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.

The magnetic resistance on this unit is great, the assembly was very straightforward and the bike is pretty sturdy. There are 3 people in my family using this bike ranging from 5' 7" to 6' 0" and we all can easily adjust to a good riding position that is comfortable. Having rode a few "spin" style bikes this one may be slightly noisier than some models that would cost a good thousand more, but honestly it is a really quiet machine. This one feels just fine and will definitely challenge most people. Also the SPD and the cage are really cool to have combined on the pedal and very functional.

I don't know why some users left a few bad reviews for this item is unbelievably good for the price range! I am happy I came across Sunny sb-1709 before committing to the Schwinn IC4-8. Everything is comparable and lays on the same grass, but having the heart rate monitor pads on my Sunny is priceless And the aggressive downside handle oh may guud top top top

easy to put together, its vary smooth easy gear change light flywheel I will update this and do a full review in the future

I am so happy with the bike which was delivered today and is better than I had hoped. It’s sturdy and quiet with a great level to increase the difficulty level- so far extremely pleased I chose this one

Great quality bike, stable and silent.
