A great ride that's super sturdy!

So far, we love our Sunny bike. My boyfriend and I use it about every other day right now, and it is a really smooth ride that feels just like being in the spin studios I used to go to. I like the simplicity of the time/distance/calorie tracker, too. My biggest concern was how sturdy the bike would be and if we'd need to be tinkering with it constantly to keep it tight - but the seat, handlebars, etc. stay tightly in place. As a bonus - assembly couldn't have been easier and took about 20 minutes.

Very happy

I am very happy with this product. As a college athlete I enjoyed biking as an easy cardio option, but have now been out of working out for a few years. I have used this bike every day for 12 days in a row, plus my wife has used 5-6 times as well. It is working great. It is sturdy, quiet, and smooth. The seat is wider than I thought it would be, but is what you would expect out of a cycling seat. It is comfortable for the first 30 min. or so, then it can become a little less comfortable. Again it is what should be expected. I have never been on a bike that I would say has a more comfortable seat. Set up was relatively easy, again what would be expected from this type of product. All equipment needed to assemble is provided, which is great. I was very impressed with customer service at Sunny. The box was damaged slightly during transport, scuffing up the wheel. The bike still works great, but it didn't appear to be in new condition. The company was great and did what I expected to resolve the situation very quickly. I will definitely look to Sunny again in the future when looking to purchase exercise equipment.

Great bike for the price!

I received this bike last week (shipped very quickly), and so far, I'm extremely happy with it! Super easy to assemble (all that's required is the placement of the seat/handlebars/pedals), and the wheels on the base make it easy to move if needed (though if you're a small person like me, it is still pretty heavy and cumbersome). The bike rides very smoothly and is oh-so-quiet, and is easy to stabilize no matter the floor surface. The digital monitor isn't of much use to me, but that's such a minor thing given how much I like everything else about the bike! It is also nice to use the bike classes on Sunny's Youtube channel. A solid substitute for not being able to go to regular spin classes!

Top of the line

Unpacking: took a bit of time as this was packed to guarantee no damage during shipping. Was able to do by myself but an extra pair of hands would have been helpful. Directions and assembly: Best written directions i think i've ever had. Easier then I expected to assemble. Took 1:20 min. but can easily be done faster. Performance: Quiet,smooth and comfortable. At one point I applied a little lubricant (WD40) to the brake pad. Took a few tries to adjust the seat for comfortable ride. I chose this model because of the measurements,seat to pedal etc: This being my first experience on a spin bike the seat took a little time to get used to ,but after about a month of riding 40 min. most days its getting easier. The episode length of the series im watching. .. The bike is easy to move and does not take much room on the floor. I've had gym memberships for 60+ years and can say that this Sunny Bike is a well made and thought out piece of equipment. The resistance changes with a touch ,mounting and dismount is easy ,the water bottle holder is placed perfectly. The exercise computer gives just enough info for me. While it is easy to read in daylight i do wish it had a light as im in a corner of the room with less light available. You can have a casual ride or a strenuous workout on this great piece of equipment. And I should mention that the price is fair for this quality. tom

Great product & fantastic customer service to boot!

I purchased this bike (SF-B1423) after Google-ing "best exercise bike" & stumbling across Sunny's products in the midst of that search. So far I am very pleased with this has a very solid & smooth feel to it. In addition to being extremely pleased with the product, I also have to express my appreciation of a fantastic customer support staff. I experienced a delivery issue & had to contact Sunny's support staff regarding the issue. Having my typical pessimistic attitude, I assumed "Well here goes...I'm out the bike & the money". That attitude was completely blown away however after Mihaela assisted me in regards to rectifying the delivery issue. Sunny went above & beyond...I would definitely recommend them to anyone!
