned and has a springs built into it for less impact. It also has relief for the tail bone area which I need. So all in all this was just a perfect transaction. Shipping was free and fast, very fast. I got the pro model instead of the pro II model so it does not have any electronics. I like the fact that there is no plug, battery, or display which may break over time. The bike stays put when mounting and riding. The pedals are very secure and the straps are adjustable. I am 5'11" and the bike fits my body well. I am currently 250 pounds and feel well supported by the machine. The only flimsy part of this machine is the water bottle holder it is made of plastic and aluminum. I don't really plan on using it and might just throw it away. Good luck finding a better machine for this price lol!

We researched a number of different indoor bicycles before buying this one. This one seemed to have the highest rankings and was still a reasonable price. This bike was very easy to assemble. The directions are clear. What we first found is it is VERY quiet to ride, which was a nice surprise. We have an open concept apartment and my husband was on it in one area and I was in another and I could not tell he was on it until I went looking for him! There are lots of ways to easily adjust it so that it fits your body. We got a tablet holder separately, which was a great addition. Tension is easily adjusted also. Small footprint, doesn’t take up much space. We got a mat also, so it won’t scuff up the floors. It’s a VERY sturdy bike and heavy, so you’ll probably need two people to get it out of the box and assembled. But after that, one person can move it because it has wheels on one end. I am a smallish female and I could move it short distances if I needed to. Comfortable seat. We are both able to get a great workout on this bike. We’ve had it for a week, but so far we absolutely love it and are very happy with our purchase.

I've had this since 2018 and use it a minimum of 4 times a week for 30-45 mins per day. It's a simple matter of rolling it out of the back room where it is stored and into the living room where I can spin in front of the tv. The only thing I've done is replace the seat twice. Apart from that, it's super easy and smooth to adjust the tension on the fly, up or down. Pedals are solid. It is heavy which allows it to anchor solidly while in use. Expensive. Yes. I don't want and would never use any of the added on gadgets, so I don't miss them at all. It's a stationary bike. That's all it is. And it works. And has worked for going on 7 years now.

2nd UPDATE- It took me filing a complaint with the BBB for the company to return my emails regarding the damaged bearings. They finally sent the parts, with no instructions on what to do. It took another email for them to provide me with an Amazon link for a tool I would need to purchase, along with links to 4 videos of doing this repair on a completely different bike. There is a very good chance of further damage to the crank, if this repair is not done 100% correctly. I will work with the BBB and Amazon to get this bike replaced if they refuse a 100% refund. UPDATED- the company will not return any emails and you cannot get anyone on the phone. It looks like they are not honoring their warranty. I would not recommend purchasing from this company. Original review-I purchased this bike in January of 2020 and things started out pretty good. The assembly was quite easy and the bike itself is very sturdy. The problem started a couple of months in to using it on a regular basis. I first noticed a little noise, however it wasn't too bad and didn't seem to effect the performance of the bike. Flash forward several more weeks and the noise suddenly got worse and you could feel it effecting the bike. I did some research and found out their have MANY quality issues with this bike, especially with noise developing from a faulty crankshaft. I contacted customer support towards the end of May and was asked to provide a video of the issue, which I did. Customer support diagnosed it as potentially having a bad bearing and informed me they would send out replacement parts. It is now 3 weeks later and I have not received parts or a response to my email asking for a delivery status. When/if I receive the parts, I will update this review. For now, please do some research on issues with this bike before you purchase it.
