I just purchased this bike a few weeks ago. Easy to assemble and great ride. I am not a super cyclist, so the bells and whistles were not needed for me. I highly recommend this bike for anyone who wants to get in a great ride a few times a week. I love doing SPRINT class on this. 5/5 in my book

Excellent Bike

I could not be happier with my Sunny Spin Bike!! I sold my first spin bike which had a 30lb flywheel and purchased this model. I am not missing my first bike at all. The 49lb flywheel and sturdy frame is excellent. For the price and the quality of this machine, you cannot go wrong.

I can't even begin to explain how greatful I am for this bike

I purchased the indoor cycling bike during the height of the pandemic. Was definitely going stir crazy and looking a way to use the peloton app without having access to my gym. The sunny website said they were experiencing delays in shipment because of the pandemic and I wouldn't receive the bike for ~4weeks. They were having a great sale, so I purchased it in the hopes of getting the bike in a month. Even the thought of getting it in that time frame lifted my spirits. I was SO shocked that I received a shipping confirmation THE VERY NEXT DAY. The bike got to my apartment 5 days later and was assembled (very easily) that same night. I've had the bike for 11 days now, and it has been used every day (some days twice) and it is my saving grace. My only wish is that it had a tablet holder, and I should have purchased the model higher to have gotten this. THANK YOU FOR SAVING ME FROM THE PANDEMIC

This item did not have some of the features I thought I was getting. Was told by your company could not return for a more expensive model even though it is still in the box without heavy financial penalties. This is extremely poor business practices and unethical. In a competitive world I will most certainly make sure you receive very critical publicity and discourage the public from buying your product starting today. I would have paid for a more expensive bike and made sure you got the publicity you would have earned as i have friends who were interested in purchasing a Sunny bike as well. You lose!!!

Sunny Health and Fitness
