    • It works great... until you need to replace parts!
Style: Magnetic
TL;DR: Unless you love a good DIY project you might want to order a better quality product. **Second edit - Trying to get this bike apart has been the bane of my existence. It's involved two of us using a pipe wrench, as this thing is so tightly wedged together nothing budges. It took full hours of trying to get the crank off. Now, the axel won't budge. The videos they send you show all the parts sliding out with ease. It took a total of six days - approximately 8 hours total - to get the bike apart and reassembled. Since some of the parts were absolutely destroyed in the process I spent my own money at a bike shop to get this thing cobbled back together. The good news is the fix worked, and now I know exactly how much force this bike is going to take to get it apart. As I mentioned below, this bike was great. Unfortunately, the way it comes from the factory this thing is practically welded together and it will take you HOURS to make that first repair. Hopefully, since we put it back together ourselves, the next repair won't be as difficult. ***Edit after only 3 months: This bike developed a very, VERY terrible "clunking" sound when the pedal was in a particular position. After doing some googling, it seemed a bearing needed replaced. Sunny confirmed this and let me know they'd send the bearings. However, I went ahead and ordered the bearing and a crank puller myself. Despite customer service telling me what size puller to get, the size of the crank bolts, and the bearing model, it has quickly turned into a nightmare. The nuts stripped when trying to remove them (both crank nuts), the size crank puller they told me to get had to be man-handled with a PIPE WRENCH to even get them to thread, and the stripped nuts now have to be replaced as well. A 20-minute job turned into a four hour ordeal and my bike is now in pieces. I have had the bike for less than three months and it has less than 700 miles on it. ***Original review: I am the kind of person who researches the heck out of something before I buy it. TL;DR this bike is perfect for someone getting into cycling who is under 265 lb (the weight limit) and doesn't mind a machine that doesn't make the adjustments for them. Longer review below: I bought this bike to use with iFit. I have a treadmill from a compatible iFit brand and the customer service and quality of the machine made me dread buying a bike from them. I love the features of iFit and I love that it offers so much more than the traditional studio class, so I knew I would have to buy a bike that was incompatible. I also wanted to avoid buying another brand, like Bowflex or Peloton or any of the other name brand bikes, mostly because I don't want ANOTHER fitness app. I'm happy with mine and honestly don't want to pay for a gym membership and two fitness apps every single month. After a lot of research and looking at several other brands, I came to this one. What drew me is what probably drew you - the person who "hacked" their bike into a Peloton. I knew I personally wanted a silent, magnetic bike with interchangeable parts - like pedals and seat. So far I have not changed those yet, but I plan to in the future. Things other people will say in negative reviews you might worry about (like I did): "This seat is uncomfortable" - that's biking y'all. Buy yourself a pair of $10 biking shorts on here when you buy this bike. After a few weeks you won't need them anymore. This seat for a spin bike is a cushy, comfortable seat that is incredible padded. "It makes a knocking noise when I pedal" - sure does... when your pedal cage fastener hits the pedal it will indeed make a knocking noise. Move the metal fastener and it won't do it again. "It's unstable when I stand up" - There are four adjustable feet on this thing. Make some micro adjustments and it will be still and sturdy. "The pedals don't assemble right/fall off/strip when I try to use them" - Sunny has a 45 second video to demonstrate how to put these pedals on - just google Sunny Bike Pedal Installation and you'll find it. "The seat won't tighten and falls everywhere" - It honestly will with the tools provided. You're gonna have to adjust it a few times the first few times you ride the bike. So, if you're still reading I assembled this bike by myself in approximately half an hour. I watched the above-mentioned video to install the pedals because I was terrified I would screw them up because the directions are SO DANG SPECIFIC so you don't install them wrong. Thirty minutes and I was on and riding. All the little things above I experienced myself with the bike... and they were all super easy fixes. I had to make a few adjustments the first few times I rode, including with the seat several times before I got it locked in just right. Using this with iFit has been super simple once I figured out the whole RPM/RPE thing and the simple computer console on this bike let's me do everything I could on a fancier bike. For those who want to use iFit, when you use incompatible equipment you'll see a resistance level broadcast on your screen. From what I've seen so far it only goes to 5. I turn the resistance wheel two full times to get it at the "level" broadcast