Smart Indoor Cycling Exercise Bike for Home Cardio

Overall -- I've had the bike for about 3 weeks. This thing can really give a butt kicking workout. It is heavy and appears like it will last for a long time. What you get is a basic heavy-duty bike with no frills and almost industrial equipment like looks. You can easily add any features later. For example, I may buy a cadence tracking thing in the future, but it's not a necessity. I'm happy with this purchase. This thing works great.Ergonomics -- The seat and bars are firm. I have some padded biking gloves that helped, but it's not a big deal really. The sound of the chain is not particularly bad at all. Also, I have heard no screeching or squeeling-type noises. I think my heavy breathing might be equivalently loud to the chain. Anyway, I like to use headphones for a laptop for watching youtube cycling workout classes while on the bike. So, noise is not an issue. You could buy the belt version of this bike if you wanted potentially quieter operation. However, that version had lower Amazon reviews. Also, I think a chain is more reliable and replaceable by any standard bike chain if needed. Also, I did zip-tie on a plastic holder in the handlebar loop for a water bottle since it doesn't come with that. EDIT:bought a new seat for $20, and it makes the workout more comfortable.Install -- Installation is very easy. At the same time, have a little patience, read the instructions, and don't strip any bolt threads in a rush. After riding the first few times, I had to retighten the handlebar bolts slightly. This should be expected, and it hasn't loosened since. You could use locktite if you want, but I don't think it necessary.Maintenance -- Based on other reviews; I bought some dry silicone lubricant spray at the hardware store (Brand I used - WD40 Specialist Water Resistant Silicone Lubricant). I removed and sprayed the friction pads. Then, let them dry overnight and reinstalled them. The instructions for the friction pads removal is in the users manual. I also rubbed with a cloth some silicone on the flywheel where the pads touch, and let it dry. I did this lubrication at the start, and didn't wait for any friction issues to pop up. This has worked well so far. I will likely reapply silicone to the flywheel every so often. I also completely loosen the friction pad tension after each ride is done. This was mentioned by another reviewer. I imagine this might allow the felt pads to expand back slightly, but don't really know if it helps or not. EDIT:Found I need to reapply the silicone spray to the pads and wheel contact surfaces every 2 months or so to prevent a whistling/humming noise from appearing when resistance is applied.

Hi all, I bought this cycling bike through Amazon in the hopes of getting back in shape. In juggling multiple jobs, schools, and commuting, I did not have much free time for exercising. After reading dozens of Amazon reviews, I finally chose this bike.I paid $184 at the time (it was on sale) and waited excitedly for my new Sunny Health & Fitness Indoor Cycling Bike.Pros-Delivery was prompt-Upon opening the box, it looked very complicated: BUT everything one needs was included in the box and the directions were easy to follow- I was set up and testing in 20 minutes- The machine operates on a resistance basis (there is a knob you turn for resistance)- It is not SILENT (for those who wondered) but the noise is very minimal (I could not hear it over my music playing from my laptop several feet away).- The wheels (you install during setup) allow the bike to be easily moved from room to room- Seat is adjustable and so are the handle barsCons- Working out too hard can cause a faint burning smell (the bike uses Styrofoam pads for resistance and this wears down)Honestly, I do not believe the Sunny Health & Fitness Indoor Cycling Bike has any real issues. The burning smell is faint and after the first minute it becomes unnoticable (probably because I'm absorbed by the training and because the smell was always so faint). I have been using mine for half a year now yesterday (time flies!) and I have not had any problems with it.I thought the bike would be cheaper quality because of the price but the chrome cast finish and the metal on the bike are very solid. As previously mentioned, the bike is nearly silent (because it does not use chains for resistance but a wheel with Styrofoam pads) and this is great for me as I workout early in the mornings or late at night (and my downstairs neighbors have not complained).I would recommend this for anyone looking for a good way to get in cardio and burn fat. I used to be a cross-fit athlete and ran cross country, outdoors, and indoors. I was never really a machine person, but this bike gives me the flexibility to work out at home and I can really turn the resistance up. Anyone who is new to spinning (as I was when I bought this) or even a veteran looking for a personal bike will definitely enjoy this.TIPS:- Please note, the package it comes in is heavy and I do not recommend carrying it up alone or even in the box it comes with. It is much easier to take out the biggest/ heaviest pieces first from the box. I took out the frame for the bike, all one piece, and the wheel individually and carried the box up after with just the small parts and pieces in it.- I recommend using Youtube to search for videos to spin along with (they are free and great - I use ones on endurance and fat burning via intensity interval training).- Get a routine going, it makes working out a bit easier.- A proper diet is necessary with any workout, otherwise you are fighting an uphill battle.Definitely cannot go wrong buying this product, enjoy!Best,Sadik

I've got a variety of physical conditioning gadgets in my basement. The usual incline/decline weight bench, some yoga mats and I've got a ProForm treadmill that my wife and I compete for time on. When Christmas came around I started looking for an add-on to the "home gym". We're in our mid-40s and wanted something a little less impact on the knees. I looked at elliptical runners, combo runner/bikes and then I came across these 'spinner' bikes.I read a ton of reviews, looked at the physical specs, and took a shot at this Sunny Pro Indoor Bike. The price was incredible and I really appreciated the video review posted by Brandon Taylor. Nothing beats being able to see something in action when you're talking about making an online purchase.Here's my input for your consideration.WILL THIS BE A GOOD FIT? I'm 5'10" (185) and my wife is 5'4" (120). The seat and handlebars adjust to setting that fit both of us no problem. That was a major concern for me because if it was too big for my wife the gift was a bust.CAN YOU ASSEMBLE IT? This came with everything you need to put it together. All the bolts, screws, washers, and hand tools. I'd recommend you pull your own household crescent wrench out of the tool box to help with installing the pedals, but not necessary.HOW LONG DID IT TAKE TO PUT TOGETHER? I'm a step above Tim the Tool Man Taylor with home projects. I'm handy enough not to end up in the hospital put it that way. From the time I opened the box, it took 30 minutes. By myself. That's pretty good. I'll post some photos so you can see a few steps.IS THE BIKE QUIET OR NOISY? I'm no spinner bike expert, but I've got this bike positioned in the basement near the TV so I can watch those Virtual Running/Cycling DVDs and I think it's quiet. Even if my kid wants to watch his cartoons, I can ride, TV volume stays at a normal level, and I'm totally not disturbing him at all. Doesn't even know I'm there. The only time there's even a hint of noise is when my pedaling gets a little out of pace/sync. Otherwise - this is a solid and smooth ride.ANYTHING BAD ABOUT THE BIKE? Like other reviewers - that seat is hard as a rock. I got the Mongoose gel seat cover and that helped, but after a 30 minute workout, my backside is still stinging. We'll be shopping for another seat.I had some minor "damage" out of the box from shipment (see the photo slideshow). The styrofoam shifted and that white foam basically adhered to a spot on the handlebars. There must have also been rubbing in the box as the paint on the tension-knob was scratched up. Totally superficial and wasn't worth really getting bent out of shape about. Especially on Christmas morning as I'm discovering this during assembly.That's why I only give 4 stars. Had there been no damage to the bike - I'd have given 5 stars.WOULD YOU RECOMMEND THIS BIKE? I absolutely WOULD recommend this bike to my family and friends.Good luck on your hunt for home exercise gear, and thanks for reading.

