Non-Slip Handlebars

Help prevent calluses with the improved Sunny Health handlebars. Advanced ergonomic designed handlebars deliver a comfortable ride and allows for multiple hand positions. Padded and slip free to provide extra safety and ease. 



Bikes with magnetic resistance never come in contact with the flywheel, resulting in a silent, stable and virtually low maintenance experience. The closer the magnet the greater the resistance will be.



The heavier the flywheel, the smoother the ride! Creating more momentum for longer periods of time keeps your workout going the distance. Sunny Health and Fitness' 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!


Emergency Stop Brake

The cycle bike trainer resistance system gives you the experience of a realistic, real-road feeling while the built in push down emergency brake will bring the bike to an immediate stop.



The comfortable seat can be easily adjusted for height and proximity to handlebars. Easily adjust back and forth and/or up / down) for convenience and stability so your workout can remain comfortable when riding for long periods of time. Adjustable seating allows for multiple people in your household to use the equipment comfortably and efficiently. Having the correct seating adjustment is important to assure you won’t fall while giving it your all.



Proper foot placement is essential to any biking workout! Ensure your feet are securely in the right place with Sunny Health and Fitness's added foot cage feature. Avoid foot slippage at increased levels of speed and intensity!



Making the transformation of your home into your own personal fitness studio is effortless with these convenient transport wheels. Simply tilt and roll out for use or away for storage, no need for heavy lifting or muscle strain. The wheels at the front of the unit allow the user to move their equipment around with ease, from room to room, or store it away out of sight.

Good small bike

Helpful for exercising while stuck in an apartment during Covid restrictions. I’m 4’11” and this bike works for me.

Great indoor cycling bike with magnetic resistance

I am loving my bike. It rides very smoothly and does not take up too much space. I am so glad I purchased it and have already recommended it to a friend!

Expected better quality

The bike was straightforward to assemble. We did notice that part of the back stand was unfortunately dented due to packaging. We were able to fix it as well as we could vs having to shipt it back. Bike is quiet and feels sturdy. We have been using it daily. Today we noticed all this black looking dust near the flywheel. Not sure what this is from.

Sunny Health and Fitness

Excellent Purchase!!

I’m a runner who has fallen in love with the peloton digital app, but without the budget to buy a treadmill. With the coronavirus stay at home happening I decided to grab a bike and give it a whirl. I AM OBSESSED. This bike is great. I’m all in. Do not hesitate. Buy it. Spin for you!
