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!

This bike has changed my life!! I was looking into getting a bike that I would have had to make payments on (name begins with a P) and asked for recommendations in my fitness group on social media and this bike was recommended over and over again. I have recommended it to several people, most of which ended up purchasing it, and they have ALL loved it!

Great bike

Easy to assemble, sturdy and stable, a bit hefty to move around but manageable, LCD is very useful/helpful, smooth transition between tensions, multiple adjustments makes for easy fitting and changing between riders. Would highly recommend to anyone looking for a model without build-in programming - think a nice spin bike from your gym. Nice job sunny! -Kurt