Update Post: We originally purchased one of these bikes in June of 2015. We were a bit concerned about the low price because our intention was to use it in our fitness facility. This bike is rock solid. We now have 9 of them and will be purchasing 2 more this month. The bikes are used in spin classes daily. We have everyone from small, uber-fit petite women to hulking 6'2" 255lb men. These bikes get hours and hours of use each week. I recommended this bike to an associate who is opening a fitness facility. When he was purchasing some high-end equipment from a well-known gym equipment provider, he asked them about the bike (showed them the Amazon link I sent to him) and they were dumbfounded. They said that the bike had quite impressive features, especially for a bike that inexpensive and appeared to be a very, very good bargain. They actually had the bike on their computer when he went in the next day because they researched it more and said they were quite impressed by it. That, and the fact that their lowest priced bike was a bit below $900 reassured us that we made a great choice! We have even used these bikes in the parking lot for some special events.The only problems we had with the bike were with the screw on the tension knob on one. The bolt became a bit stripped and we had to order another one. The other issue with another one was with the brakes squeaking after about 8 months. This can happen if you don't "oil" the flywheel periodically because the brakes get dried out. A bit of treadmill oil on the flywheel fixed this immediately. We service the bikes bi-weekly, and that involves tightening the bolts on the seats (just to make sure they stay put) and just doing a check on all the bolts and moveable parts. But again, keep in mind that these bikes get literally hundreds of hours a month, so that minuscule amount of service is -wonderful-!If you're looking for a cost-effective, very dependable bike, you should definitely consider purchasing one of these. Absolutely worth it!ProsLow costVery easy assemblySturdy, solid constructionMinimal maintenance neededVery easy to move (we move these puppies a lot - even outside)Shipping was quick (and cheap - Yay Prime!)ConsThe brakes may squeak a bit after a while. This is resolved by oiling the flywheel periodically. (You should do this with any spin bike and make sure the tension is released after riding to ensure they don't dry a bit and squeak.

After comparing reviews and prices on a number of home fitness bikes, I narrowed my choice down to the Sunny Health & Fitness Pro Indoor Cycling Bike. Before I purchase an item on Amazon, I tend to read the 5 star reviews and then begin at the bottom with the 1 star reviews and work my way back up. This approach tends to give me a view of what people liked about the bike and, starting with the least satisfied customers, allows me to get a feel for the complaints and compare them to a variety of reviews.First, be warned. The box is heavy. I mean, really heavy. The shipping weight is listed at 112 pounds and the box is large. Believe it or not, this is a very good thing. The bike is solid, mostly metal with an absolute minimum of plastic. If the box was light, I'd personally worry. Additionally, the bike is mostly assembled when it arrives. Hence the large and heavy box.A number of customers expressed difficulty in assembling the bike. I did not find this to be the case at all. The design has slightly changed since the official photo was taken (the bike is essentially identical except for the handlebars - more on that in a moment) and I wonder if the company improved the assembly process as well. It took me approximately ten minutes to assemble the bike, all of the necessary tools were included, and the assembly was incredibly intuitive and required minimal reference to the instructions. There are not a lot of parts that need to be assembled - it's just after reading some of the reviews I was especially careful, thorough, and spent a chunk of that time studying the instructions and looking for the difficult part.The bike is solid. (According to the description, the front flywheel weighs approximately 40 pounds on its own and that seemed about right to me.) To assemble the bike, you attach the pedals (they screw on), put the seat and handlebar stems into the frame, and attach the handlebars and seat to the appropriate stem. The adjustment knobs over the entire bike had been screwed in slightly too far at the factory so that the shaft of the bolt blocked the entry of the stems. Simply unscrewing each slightly solved the problem. The cross pieces of the base come with small metal blocks in place and they need to be removed and the actual wide cross pieces (the front piece has the small red wheels attached in the photo) need to be bolted into their positions. That's it. Assembly is complete.All of the parts (tools, nuts, and bolts) come shrink wrapped to a stiff piece of cardboard. Each part is clearly labeled on the board. Instead of looking for "Hexagon Flat Round Head Screw-Black M10X25mm" you simply find part "(66)". This is an exact example from the assembly process. (The "Flat Washer-Black" is part "(67)" and the numbers are clearly referenced in the instructions.)There's no searching for parts. You simply remove them from the board as needed.The only issue that I had was that the tension control knob for the