Review: Smooth, quiet and sturdy. - 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 desertcart 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.
Review: Excellent bike, not without issues. - 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.

### ⭐⭐⭐⭐⭐ BUY THIS BIKE!!! IT'S PERFECT. GREAT IF YOU'RE TALL. THE BEST RESISTANCE MECHANISM.
*by E***O on February 5, 2021*

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.
