Indoor Intensive Cycling Exercise Bike, Adjustable Cardio Training Exerciser w/Emergency Brake for Home, Optional Free SunnyFit App Bluetooth Link + Electromagnetic Resistance

Yes, I mulled over several spin bikes, so I'm aware of how important these reviews can be in the decision process. Looked for new and on Craigslist, refurbished, etc. Almost got either the Peloton, Echelon, Bowflex C6 a refurbished Keiser and the Schwinn ic4. But, during my constant obsessed reviewing process, and having taken several spin classes, I narrowed my desires to 5 things: Sturdiness. Noise level. Price. Price. Speed of delivery. Sturdiness was based on the weight the machine could hold. I'm 5'10, 200lbs, but I know I can be gentle and then gorilla-is so the bike had to be strong. Noise Level. Although I have it on my patio, and where I live is a bit noise isolated already, I dont like to hear any fitness machine Im working on. Price. I wanted to feel like what I was paying for was a bargain and comparable to many higher end bikes. Price. I didn't want to spend money on something I'd also use in a gym and Amazon had a special monthly payment thingy that made it a cool way to pay for the bike. Speed of delivery: Although when I initially ordered it, it was supposed to get to me in five days which changed to two weeks due to Covid-19 issues, it was still faster than any other of those bikes outside of the refurbished ones off Craigslist. And I was really impatient. Had Bowflex or Schwinn said I can have it in less than a week, I'd prob went with one of them. Conclusion: This bike is really cool. It's only been a month so keep that in mind when reading this. But it is sturdy, really really quiet, and you can sway left to right without worry. I not sure if I'd get this if I were taller than 6'2" with long legs because I think it may be a leg issue problem. Not sure. The bike was really easy and simple to assemble (less than 45 mins) and it took longer taking it out of the packaging than assembling. I place my iPad on the bars (bars have a nice, soft yet sturdy feel) as you can see and the case has a strap that holds it around the bar. I tried a clamp/ipad holder but didnt like placement. Prob easier to just watch tv or something. There is good resistance although changing levels is ehhh especially when in climbing mode because it takes a bit dexterity to lean down and increase or decrease tension. The pedals are cool (only used cages so far) and will prob get shoes with clips soon. The ones I have need SPD to fit and I dont like em anyway so Im not gonna use em. The monitor is ok. I use the it for cadence and compared my Heart rate to my Apple Watch. The magnetic resistance is smooth and I dig it. The bike could use a brake though but since the pedals are so fluid, stopping is simple. The bike is actually nicer and more professional looking in person. I know its hard to tell buying online, and if you haven't rode the one youre reviewing, its hard to know. I had never heard of Sunny until I start looking for a bike and I was biased towards Schwinn, Spinning, and all the other name brands. I still am, but after purchasing this, I'm glad I was open to it. I started using the Peloton app, but now use other spin cycle youtube videos. Since I am a trainer, I kinda can create my own workout, and some of the coaches on those workout apps talk way too much (for my taste) but I'm sure many will find that helpful and motivational. All in all, I say do it and if you are gonna get a bike for use 2-4 times per week, invest in one that can accommodate at least 50lbs above your weight, is quiet, and you'll get your money's worth (2x/week x $20 spin class)=$1920yr. Imagine that.