flywheel was stuck. The knob literally wouldn't turn. Cranking on it really hard popped it free and it works fine. I'm not sure what happened - once it was unstuck, all was good. It works fine and just like new. It wasn't a defect, it was just initially stuck and now works fine.The handlebars are different than shown in the photo. Instead of two small bars that come out at 90 degree angles toward the inside of the handlebars, those bars are now connected with a large comfortable arc. In my opinion, this is a significant improvement over the original design and gives you a much wider range of options for hand placement.I spent several years attending the 5 AM spin class at my local gym. Being the first to use the classroom space, we early birds took the bikes from where they were parked along the wall and moved them to their positions. Having spent a lot of time with those bikes, I'm confident in stating that there is very little difference between this bike and the professional models used at the gym. I would rate it low-end professional, very high end amateur, and an absolute steal at the price.The ride is essentially indistinguishable from high-end gym spin bikes. Having ridden those bikes roughly 1,000 times, I can pick up on subtle (and I can't stress the word "subtle" enough) differences, but they do not detract from the ride in the slightest. For instance, the knob to adjust the tension has a little more play in it (a half turn adjusts the tension a little, then a tenth of a turn adjusts it a lot) but it's still very easy to get it set exactly where you want it, you just have to become familiar with it. The bike remains incredibly solid in both seated and standing riding positions and exceeds all of my expectations for a home spin bike.To address a couple of reviews that I saw while considering my purchase.The angle of the seat was mentioned by more than one person. I'm not sure what their issue was - it adjusts just like any other bike seat, including the angle. In other words, by loosening a bolt, manually adjusting the tilt, and tightening the same bolt once more, you can have the seat at any angle you wish. It's literally a non-issue.A couple of people mentioned the noise. It's not silent, but I'm not sure what folks were expecting. It doesn't make an unusual amount of noise and its mostly noticeable simply because there is no other unexpected sound in the room. I watch shows while riding and don't have any trouble becoming immersed in the program. My wife and I can actually have a conversation at a normal volume while one of us is riding. The noise is much lower than I anticipated given the reviews that I read and very acceptable for this piece of equipment, perhaps even on the low end of the noise range.At least one review mentioned an odd smell while riding. I did not experience that at all.Spin bikes don't typically come with odometers. With cardio, the duration of your ride is much more important than how far you ride. I realize that this may bother some people, but an odometer, in my experience, would have been out of place on this piece of equipment. A couple of reviews downgraded the bike because of the lack of an odometer, but I ride for a set period of time, not for distance. As one of my friends jokingly put it, "Why do you need an odometer on a stationary bike? Do you want to know how far you rode? You didn't! It doesn't move!"This one gets five stars from me. Simply put, this is an extremely good deal for the price. An absolute bargain. There are little things here and there that could be upgraded, but only at substantial cost. After reading a large number of the other reviews, I can honestly say that the Sunny Health & Fitness Pro Indoor Cycling Bike exceeded my expectations by a wide margin. I highly recommend it.

Sunny's SF-B901 spin bike (see the official product description at sunnyhealthfitness.com) is a great bike for the price. Picked one up a few weeks ago to replace a Schwinn 140 upright stationary bike. The 140 is great, but my wife and I started a spinning class and wanted something to use at home - the 140 just wasn't cutting it. This bike is a great choice for an entry level spin bike/first time buyer.SIMILAR TO SCHWINNThe construction, the layout and even the paint job look VERY similar to a Schwinn IC Elite or Schwinn Jonny G Spinner. Compare the silver-on-red star emblem on the SF-B901 flywheel to the Schwinn IC Elite and you'll see what I mean.MINOR ISSUES:SEAT POSTThe stem/handlebar post and the seat post are a bit wiggly. On my unit, the seat post would tap the inside of the seat tube while riding, making a "clinking" noise at each revolution. It doesn't feel unsafe, just distracting - and this only happens when the post was adjusted for short people like myself.The problem seems to be the square black plastic sleeve used to secure the seatpost to the seat tube: the sleeve doesn't go all the way to the bottom of the tube, which leaves a gap between the outer diameter of the post and the inner diameter of the tube. That gap lets the post tap the tube, creating the clinking sound. My solution: pull the seat post off the bike, slip a rubber band around the post and reinsert. The diameter of the rubber band fills the gap, although it does make raising and lowering the seat a bit of a chore. The real solution here would be for Sunny to lengthen the sleeve.FLYWHEEL