on the screen. I start at zero and in the warm up cycle I turn it two full times to be at a 1 level. Two more full turns for each level of resistance up to 5. If it looks like we're going up a hill, I do one full turn to add some more and move it back down when it levels out. I've found with this little system of mine I can keep the RPMs they call for while still getting a workout. I've ridden over 120 miles on this bike in the 3 weeks since I've bought it and I couldn't be happier with this purchase. I manually upload my ride to keep track of the mileage weekly on Strava, but honestly the Wahoo Cadence Sensor may be my next purchase since I love this bike so much. It's absolutely silent, easy to assemble, solid, and simple to use. If you're looking for a cheap beginner's alternative to an expensive "smart bike" and app service, this is absolutely it. You won't be disappointed with this bike. ... show more

    • Excellent Peloton DIY
Style: Magnetic
Review Image by P. Schrupp P. Schrupp
Review Image by P. Schrupp P. Schrupp
My local gym was closed for months, was able to open for a short time, and recently closed down again. So during this COVID time, I need something that I can do at home. I live in MN, and exercise outside in the winter is not an option for me. I have not taken a spin class for 15 years, but a spin bike is more in my budget than a treadmill. Plus, treadmills need a lot more space and when they break down the fixing can be pricey. So, spin bike, here we go! Like other reviewers, I wanted a Peloton, however, let's be real if you are looking at this bike, spending $2500 on a bike plus monthly subscription of $40 is probably not in your budget either! You are benefiting from my research! As I looked, there is pretty much a bike for everyone's budget. I am keeping my gym membership, so I did not want to spend an exorbitant amount. I was going to get one with a belt and 45-pound flywheel, but then I stumbled upon this one. The availability, magnetic wheel, price, super fast Amazon Prime shipping, the iPad shelf, and the "computer" are what sold me. I have seen a few reviews with damaged boxes, mine was fine, and I think the great packing job would totally protect the bike. It took about 30 minutes to assemble...thank you for your help, Husband! Once put together, it was easy for him to carry it to the next room (probs about 80 pounds). I have the bike in a carpeted room with a plastic chair mat under it. I will not be rolling it around, but I think it would be pretty easy. I am 140 pounds and am 5'6". The bike is sturdy, I feel totally safe when I am up out of the saddle. Speaking of saddles, I replaced the giant seat right away. I got this one: https://www.amazon.com/gp/product/B0845PGYYZ/ref=ppx_yo_dt_b_asin_title_o05_s02?ie=UTF8&psc=1 I may upgrade again or add a cushion, but I did not want to spend too much without being able to try it out. I have to (or should I say my backside has to) get used to spinning again! I knew the seat the bike comes with would be much too large for my preference. The size I got is more in line with the size of the seat on my road bike. I also upgraded the pedals. I want to use my road bike shoes (way more productive), so I got these pedals in the event my husband gets an inkling to go for a ride. I can clip in on one side, and he can use the cages on the other side. A nice compromise. https://www.amazon.com/gp/product/B081BDDGJ8/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 If you want to use your road bike shoes exclusively, I'd recommend these: https://www.amazon.com/gp/product/B000KC3Y0G/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 The bike is silent! I mean silent! I'm pretty sure the magnetic resistance attributes to how quiet it is and, there should not really be any maintenance. The iPad holder and the stat reader are great. I only look at the rpm's (same as Peloton's "cadence") when I ride. The tracker goes between time, speed, distance, calorie, odometer, RPM, and Pulse. It is important to know that this device will not give you the most accurate readings of your performance because it has no way of knowing your body size and conditioning level. So expect them to be relatively generic. I use my own heart rate monitor and I still have to get an iPhone holder that I can attach to the bike, so I can see my heart rate app on my phone easier. I bought the Peloton app for $12/month (I did the 30-day free trial first) and watch it on my iPad. The iPad is quite secure in the holder. If you have a ROKU, you can watch the Peloton classes on your tv! The bike does not come with weight holders, and it is kind of annoying that you cannot buy the ones Sunny puts on the higher price point bikes a la carte. So, I am going to pay about $45 to get them on Etsy. I think the reason the other Sunny bikes are more money is that you would not have to "DIY" them. They come with weight holders and such.... I am COMPLETELY satisfied with my purchase! I think spinning would suck without the Peleton app (or another app or YouTube videos)...I mean it is pretty boring to just sit and pedal. Ride on, people. EDIT: A few people asked for some pics of the seat installation (I changed out the seat), and the tablet holder. ... show more