For several months I've been scouring Craiglist looking for a used Schwinn IC4 indoor exercise bike, but they tend to get snapped up as soon as they are listed. I wanted a bike whose LCD computer tracked cadence. I also wanted a bike featuring magnetic resistance with levels of resistance that could be easily set and tracked. I didn't want to count twists on a resistance knob. So when I saw reviews for the Sunny SF-B1709 that described the clicky resistance lever, it seemed like precisely what I was looking for. So I put in an order. Assembling the bike wasn't too much of an issue for me. If you can assemble Ikea furniture you can probably assemble this bike. Once assembled I was impressed with the quality. This thing is solid and well built. The resistance lever works as described. Honestly, it's great. While I would like to see actual resistance numbers or a scale displayed somewhere, it's not really all that necessary. Moreover, the resistance itself is plenty for a good workout. There's nothing more disappointing than a machine that doesn't provide enough resistance even on the highest setting, but that's not an issue here. You'll get a good workout even 2/3 of the way up. This machine is about one third the price of an IC4, and for that kind of money it's a screaming deal. However, it is not without its issues. The heart rate monitor, for instance, seems a little inaccurate to me, at least based on what the bikes at the gym tend to tell me. I think this one reads low. The second issue is a bit more annoying. When I got the bike set up, I noticed that it made an annoying squeak while pedaling. After contacting customer support they instructed me to partly disassemble the unit and examine the interior to pinpoint the source of the squeak. This involved removing a shell, which comes already assembled from the factory. More significantly, it involves removing the crank arms which are an absolute bear to get off. Even after unscrewing the holding screw, I had to spray them with lubricant and smack them with a rubber mallet to get them loose. Once that was done I managed to get the shell apart and lubricate the bearings, which solved the problem. the bike is now whisper quiet. It would be nice if Sunny had built in an access port to make it simple to lubricate the various moving parts behind the shell. I don't look forward to removing these crank arms again if the bearings start squeaking again. It would also be nice if these bits were lubricated before shipping. In reading other reviews it looks like I'm not the only one to experience this issue. All in all, however, this thing is solid and a great deal. I'm a bit disappointed that it was squeaking when I first set it up, but I don't regret my purchase. I saved a ton of money versus comparable exercise bikes.

I love this stationary bike. I would absolutely recommend that this is the one that you purchase. Even if you're looking for an entry-level price-tag, spend a bit more and get this bike. You won't be sorry. Let me tell you why. 1) It rides incredibly smoothly, silently and is very comfortable. It accommodates tall, big people. I am 5'9" tall and weigh 200 lbs. My daughter is 5" 11" tall with ridiculously long arms and legs and weighs 120 lbs. My husband is 6'3" tall and weighs about 220, with enormous size 13 feet. All of us fit this bike properly. There are lots of ways to adjust it to your comfort level and for what you will be doing. I love to do The Trip by Les Mills. This has a lot of standing and I want my handlebars to be in a very specific position. Absolutely no problem. My daughter likes to work on her singing as she rides the bike by singing along to videos. Her adjustment needs to be different from mine. No problem. My husband just likes to get on the bike while watching TV and get some exercise. Absolutely no problem. This bike adjusts just as well as, if not better, than the bike I used at the gym, which I really liked. I'm sure that, even if you are short, the adjustment will be no problem. 2) THIS IS THE RESISTANCE MECHANISM YOU WANT!!! Why on earth would anyone use one of those stupid turning knobs for the resistance, when you can just use this perfect lever??? I honestly just don't get it. The bikes that they had at the gym that I used to go to had levers and I wanted a lever as well. However, I initially cheaped out and got a horrible bike that had the knob that you turn. It was awful. All the turning and twisting when you want to go from a light resistance to a heavy resistance. Ridiculous. On this bike you just push down the lever to the resistance level that you want. It's instant. It's smooth and it gives you great incremented resistance. When you do The Trip, they want you to go from heavy climbs, right into fast downhills. I would miss part of the workout while spending all that time, energy and attention twisting the stupid knob. Forget that! I just push the lever up or down. It's fantastic! 3) This bike is STURDY (and easy to assemble). This bike weighs right around 100 lbs. About 25 pounds more than the crappy bike I first purchased. This thing feels good and sturdy. Hubby and I aren't light-weights, but the bike feels perfectly capable of handling whatever we dish out to it. Also, it was very easy to assemble. You're given all of the tools you need and the instructions are pretty clear. Also, it's not all that complicated. I could have figured it out without any instructions at all. I wasn't rushing when I put it together, just taking my time, and I put it together, by myself, in about 45 minutes. Most of that time was spent unboxing the thing, which is REALLY well packed. The health monitor on this bike is functional, if rudimentary. I might look into a better monitor. Or maybe not. I really am just interested in the calories burned and the results that it has given me have seemed to be accurate. Someone mentioned that they didn't like where the water bottle bracket sits between the handlebars. I found it to be very convenient, and, again, sturdy. I'm watching the TV which is mounted on the wall in front of the bike, so I don't need an iPad mount or anything of that sort. I did not use the seat that came with the bike, as we had purchased a much better seat for the other crappy bike, to replace it's horribly painful seat (I purchased the TONBUX oversized seat, which is great). I will say, though, that the seat provided with the bike looked very good and comfortable, and probably would have worked without being painful. I just have an extra seat when needed. I have only had this bike for 3 days, so I can not attest to how well it holds up over time. The other crappy bike broke within 45 days (the stupid turning knob froze up), ONE DAY BEFORE I COULD NO LONGER RETURN IT. This one feels very well made, however, and I will update this review after we've had it for a while. I did purchase the extended warranty, however, just because the warranty isn't that great and boxing this thing up would be a nightmare to box up and return. Overall, I would challenge you to find a better bike for any price. This is the one you want to buy. BTW, the crappy bike that I purchased first and returned was the "pooboo Magnetic Exercise Bikes Stationary Bike Belt Drive Indoor Cycling Bike Fitness Bike for Home Cardio Workout Bike Training with LCD Monitor". DON'T BUY THAT ONE.