HUBMy unit also seems to have a noisy flywheel hub. It clicks and ticks rythmically when I ride (has from day 1) which can be a bit annoying. Like the seat post issue, it doesn't seem unsafe, but seems like a cheap component. You wouldn't hear the noise if you had headphones on, but I bike along to a spinning DVD. I haven't tried removing and lubing contact points around the hub, but my guess is that the hub itself just needs to be replaced. You might be able purchase a replacement flywheel hub from fitnessrepairparts.com or krislynn.net if the hub dimensions match Schwinn flywheel hubs (part #60).BOTTOM BRACKETAfter using the bike for a few weeks I've begun to notice a bit of vibration and grinding when pedaling the bike under heavy resistance or when standing. Sounds like a loose bottom bracket.UPGRADES*Water Bottle Cage*No water bottle cage included with this bike. I bought a cheap bottle cage and mounted it to the side of the front fork.*Pedals*The pedals work fine and do include toe-cages. I had a pair of Shimano M324 pedals lying around so I installed them on the bike. The M324 is great for anyone looking to try clipless/SPD shoes as it has clipless on one side, platform on the other.OTHER NOTESThe SF-B901 drivetrain is chain driven, not belt driven, has hefty crank arms, the seat works well (although no center channel) and uses two side-mounted felt brake pads (again, like Schwinn, not like the single top-mounted felt pads used in Startac). The brake assembly isn't hidden like it would be on a more expensive bike, so wipe down the cables every once in a while. I did lube the brake pad material with a silicon spray to reduce noise, although I'm not sure how much of an effect it had.CONCLUSIONI could have spent a few hundred more on a nicer model or a refurbished Schwinn, and I still might try to replace the flywheel hub, but the bike is working well and I'm satisfied with my purchase.

I love this bike! It's perfect for me. I was slightly concerned before buying it as there were some that had issues with this, but I have not had any problems. Yes, the seat is hard, but it's supposed to be. Most bikes sold use a generic seat and those that have a problem with it usually replace it anyway. There's no way to find a one size fits all kind of seat on a bike as everyone has different tastes. The seat feels no different than my bike seat on the mobile bike I use to bike to the beach.This bike is so comfortable for me to use as I stay on it longer than I stay on my mobile bike. I can adjust the resistance so it's more muscle building rather than the lower resistance for those looking to lose weight. You can adjust the resistance to your own liking. The one issue I had was not the bike seat, but the petals where it has straps you stick your feet in with your shoes on. I realized that's never gonna work for me as my foot doesn't fit in it, so I just flipped the pedals around so the strap is in the other direction and it works perfectly.This bike is very heavy in the box. The base for this is definitely strong and solid. Doesn't move around as you bike. I feel bad for whoever is having to deliver these things, but I'm sure they're used to it and have hand trucks. I wasn't home when it was delivered so it was by my mailboxes. My unit is down the walkway in the back and up the stairs. The box recommends you have two people move this thing. I didn't have that luxury, but still managed to do it somehow solo. I'm considered super fit and athletic, yet even I couldn't lift this thing. Luckily there were straps around the box, so I used those as handles and rolled it like a wheel barrow down the walk way to my unit slowly, then up the stairs carefully. That was the hardest part of all this. It did zero damage as the bike unit is tightly packed and nothing was shuffling around. It all looked great and in tact once I opened the box upstairs.I read the instructions carefully before I started. You open the box on one end then roll it right side up and pull the box up leaving the bike firmly planted on the floor. It took 30 minutes to carefully pull all the parts out and place them around the area I was going to put this together. It then took another 30 minutes to put the bike together. After that, I was off and biking with no problem. The front has wheels, which makes it pretty light for me to move from room to room if and when I need to.This bike is $500 on the Sunny Health website, but I was lucky enough to find it on Amazon for $200, which is a steal for a stationary bike that also helps build muscle. The other bikes below that price were more basic and strictly for those trying to lose weight, which I'm not. I'm 5'7" and 150 lbs. Keep all of the tools and instructions somewhere handy in case you ever have to re-tighten anything on the bike. Things move and become loose like any other exercise equipment.As far as noise, nothing too major except a gliding sound of the wheels moving, just like my own mobile bike though. I noticed that the stronger the resistance I use for strength building, then the noisier the bike gets, but once again nothing too major. It does vibrate as you're biking, but when you're exercising you are going to making some kind of noise. That's just the way it is. All in all I'm happy with this bike and have had no major issues. If I ever do, then I'll come back and revise this, so you're aware.

