    • Pros Outweigh the Cons
Style: Pro II
25 October 2021 UPDATE (11 months of ownership) Just wanted to check in and report how things are going. In short, we are still very happy with our purchase. We regularly use the bike (me a bit less since I have been back going to a local gym, but my wife and our youngest son use the bike about 3-4 times per week; I use it 1-2 times per week). My original wordy review is below, but here is an updated summary: Pros: Well built, particularly for the price. Perhaps not as cosmetically polished as Peloton or more pricey bikes, but still sharp looking and durable. Runs smoothly. Magnetic resistance works nicely. No "clicking." Bike still looks and operates as new, even after almost a year of regular use. Neutral: I was a bit critical of the display initially, as others have been. In actuality, it has been fine. It does the job. Could be better, of course, but it's good enough. Cons: I list them in my initial review below, but for me they have not been an issue. My wife and son do not adjust the handlebars (because adjusting the handlebars is a bit of a pain), but they do adjust the seat (adjusting the seat is easy and convenient). The heart rate monitor remains useless (it should operate correctly and it is disappointing it does not, but it really is not something which has affected my enjoyment of the bike). All in all, we enjoy the bike and I still love riding it while I blast my music videos. ______________________ 28 April 2021 UPDATE (a few days shy of 6 months of ownership). I have added a few updates/edits to my original review below. Long story short, yes, there are cons, but I remain happy with my purchase and continue to use the bike regularly. Generally very well built, with a few ergonomic and practical shortcomings which are relatively minor for me, but I wanted to point out for others. Sunny can make quick fixes of these on their next version or for another model. For me, though, all things considering, I am still glad I purchased this bike. We have owned the Sunny Evolution Pro II for approx. 6 months. I use it about 4 times per week, my wife uses it about 1-2 times per week, and when our oldest is home from college he uses it 1-2 times per week. When I ride I usually go for 30-60 minutes depending upon my workout. I often do hill climbs to loud blaring music videos (i.e., standing and not sitting on the bike seat). We replaced a three year old lesser expensive Sunny Health and Fitness bike to purchase this one. We all have different expectations and priorities and what might seem insignificant to some is bothersome to others, but here we go………….. The quick and dirty: Pros: 1. purchased from and sold by Amazon and service, as always, was excellent; 2. arrived safely; 3. easy to assemble; 4. generally very solid construction; 5. reasonably comfortable (for a spin bike); and, 6. smooth magnetic resistance operation. Cons: 1. although arrived safely, given past reviews of various Sunny bikes could have been packed a bit more securely; 2. heart rate monitor is wildly inaccurate; 3. display feels somewhat cheap—it is large and legible in good light, but hard to read if the lights are low or you are standing (i.e., while doing hill climbs); 4. seat and handlebars should be more adjustable; 5. tablet/phone/book holder is a decent nice size, but the “lip” holding your tablet, phone, or book is too small in depth; and, 6. water bottle and dumbbell holders are not conveniently located. A bit more detail: My details: I am a middle aged former competitive powerlifter (5’9” guy, somewhat stocky muscular build) and have been training martial arts for about 25 years, lately Brazilian Jiu Jitsu. I still lift heavily, but not quite so much as in my younger more nimble days. I have been performing much more cardio and boot camp stuff over the last several years. A few years ago we thought about getting a Peloton bike (well I did, perhaps not my wife), but while I like using a spin bike going to spin class is generally not my thing. We have a pretty good gym setup in our basement and I wanted to add a spin bike I could use while watching and blasting music videos. A few years ago we purchased an inexpensive Sunny bike (less than $300) to "test the waters" before making a more substantial purchase. It is a nice no frills bike—well constructed, although not the most comfortable and the resistance went from easy to very difficult too quickly given its simple brake pad resistance design (some bikes with brake pads have more travel between resistance, but that one did not). I used the bike a lot, particularly over the past pandemic year, and it was time to look for a replacement. Decision making process: I considered a Peloton again, but rejected it for the same reason: I like spin classes occasionally, but I prefer to blast my own music and I am experienced enough with exercise that I can design my own workouts. I also felt we could purchase a high quality spin bike for much less money. And, I can always choose to use the Peloton app. I looked at a number of models by Sole, Revmaster (from Greg Lemond), BodySolid (the ESB250 looks similar to this Sunny bike, albeit the ESB250 is not magnetic, and we own a couple of commercial quality pieces of equipment from BodySolid: really good stuff BTW for the money), and Life Fitness, among many brands, and almost pulled the trigger on one of these bikes. Just my opinion, but I do not recommend Proform, NordicTrack, or Bowflex. I had been looking at this Sunny bike for a while, however, and felt that despite some of the reviews for this bike and the original Evolution Pro, and various other Sunny bikes, purchasing from Amazon meant I could feel safe buying the bike if a problem arose. We purchase a lot from Amazon and their service has always been outstanding. And, virtually all of the spin bike brands have mixed reviews, even for very expensive models. At some point I also was reading too many reviews: the paralysis of analysis. So we made the decision to purchase this bike. Shipping and arrival: The bike arrived quickly and safely. The box was a little torn from the plastic fasteners surrounding the box (but not too badly) and the bike parts should have been fully