I bought this bike about 2 weeks ago and have already rode it 115 miles. This bike is wonderful! I did research and looked countless hours for a spin bike that could match, or come close to the Keiser M3 for much less, and this bike delivered! It’s easy to put together, exceptionally sturdy, smooth, and quiet. The 4 ways of adjustment to the bike’s seat and handlebars allows for nice comfort and fit as well! The lever may consist of only 13 levels of resistance, but the intensity of each is just right and can nearly go toe-to-toe with other competitors like the M3. If you’re looking for a similar ride that you most likely found in a spin class then this is the bike for you! It can’t be beat, and for nearly half the price of other models and is an exceptional bang for your buck! In short, I’ve listed some pros and cons below. Pros: -Affordability -Magnetic resistance; Don’t have to replace felt pad -Rubber belt drive; No obnoxious chain noise -Rear 8lb flywheel; I’m biased, but really enjoy the feel over heavier front driven flywheels. -Can use cycling shoes -Display; can monitor cadence, speed, distance, calories, time, and a few other stats Cons -loose pedal; tighten them up good before you workout or they’ll making clunking sounds. (My initial error lol) -Front handle bar design; love the handle bars on the bike, but if you’re getting into a serious workout with ups and downs the tube the handles sit on will cause the them to move slightly (Can be tightened though to reduce it) - Seat drop; I like when seats come down further so I can get into some serious hovers. The bike drops enough, but I’d like to see a little more drop personally. - Heart Rate monitor; Not accurate, but didn’t buy it for that. Would be a super nice feature though to have a more accurate reading in between sprints and hill climbs....but you can buy an accurate heart monitor anywhere so not really an issue. All in all this is a solid bike and cons are barely cons. I highly recommend this bike! If you don’t want to spend 1000+ this is the bike for you! It’s mid-ranged in price and can do just about as good as other top of the line models and brands. As a spin instructor, avid triathlon enthusiast, and a guy who loves to save money I enjoy it!

This bike is very well made, I am glad I purchased it. I got lucky and got it at less than $300. It took some time for me to finally pull the trigger and buy as I was reluctant due to the low price. As the saying goes, you get what you pay for and in this case my money was well spent. The only negative so far is the seat. This can be fixed with a seat pad. This bike was super easy to put together and is very quiet. I live in an apartment and I have no worries of my neighbors below hearing.

This item has lil dings all over it, the bars are warped (lever shows even, but you can see one side dipping) and one of the pedals will not stay clipped. I adjusted the leveling feet, and adjusted the pedal tension. It seems like this bike was just dropped on it's right side. On the plus side, if you get a good one it feels nice and is nearly silent. I like all the adjustments and the flywheel is challenging enough.