Update 3/20/2019: I have updated my rating from 2 stars to 4. This is because Sunny Health and Fitness replaced my bike! In all sincerity, it’s some of the best customer service I’ve experienced. I can only recall receiving such service one other time, so it was stand-out. When I called their service line, an actual person answered instead of an automated system. It actually caught me off guard. They directed me to fill out a warranty form online even though I was likely out of warranty. I did so with little expectation that anything would happen, but figured at least I’d try. Much to my surprise, I heard back from them within a couple of days, they reviewed my submission and replaced the bike. It was more than I expected since I didn’t discover the structural defect until well after the warranty expired. I’m only on my second ride since receiving the replacement bike. I’ll leave my original review below and update it as I get more time on the new bike.Update 5/4/2019: I'm writing what I hope will be my final review on this product after receiving my replacement bike in March this year. I've had some time now to put the replacement bike through it's paces and to get a good feel for it's strengths and weaknesses. The first thing I checked, upon putting it together, was whether the frame was level this time. I literally took a level to almost every part of the bike, and this one was true. That was a relief after my last experience. Also, I've no longer been experiencing the back pain or knee pain caused by the previous bike with the crooked seat post tube on the frame.That said, I'm sticking with the four stars, because the rest of my quibbles still apply - except the part about the crooked seat post, obviously. You can read about what I liked and what I didn't like in my original review below. Despite my rather lengthy list of minor quibbles, it's still a nice bike for the price and I don't regret getting it.Summary: It's a good bike, and I like it. I plan to hang onto it and continue to use it as an indoor training bike during the bad weather months, or when I just don't have time for road rides. There's something immensely convenient about just hopping onto a bike in your own home, but not nearly as enjoyable as a road ride, of course. If you want a really inexpensive but very capable fitness bike, this is a great option. If you want something that's quiet (and has a water bottle holder!), you should probably expect to spend a little more money and go for a belt-driven model with magnetic resistance. I might do that someday - we'll see.Speaking of which, in the original review below I mentioned that I would probably not consider a Sunny Health and Fitness bike again due to the quality issues with the first bike. Well, after my great customer service experience and receiving a solid replacement bike, that has all changed. If the time comes for me to consider a new fitness bike, Sunny with be at the top of my list. They didn't have to replace my bike since it wasn't under warranty anymore. I should have noticed the issue earlier on, but I didn't because I used it so little initially. It seems that there are very few companies anymore that will stand by their products the way Sunny did with theirs. As a consumer, I appreciate that very much.*************************************************Original review (make sure to read the updates and summary too)...I bought this bike after undergoing a pretty significant surgery back in 2016. I'm an avid cyclist and wanted a machine that could at least help me accomplish some minor workouts during my recovery. Since my original intent was for a temporary solution, I didn't want to spend a lot of money. This bike seemed to be the perfect solution based on the reviews.When I got the bike, I was genuinely amazed at the build quality for the price. If you're old enough to remember those exercise bikes from the 80s that were completely flimsy and had a weird friction wheel adjustment that yielded an awkward pedal stroke as you added resistance...well, this bike is the complete opposite. It's heavy, solid, and has an extremely smooth and realistic ride quality. The 40 lb flywheel is great, probably contributing to the ride smoothness and quality. Assembly was incredibly easy, and the fit and finish (at least initially) appeared to be quite good. There were no scratches in the paint and the joint welds and build materials were solid. It also just looks nice with the chrome finish on the flywheel and the nice paint job. I was really happy with the bike.My only quibbles, until recently, were minor.