surrounded by Styrofoam or similar padding in case of a box puncture, but in the end the bike arrived undamaged. Instructions and assembly: The instructions are somewhat generic and could be clearer, but after years of putting together lots of exercise equipment and furniture (and toys for our children) I really did not need the instructions. The bike actually arrives largely assembled. There is not too much more you have to do. Unpacking everything takes about as long as actually assembling the bike. Display: The display feels “plasticky” and could be attached more securely to the bike. It is not backlit. The numbers are large and legible, but if you like to turn the lights down or are not in a well lit room you may have trouble reading the numbers. Depending upon how tall you are and perhaps how close/far you have placed the handlebars, and given that the display is attached on an angle, you may have some difficulty reading the display when you stand such as when you are doing “hill climbs.” I may be missing something and might figure out a way around this, but it would be helpful for the monitor to show cadence, time and speed on the same display (there are two display modes that you can toggle through—speed, distance, and time on one page and cadence, calories, and heartrate on the other). I will be contacting Sunny customer service to see if there is a workaround to the display issue and will update my review after I hear back. UPDATE: Sunny customer service got back to me promptly and let me know that the display format cannot be changed. It's fine. I'd prefer a different layout, but it works sufficiently for me. Another thing I have noticed is that the display is not firmly attached to the bike. It hooks on, but is not held firmly in place. It will make replacing the battery easier, but it would be nice if it did not move around. A bit of a nit pick. It is not a big deal. Heart rate monitor: The heart rate monitor is way off base—often by 30-50 beats (you read that right). I did not expect it to match a chest strap heart rate monitor or an Apple watch, but it is essentially useless. I have differed my hand placement with the heart rate sensors, but this does not seem to change the accuracy. UPDATE: still wholly inaccurate. No worries. I know my heart is still beating. For an accurate heartrate, a chest strap or smartwatch is the better choice. Adjustability: The adjustability of the seat and the handlebars should be increased by a couple of inches for each part (e.g., the seat and the handlebars). My earlier and less expense Sunny bike was a little more adjustable. By being less adjustable you may find yourself reaching or bending over a bit to hold the handlebars. My sense is that someone who is much shorter than I and has shorter arms may experience this. My wife (5' 5") is able to ride the bike, but she does not really like spin bikes to begin with--she prefers to run. So, she uses the bike to mix things up. Our oldest son is 6 feet tall and he likes using the bike. Although stocky and having a lifter’s build I do not have short arms like many competitive lifters and yet I still find myself reaching over a bit to hold the handlebars when I am sitting upright. When I do lean forward on purpose, for sprints for example, I find the handlebars reasonably comfortable and provide a nice variety of grip options (although there is no place specially shaped to rest your elbows if you like to do that). Also, adjusting the seat is easy, but adjusting the handlebars is a bit of an effort. So, repeatedly adjusting the handlebars between different users can be a bit of a pain. UPDATE: adjusting the handlebars remains a pain. There is a knob on top that one loosens or tightens, but the "bolt" under the handlebars into which the knob screws really needs to be held in place with a wrench when turning the knob. It is a big bolt, but too small to really grab onto and hold while turning the knob. And, I am a pretty strong guy. My wife leaves the handlebars "as is." If you have to adjust them regularly it might be annoying (as noted above, though, the seat is easily adjustable). Seat: The seat that comes with the bike is comfortable for me. Spin bike seats are notorious for being uncomfortable. The seat is among the better ones I have sat on. Everyone’s tuchus is different. So, what is comfortable for one person may not be for another. Operation: The magnetic resistance is smooth and operates well. It takes about 6 full turns to go from no resistance to the maximum resistance. Our other Sunny bike went from easy to max in less than a half turn. Clicking: One issue that seems to arise in the Sunny reviews is the dreaded “clicking.” My first Sunny bike did not click and, at least so far, this one does not either. Except…there is a click from the adjustable shoe strap where you place your foot. If you do not tighten the strap the excess length of the strap does make a repetitive clicking noise as you ride--but that is easily fixed through adjusting the strap. And, in any event with music videos blasting dance music I am in the zone and do not hear anything. If there is some internal mechanical clicking issue for some bikes, I have never experienced it. UPDATE: still no clicking. There is sound when riding. So, the wheel perhaps is not silent, but it is quiet and smooth. Much quieter than a bike with a brake pad. Bottle and weight holders: I know another reviewer mentioned the opposite, but I find the water bottle holder too far out of the way to easily reach. I do not use hand weights, but it would be better to make the hand weight holder more accessible, too (place higher on the frame or behind and under the seat, as other bike models do, such as the Peloton). Overall: We paid $850 for the bike. This I think is on the low end of an “upper tier bike.” Having said that, the heart rate monitor should work, the bike should be more adjustable—there does not appear to be anything mechanically preventing Sunny from adding more adjustability. And, the monitor should be backlit and attached more securely. A backlit display may mean going through batteries more quickly (it operates on battery power) or accessing the bike wheel for generating what probably would