44 LB Flywheel

The heavier the flywheel, the smoother the ride! Engineered for speed and stability this flywheel will create more momentum for longer periods of time keeping your workout going the distance. Sunny Health and Fitness's Flywheel is second to none when it comes to feeling like you are really riding outdoors! No more jerky, out of control movements, regardless of speed or resistance level.


4-Way Adjustable Handlebars with Device Holder

Improve your fitness experience by securely placing your phone or tablet in the tablet holder. Utilize this added accessory by keeping track of your fitness progress on the Sunny Health and Fitness app, follow along to fitness videos, or listen to your workout playlist. Whatever the use, you won’t be disappointed.



The main function of the magnetic resistance is to provide quick, easy and reliable changes to the resistance level. Magnetic resistance is generated by single or multiple metal disks through a magnetic field providing infinite levels of resistance. The closer the magnet is to the flywheel, the greater the pedal resistance will be. Unlike bikes with traditional tension systems, bikes with magnetic resistance never come in contact with the flywheel, resulting in a nearly silent, stable and virtually low maintenance experience.


Micro-Adjustable Resistance

With a simple twist, you can increase or decrease resistance, so your cardio workout can remain challenging and effective throughout your fitness journey.

High quality bike ride!

The assembly was relatively easy, although the bike frame itself is a bit heavy, but two people can definitely do the job. I use my bike daily along with the peloton app! I kept going back and forth concerning whether to buy the Peloton bike but I couldn’t bring myself to spend that money plus the extra monthly membership even after you pay off the bike. I did my research and this bike was continuously in the top five for indoor cycling bikes and I have no regrets! It’s quiet, smooth and can handle various positions and speeds.

Nice smooth ride but frame quality control fell a little short

Very smooth resistance, sturdy bike. The frame is not perfectly square to the floor (leans to the right), the seat if full extended leans to the right, and the handle bars do not sit perfectly square on the frame. But I probably notice all this because I am an Engineer. Typical Chinese quality control, but for the price I'll get over it. Super smooth resistance and a sturdy bike. I just need to look forward while riding and not down at the flaws in the frame.

Excellent Bike for the Price

So thrilled with my purchase. I did a full week of research before settling on this bike. It's incredible quality for a fraction of the cost of a Peloton or NordicTrack. Although I sometimes wish it had a monitor, I purchased a Wahoo Cadence Monitor off of Amazon and it has made a world of difference.

High quality bike!

Exceptional customer service. The shipping was quick, the bike was super easy to put together (my sister helped me) and I LOVE IT. I use it for my Peloton work outs; didn’t have to pay the price of a Peloton and I didn’t have to sacrifice on quality.

I’m sooo glad I purchased this right when quarantine began. I went back & forth on several options and am crazy happy with my choice. It’s beautiful and ridiculously quiet! Everything about it is very comfortable. I put it together myself in about an hour. Best purchase!!