- First, it’s noisy. I expected this based on the reviews, and it wasn't an issue for me since I use it in the basement away from the rest of the house. I’d prefer it to be quieter, of course, but I can live with a little noise for the price. If you’re in a shared living space or have sleeping kids nearby, the noise might be more of an issue for you.- Next, there’s no water bottle cage on the frame or cradle on the handle. I have to keep a TV tray next to the bike to hold my bottle. Again, not a deal-breaker, but it seems like a bit of an oversight for a piece of fitness equipment.- The handlebars and seat post are bit wobbly, even when fully tightened. But, it’s not a terrible wobble and I got used to it pretty quickly.- Next, the tension settings are inconsistent because the felt pads will wear or come out of adjustment when the brake is applied. Because of this, it’s harder to find consistent gearing/resistance when you’re trying to follow along with a fitness video. Installing a cadence meter and bike computer helped me with that to a degree.- In order to do chain maintenance, there are quite a few screws that need to be removed on the chain guard. It seems more time consuming that it needs to be, but the chain is soundly protected.- My biggest annoyance is the seat attachment. I replaced the factory seat with something nearly identical to my road bike saddle, but such a task was not as easy as it should be. It’s hard to explain, but the short story is that there are a lot of moving parts when attaching the seat compared with a standard bike. So, trying to fix the seat wobble or fine-adjust my saddle position was more cumbersome and eventually resulted in a stripped bolt. That should be easy enough to replace at the hardware store, but it’s an annoyance if you like to quickly fine-adjust your saddle orientation. I really have nothing good to say about the way the seat attaches to the bike, especially compared with road or mountain bike seat attachments, which are far easier.So, by now you’re probably wondering why I gave this bike two stars instead of three, four, or even five. Well, I've recently renewed my use of this bike as a trainer due to a tighter schedule and bad winter weather conditions. However, as I bumped up the intensity of my training, I hurt my back while riding my bike and was trying to figure out why. As I looked at the bike, I realized that while the bike itself was level, my seat was at an angle to one side of the bike. It wasn't just the seat itself, it was the entire post assembly. In order to level the seat, I had to raise the entire right side of the bike about a half inch by adjusting the bike’s foot pads. So, now the seat is level but the rest of the bike is at an awkward angle – a half-inch angle! This orientation has taken the strain off of my back, but it is now bothering my knee since the pedals are also at an angle (along with the handlebars).Regrettably, after looking at the Sunny Health and Fitness website, my bike is no longer under warranty, so there’s probably little, if anything, I can do about it. I did open an online claim anyway, in the off chance that the company might do something. But, I’m not holding my breath. In the meantime, I’ll be looking for a different training bike option, but it probably won’t be a Sunny Health and Fitness bike. My experience may be a fluke, based on all the other positive reviews, but I don’t know that I’m willing to take the chance on another at this point. Had it not been for this issue, which is very significant since I've had quite a bit of pain and several trips to the chiropractor, I would have been willing to give the bike a much better review since I otherwise genuinely like it.