be a low power requirement to run and light up the display. The bike does look sharp—I think better in person than in pictures on a computer screen or tablet/phone. For me the solid construction and smooth magnetic resistance are what is most important. I am disappointed by the inaccurate heart rate monitor and the display could be better, as could be the adjustability of the bike, but for the price and the pros vs cons I am satisfied. The "cons" do not really affect my enjoyment of the bike--but they are annoying given that this is not a "econo" bike. It's not a high end one, either, but seemingly easy fixes could eliminate these issues (at least re adjustability and having the display show speed, distance, and cadence--and even time--on a single screen). UPDATE: I have found the bike to be a very good value. I work out pretty hard (although I do not abuse our workout equipment). I do not know this, of course, but I almost get the sense this bike and other Sunny bikes are designed on a computer screen with no prototype. And, I do not get the sense that Sunny is a company managed primarily by people who workout (at least with Sunny equipment). Thus, certain ergonomics are not obvious until people actually start to use the bike. Having said that, this bike (and our prior inexpensive Sunny one) is well built. Hundreds of dollars to a thousand dollars of additional cost (and by that I mean NOT including electronics or "bells and whistles") will get you better machining and likely improved ergonomics, and perhaps a better display, but I have found this bike to be a really good value (6 months in). It's frame is built extremely well. In the end, I am grinding out workouts in our basement, with music videos blasting, and that is what is most important, right? ... show more

    • I really like this bike and so far seems durable, but get a proper saddle!
Style: Pro
Review Image by Anon Anon

I ordered this on March 21, 2022 My PCP told me I needed to start exercising in a way that was better for my knees, so cycling it was. But I live out in the county and it is primarily gravel roads, so I ended up deciding to just get a stationary bike first. I'm a large man, 250lbs and 6ft6" tall so it was a lengthy search finding something in my budget that would work for me. My legs were still a little too long for this bike but it was close enough I could still use it without feeling overly cramped. Assembly was simple and it feels very robust, I was actually impressed by the weight and rigidity of the materials. I get zero flex or wobble after properly adjusting the feet heights on my tile floor. I had doubts about the durability of the belt drive system, but so far I haven't had any issues and it's definitely much more quiet than some older chain drive stationary bikes I remember riding in the past. There were a couple things that were a problem though. The bottle holder placement is very awkward while riding. You can't exactly coast on these like a regular bike so grabbing a water bottle while peddling is impossible for me, mostly due to my height. I really wish these had other optional mounting heights and locations. I'll likely drill higher holes and install some rivnuts to move it up. But for now I've just been stopping to take a drink. And the other issue was the seat. I absolutely HATED the seat on this thing. It did not fit my anatomy at all and was way too squishy in all the wrong places. I now have a properly sized Brooks bike saddle installed and it makes a HUGE difference. Soooooo much more comfortable! so much so that I can ride this thing for hours without my butt hurting. And The seat mounting bracket can be removed from the original seat and be transferred over to the new saddle. Was a very easy process. Also, based on the advice from a friend that is an experienced cyclist I determined where to better position the seat for my long legs and increase comfort even further. But to do this I had to modify the mounting bracket. Even after adjusting everything to the maximum position I still couldn't get a proper leg extension. But after the modification it is absolutely fantastic and due to the build quality I don't expect to need a replacement for many years. With the seat so far back I did occasionally rub the riser post with my thigh, but it's nothing painful, was just barely brushing up against it. But after getting some proper cycling bibs it never happens anymore due to the compression at the thing. So if you're slightly too tall for the bike, you can drill a hole in the seat post plate and flip the plate around and then bolt it on to get more length. BUT it's not easily adjustable now, so if you have multiple riders In the house I don't recommend this. ... show more

    • Great Bike Less than Steller Support
Style: Pro
I have waited over 13 months to make this review. I don't think I will be breaking new ground with my review but I thought it might be helpful for others looking to purchase this bike. My initial experience with this bike and Sunny support was pretty negative. I had a really really simple issue... My right crank arm was not seated properly and was causing the pedal to wobble during my rides. I would tighten the nut and it would loosen again mid-ride. Support is strictly email, so I spent about 6 to 8 weeks going back and forth with emails with pictures of the bike and videos they provided to help troubleshoot the issue all of which was way overkill for the actual problem. They finally sent me a tool to remove the crank arm and a replacement part for the issue they misdiagnosed. I finally reseated the crank arm and the bike has been smooth as butta ever since. I occasionally have to tighten the bolts but that is every month or so, not mid-ride. So for the last 9 months the bike has met or exceeded all of my expectations. As others have mentioned, it offers a smooth, quiet ride and the heavy flywheel really offers some nice resistance and I've really toned and strengthened my legs in the last year. For the price, I would definitely buy this bike again, no question about it. Just know going in how their support system operates and it would be helpful if you or someone you know has bicycle mechanic experience. ... show more
