If you've had the BANGING issue with this bike, skip to the end for notes on my fix***********************************Initially I had looked at buying the Peloton bike because of their really great app but ultimately decided it was not worth the investment considering spinning was completely new to me. My intention was to use this bike in conjunction with the Peloton app ($12/mo). So far I am very satisfied with my purchase.Delivery - I paid just under $300 for the bike which included shipping. Which is really unbelievable in and of itself. I'm not sure how the UPS guy even got it up the stairs to our landing because the box weighed over 120 pounds. This bike is *very* sturdy. My first concern was that for $300 you would get a rickety piece of garbage. Not the case. Peloton charges $250 just for shipping.Assembly - honestly, the actual assembly part took about ten minutes. But it took 10 minutes to get the box into the basement, 15 minutes to unpack the box and unwrap all the parts and another 5 to sort of gather everything together. There are very few actual pieces, like I said, the bike is very sturdy when put together."Add ons" / changes - I made a few minor additions to the bike to improve the use.1 - Added a pair of Shimano SPD pedals ($35). These are fantastic pedals, I *highly* recommend them and they work great on this bike. Took only a few minutes to swap out. So far zero issues with the pedals. Please not if you have never used clip-in pedals before, you will need bike shoes with SPD cleats on them to use.https://www.amazon.com/gp/product/B003ZMDK5C2 - Simple ipad holder for the handlebars ($20). I have a beat up, cracked-up old ipad4 that I planned to use on the bike and this clip works perfectly.https://www.amazon.com/gp/product/B00D5YTO5K3 - Bike mat ($30) - perfect size, seems to work great so far. Its a mat, nothing fancy.https://www.amazon.com/gp/product/B001THTUAO4 - Wireless computer from spinning.com ($65) - I tried two of the Cateye models and just did not like how small they were and one I could not get to work with the spin bike. The spinning.com computers are made to work with their brand spin bikes but seems to work great with this model. Look I am not an engineer, I'm not going to guarantee that these are insanely accurate and are really only made for their brand bikes - but its worked fine so far. I was most interested in something that was wireless, would display time/cadence at the same time and that was easy to read.So I spent $150 or so on other options and am completely happy right now with my setup.***Notes on use with the Peloton app*** - As I said, I bought this bike specifically to use with the Peloton app. I am very impressed with the app so far. They have dozens of live classes every day or thousands of on demand ones. The app has a pretty simple filter that allows you to search/sort by class type, time, instructor etc. I wish there were a couple of minor tweaks - like letting you save your favorite rides into some kind of favorites menu - but so far I am very happy. The ipad version of the app is $12/month whereas if you have the Peleton bike they charge you $40/month. Even at that price, IMO, its worth it since I have been using it every day. Spin studios in the DC area can run upwards of $175-200/month for unlimited rides.***Notes on FIXES or things that might break*** - As has been noted in other reviews there seem to be a couple of quality control issues, both of which I ran into.1 - Squeaky resistance pad - Definitely happened to me over the first week. I used it every day and it seemed to get worse. I bought a $7 can of liquid graphite spray off Amazon and I gave it a few shots, it cleared right up. I could see just giving it a shot every couple weeks. Nothing major here, very easy fix.2 - That BANGING or knocking on every peddle stroke. - If you've had it, you know what I'm talking about. It sounds like the bike is broken and goes BANG BANG BANG on each peddle stroke. I emailed the company and they sent me a PDF with pictures about making some adjustments to the belt with the two adjustment screws on the front. I spent @ 20 minutes screwing around with it and eventually it did stop. It was a pain in the neck and very annoying to have to deal with but it did finally stop.- Take the belt cover off - screws on the two sides and bottom- take the big side nuts off from the fork- adjust the screws I circled in yellow. Experimentation and patience required!Look, this bike cost $300 shipped. For that price, I had a reasonable expectation that the bike would not be perfect and would probably need some adjustments. If I wanted to buy the $2000 bike with $250 shipping charge, I would certainly have expected a higher level of quality. But for the cost I am very happy with my purchase.

I've had this bike for five weeks and use it 5-6 times weekly. I did a good deal of research on Sunny and other manufacturers of stationary bikes before purchasing this model. Amazon purchasers answered my questions and I found several indoor gym sites gave this bike excellent reviews. I did, however, purchase a Smart Guard five-year warranty, since the bike is made in China.It took about twenty-five minutes to assemble. Follow the minimal directions completely and don't cut corners. All tools come with the bike, which is nearly fully-assembled. All you have to do is add the pre-assembled seat base, the handlebars, pedals, cupholder, and the two base stands. Very easy. The bike is very well made and very well protected for shipping.The flywheel weighs nearly forty pounds, so, even a light resistance setting provides a good workout. The resistance adjustment knob allows for very fine tuning with only slight twists, allowing you to change settings easily and quickly while pedaling. You will get the best lower-body workout by riding hands free and sitting upright. The pedals have racing straps attached so your feet remain stable. You can easily stand up to ride, if you like.The bike is extremely quiet. You could use it in a room with a sleeping baby and not wake it. I'm glad I chose the belt-driven over the chain model. Reviewers agreed (here and elsewhere) that the belt-driven model is the better choice.The seat that comes with the bike is a racing seat. After two weeks, as I increased my riding time, it was too uncomfortable to use. I purchased the Bell Sports 7015679 Memory Foam Bike Seat from Amazon. Fits perfectly (you'll need to know how to change a bike seat, since it comes with no directions). The seat attachment base allows only minor forward-backward adjustment. I'm 5' 10" and have no problem reaching the handlebars; but I rarely use them. Again, you get the best workout by riding hands-free.Since this bike has no gears, you can't "coast," as on a real bike. Only a moron would attempt to dismount before coming to a complete stop. The bike is not a hazard or dangerous; it simply requires common sense (which seems to be in short supply these days) while using it.If you are not comfortable with Sunny's manufacturing quality, I would suggest getting a warranty. That way you won't have to deal Sunny at all. It does add to the cost of the purchase (~$80), but Sunny's bike is far less expensive than competitors. I probably would not purchase a warranty again, however. The bike far exceeded its presumed quality.I have been pleasantly surprised with the purchase and have found absolutely nothing cheap in its construction. Rock solid, quiet, well-manufactured. It's great to be able to exercise at home; this bike provides a great workout. I would recommend it to anyone.