I bought this bike because I could not go to the gym, like many of us in 2020. I was swayed by the reasonable price and the lightweight flywheel. The bike arrived relatively quickly and was easy to assemble. The manual was misprinted in a few places, but I was able to assemble it with the help of another person. The seat is tricky to get situated, but we managed after a few tries. I was thrilled to be able to exercise at home. There was a tiny hitch - a tiny bump when the wheel turned - but it did not get in the way of my ride, at first. Within a month, the bump was getting bigger and bigger. It was starting to affect the ride and I wanted to protect my investment, so I contacted support. First, support takes forever to get back to you. There was an extended back and forth as I verified my purchase. They also requested video of the issue. Then, they sent me a link to a Youtube video to take off the belt cover. Then, asked me to diagnose the problem and ask what part I would need shipped (yes, using the unreadable diagram from my misprinted manual). Here was the first problem: the video was a completely different model, and would not work for this one. In the video, the belt cover could be removed without removing the crank arm. Not so with this model (see picture). The plastic casing encases the crank arm, and it must be removed to get in. I asked them for further instructions for the crank arm. I did not want to void a warranty doing anything stupid. I did this twice. Radio silence. I finally googled and found another video of theirs for removal of the crank arm. It took two of us and half a canister of WD-40. We finally persevered but I still have not been able to diagnose the problem. I think the wheel may be installed improperly or bent, but I can't totally tell. Even if I could properly diagnose it, I don't have faith I would hear back from them or get the parts I need (OR be able to put everything back together again!). I feel completely let down by customer service. In the meantime, I have a completely unusable machine and no response from the company. I do not recommend this company. If you must go with Sunny, please choose a different bike! They have no way to actually help you take this one apart if it needs service. They will send you instructions for a different bike and then ignore you. I should have spent more money and gotten a Keiser.

As many others, I did much research on this new spin bike purchase. While many features come down to personal preference, the big question for me was deciding between a heavy vs light flywheel design. TLDR Summary : Heavy vs Light Flywheel : Traditional thinking was that you wanted a heavy flywheel to up front to simulate a smoother ride and less choppy pedal stroke. Nowadays, some bikes use lighter flywheels that spin faster to create the same result. The big difference is that heavier flywheel weighted bikes have a tendency to pull the legs through the full 360 degrees of the pedaling action, putting unnecessary pressure on the knees and actually removing the need to recruit muscles (i.e. they can get lazy). On the other hand, lighter flywheel design promotes hamstring and glute recruitment on the upstroke of the pedal stroke helping you to work harder throughout and prevent injuries. Ultimately we decided to go with this Sunny Health bike ($600) which has the lighter flywheel located in the back, with belt drive and magnetic resistance. It is similar to the higher end Keiser m3i you see in the gyms that everyone loves, but the Keiser is still pretty pricey at $2k. So far we are really happy with this purchase and like the Sunny coupled with the Peloton app. Its a very smooth ride with no 'choppiness' and plenty of easily adjustable resistance. We didn't experience the crooked handlebar issue others have, this seems to have been fixed. There are a few things that could be better. The biggest con for us is the flex in the frame/handlebar assembly when pedaling hard. Some riders like this, but we aren't heavy people (<170 lb) and I find the movement to be excessive. Pro's: -Super smooth ride and it doesn't feel like it could tear/stress your ligaments like the heavier flywheel bikes. -Really quiet -Built in heart rate monitor and cadence -Belt drive is durable and quiet -Magnetic resistance is quiet with many settings -dual option pedals take clip-in cycling shoes on one side, have cages on other Con's : -Has a decent amount of flex in the frame when pedaling hard (some people like this). -Water bottle cage is in a non convenient place up front under handle bars. -No built in tablet holder, but we balance the ipad on the handlebars and it works pretty well -No built in rack for small weights Options to consider in purchasing any spin bike: 1) Resistance - magnetic vs friction/physical -Magnetic is quieter with less maintenance, but less absolute resistance and more $$. 2) Drive - belt vs chain -Belt is quieter/smoother with less maintenance, but more $$ 3) Flywheel - positioned in front vs back, light vs heavy, -Location : Positioned in the back keeps it out of the 'sweat zone'. -Heavy vs Light : Traditional thinking was that you wanted a heavy flywheel to up front to simulate a smoother ride and less choppy pedal stroke. Nowadays, some bikes use lighter flywheels that spin faster to create the same result. The big difference is that heavier flywheel weighted bikes have a tendency to pull the legs through the full 360 degrees of the pedaling action, putting unnecessary pressure on the knees and actually removing the need to recruit muscles (i.e. they can get lazy). On the other hand, lighter flywheel design promotes hamstring and glute recruitment on the upstroke of the pedal stroke helping you to work harder throughout. 4) cadence/heart rate monitor/computer 5) tablet placement/holder 6) weight rack/water bottle holder and placement 7) pedals - clip in, cages or both
