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

Great quality bike, stable and silent.

After I stopped going outside due to COVID, I've originally purchased a spin bike that has a hard sponge form brake pad. Which was making annoying squeaky noise, so I returned and bought one with a leather padded brake pad. Then the padded leather just fell off after a month or so, and again I had to return it. I sort of realized that those break pads wont really last a long time no matter what material is used, so I purchased this one. The magnetic is really strong. At a maximum setting, I can actually stand on the bike and the resistance is really hard, which is great. One thing is that, I've gained quite a lot of weight since COVID, and the seat is sort of making a squeaky noise a bit if my body moves a lot on the bike. It is solid enough so I don't feel unsafe but It is not like professional level bikes you would see at the gym. The thing is, I actually look for one of those pro-level bike and they were over 3k USD. So, I am quite happy with this purchase. Good value for the pice I'd say.

After using it 5 times only, the seat was damaged.

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.

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.

easy to put together,

its vary smooth

easy gear change

light flywheel

I will update this and do a full review in the future

Muy buen producto, y mejor compra

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!