I paid £155 for mine… and it was the 3rd bike I bought off Amazon in a week, after the two previous ones went back because I didn’t like them.This one was far and away the better one. And the build quality of it was way more attractive than one I paid £280.00 for, in fact I feel this bike is worth about £400 if I was to compare it to what I got for my money on the previous two bikes. (Only one very very minor gripe, more on that at the end 😄)What I loved about this bike was the ride position was fantastic and really well thought out from an ergonomic standpoint, which just makes the ride so much more comfortable.It looks like a much more expensive bike due to the good build quality, and no cheap looking bits or anything. There’s no computer but then that’s not a bad thing because they often look like cheap tat with no useful metrics unless it’s a really high end one. So I really didn’t mind that,It’s chain drive, which actually generates a super cool tactile feel. I personally love the little vibrations under my feet that gives the sensation of riding a bike. I find belt drive to be too perfectly smooth and it’s a horrible fake feel and nothing exciting about it. But having said that some people love belts and pay more for them, but I find chain much more appealing. It will make a very slight rattling noise but that is very quiet and it’s not noisy. I ride with music so I don’t even hear it, but with no music you might find it a little annoying.And lastly a good reasonably heavy flywheel - very good feel, I found, @ 18kg, (one bike I tried and returned was slightly more than needed at 20kg and the other one which was 8kg seemed pathetically too little) but this one @ 40lbs gives a good workout and generates lots of momentum. It’s also got quite a small footprint so it’s not too difficult to move around.The minor gripe, (the thing that wasn’t absolutely fantastic about the build quality, and I think this maybe why it’s so cheap) is that the handlebar tube on mine was a little too tight, I actually greased mine up with a little olive oil to ease the sliding of it as it was tight.But this is the really strange thing, because everything else about the build quality is what I would expect from a bike priced at maybe even £400.Fortunately they had the foresight to fit this thing with an emergency brake, incase you’re working out in the living room and then all of a sudden your lunatic dog randomly tries to jump out in front of you, whilst cycling a bit too fast.

The Sunny Health & Fitness SF-B123033 spin bike worked great on my first ride, smooth and quiet. But the seat started shifting, and I discovered a bolt underneath was missing or broken. I contacted Sunny right away and was initially told I’d need to pay $50 USD for shipping, even though the issue was present from the start.After some back-and-forth, they sent the replacement part at no charge, which I appreciated. The bike is solid and rides well, but the support process was frustrating at first. I’m glad it was resolved fairly in the end.Canadian buyers should be aware that warranty and shipping policies may differ, but persistence helped in my case.Thank you Sunny Health ❤️ Happy Spinning everyone 🚴

Perhaps I didn't have super high expectations but the reviews were good, it was stated to be suitable for someone my height (6'2") and weight (225 lbs.) and the price seemed too good to pass up so I bought it in preparation for next Winter.From the moment I touched it, my expectations have been exceeded. The box is a combination of heavy (115 lbs.) and large rectangular box which made it difficult for a single person to carry. I recommend that you be prepared to have two healthy people available to carry this to it's expected resting place from where it is delivered. I work out and believe I am fairly strong but this package humbled me.I set it up in two spurts of approximately 15-20 minutes each. Total time is probably around 30 minutes. Each and every part on this bike, including the "travel" blocks which can be thrown away, are extremely heavy and well built. Solid steel (I assume) and painted if not stainless steel. If this were a real bike you would not make it very far. But once I got it set up and hopped on, it took a few minutes to make the appropriate adjustments to get the seat and handle bars to where they felt comfortable. I was a bit disappointed that you have to take the adjustment knobs completely out in order to make the adjustments but each and every knob and adjustment piece are very heavy and sturdy. Even the seat and handlebars seem extremely well built and of high quality. The fly wheel is heavy and looks pretty flashy. There is not a single item on the bike that seems like a corner was cut. Even the instructions use full sized pages, are clear and were easy to follow. The only item that I wasn't quite sure about were the pedal nuts that came attached to the pedals and not on the base of the bike like the picture seemed to suggest. This bike seems NOTHING like any other Chinese manufactured item I have ever purchased and I seem to buy quite a few things from overseas. Mostly electronics though and in that space what could be metal is typically plastic. Not the case with this bike. What could be plastic seems to be metal.I test rode the bike for ~5 minutes or so with the tension as high as possible where I could still get to a good speed and I was able to get heated up to the point where I was about to start sweating. There were a few small noises that prevented the bike from being near silent but everything seemed to be installed correctly (both what I assembled and what came pre-assembled).In addition to the next Winter season, I plan to use this bike most days while I'm on conference calls via Teams, Zoom, WebEx, etc.. At some point, I plan to follow a few hacks from another review to add a tachometer/odometer and a few other bells and whistles.I HIGHLY recommend this bike if you've been thinking about getting a well built but basic stationary bike and you're able to get it at a good price. At least a price that is good for you.
