Sunny Health & Fitness Exercise Bike w/Pulse Sensors & Adjustable Cushion Seat, Home Cardio Training Machine for Adults/Seniors' Indoor Cycling Workout, Optional Compact Foldable or Electro-Magnetic

I have NEVER assembled anything in my life, I usually get someone to do it bc I don’t have the patience but I decided to give it a go and I’m so proud of myself. The instructions were exactly correct and detailed enough to understand and if I didn’t take breaks bc I was cooking I probably would’ve been done in 45 minutes. At first it was intimidating but just follow the steps exactly as they are and you’ll be fine. I would’ve given it 5+ stars but I cannot figure out how to setup the computer display, I wish it came with the same type of instructions. I’m still very happy with it, I was replacing one I had for 10+ yrs which finally broke, it was a Weslo which at the time was like having a Peloton. Well this one works so far beyond my expectations and I love that it calculates the calories and the bpm sensor is surprisingly accurate (I checked my pulse on my own a few times to see if it was the same), and I love that it has the heart rate zones which is a great reminder and keeps you on top of your game. Also it is sooo quiet! I love it, with me last bike I had to always turn up the tv to max while I biked and watched my shows or a movie but now it’s not an issue, and the seat slider adjustment lets you really get a good fit, and the stride is so move and fantastic, I also bike outside so my legs are pretty strong and I feel I can get a good workout whether pacing or really challenging myself between the 5 and 8 levels, 8 being the max. One thing I cannot do is get it hard enough to actually stand on it and pedal but that’s totally fine, I have my outdoor bicycle and hills in the park. Also the seat is great and I have a big bum, I usually struggle with comfort bc of it, and the material like a non-slip which does wonders bc even my weslo if I was using certain pants I would sometimes slide. I’m very happy, I think I’m going to contact the company about the display setup (date/time/profiles), other than that it’s very sturdy and a really great buy. Well done

I use the SF-B2883 for daily exercise, since the winter is snowy in New York City and the gym I usually use is closed due to Covid. I would have preferred to buy a recumbent bike since that's what I'm used to using at the gym, but the compact footprint of the B2883 is much better suited to apartment living. I've been using the bike for just a month so far and I am very pleased with my purchase.I was concerned that the quality of the bike might be low because it was relatively inexpensive. But that was not the case. It's solidly constructed and works well. And, before I forget to mention it, it was easy to assemble. Most of the bolts and other hardware come already affixed to the area of the bike to which they will be permanently fastened. This saves you a lot of time--you don't have to look through a pile of hardware each step of the way.The ride is consistently smooth and it's quiet thanks to the belt drive. The electromagnetic resistance works well (so far, I've only been using a singe intermediate resistance level). The console is not as sophisticated as those on commercial gym bikes, but it certainly has all the stuff I need. The bike is stable when I ride, and also when I get on and off.On the minus side, I find that the seat is not as comfortable as it should be. I may try to find a padded seat cover for it and see if that does the trick. Also, I wish that the handlebars were adjustable because, due to the relative positioning of the seat and handlebars, holding onto the handlebars forces your arms into a leaning position. One of my shoulders is arthritic and this leaning position aggravates it. Since I first wrote this review, I have beeb able to alleviate both these issues somewhat by re-adjusting the seat to a more forward position.So far, I'm very happy with my choice.

Background: I am a gym rat who has no gym to go to. My book, IMO, walking/jogging is a better calorie burning exercise than a bike (3 miles is like 30 miles in Cal burn), ...that is just my opinion...but it’s too hot out right now and unfortunately age is catching up to me. Elliptical would be best but space is limited and bike is a compromise during a time of shortage of at home cardio fitness equipment. Plus a high quality treadmill/elliptical is equal to one year at a high end gym. Let’s not get into Peloton.The good... this is a fairly inexpensive temporary solution that takes up a small amount of space. Wanted an upright over a spin/stationary cycle mainly because of the standing/full bent riding position and I don't like the noisy flywheel design.Putting together. Standard pain in the tush allen wrench self-assembly with some opportunity to use a power tool. 1.5+ hours and would be better if I had an allen wrench driver set or they made it a hex nut.3.5* = Product First impressions...mixed bag. Bottom parts are solid steel. Other parts (like handlebars, cup holder, and the main drive shaft are “aluminum feeling” and “tinny” like most of today's engineered products to cut costs. This is DEFINITELY not high end gym quality... but hopefully will get me through to the fall when you can walk without the humidity.2.5* the seat to handle bar is about an inch or 2 too far way. Adjusting seat closer helps but I used to have an old Reebok bike I gave away that was way more comfortable for arm positions. Adjusting seat forward seems to help2.0 to 2.5* onboard program unit. Cheap plastic with a place to put your phone/tablet. The computer is simple with no true manual mode, although each individual program can be adjusted. Only had a month + and yes the machine does seem to make noise when switching gears like other reviews have mentioned.3.5* seat. Pretty uncomfortable at first but after finding the sweet zone it’s not bad. 40 minutes is about the max with a couple minutes break but easily can do an hour plus a day. Gel seat cover might help.Durability is the big question mark. I believe it's rated 240 lbs because if you really press down on main handle bar assembly a strong or heavy person can snap it. Looks like something that will strip with time. Resistance changes seems a little sketchy and I bought the extended warranty just to be safeStarting out with 4* rating but should really be like 3.25 or 3.5.
