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' 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.

Bottle holder keeps your favorite beverage at arm's length! No need to stop to sip.

Love it!

I bought this as part of my DIY Peloton and have zero complaints about the performance of this bike. It feels rock solid, which makes me feel like this was a great choice. I'm new to indoor spinning so I don't have experience with other bikes. And for reference, am 5'6" 145lb. Shipping was great and it was relatively easy to put together. The hardest part was getting this thing out of the box!

Quality, durable, practically maintenance free

I decided to purchase this bike after an exhaustive searching and researching spin bikes. After a hiatus from fitness, I remember very well what a quality bike should look like. The 1805 met every checkbox I had and the price was great. It's sturdy, has all the functionality I wanted, and combined with an HR monitor, cadence monitor, and Peloton App I can get an exceptional cardio workout right from my own home! Another bike I considered where the L1 Spinner. I wanted durable, low maintenance, and a no-frills experience. Something reminiscent of the various gym spin bikes of the past. This bike has met and exceeded all my expectations. A great investment in myself and with COVID, turned me onto a home gym option which I never had considered in the past.

Great Bike!

I was missing the spin classes at the gym due to COVID. After doing a lot of research my husband and I decided on this bike because of the reviews and the cost. I LOVE this bike! It is better than the ones at the gym! It is super sturdy and smooth as silk. We did replace the pedals so I could use my spin shoes. We ordered through Amazon and it came 4 days BEFORE the expected delivery date. I got the Peloton app and stream the classes through my TV. I could not be happier with this bike. I normally don’t write reviews but the reviews that I read helped me to make my decision. I hope this review helps others to get this bike!

Very pleased with our new bike, no complaints!

We have been beyond pleased with our new bike. Assembly took an hour or so and was a snap with two people. Have used it for a few months with no mechanical problems or mystery squeaks or noises. Bough the Garmin cadence tracker and use the Wahoo app to keep track. Enjoy using the Sunny Health videos on YouTube, just wish they added more new ones. Using our bike has become a daily habit and we made the right choice with this bike!

Best Home Gym Investment

My gym closed due to Covid-19 so I had to find a way to get my cardio workout. After researching online and looking at different price points I decided on the SF-B1805 and purchased it on Amazon. Took 2 months but totally worth it. The bike took about 30 mins to assemble. It is very solid and can handle all the spin class routines without any problems. Having a water bottle holder and device holder was important to me. I bought a Wahoo Cadence sensor from a local bike shop to maximize my workouts and track my progress. My very own bike to spin when I want and how I want.

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!!
