Incredible Value

I wrote a review on this bike, but it seems like it didn’t post. This bike is incredible. Sturdy, easy to assemble, super quiet and rides like a dream. I have wanted a spin bike for at least 6 months, but have been using a trainer. The problem was I was burning up tires and need constant tune ups. I finally decided on this one and WOW! This thing is built like a Sherman Tank and is better than the bikes at the gym. I didn’t want to spend $2000 on one of “those” bikes and I’m glad I didn’t. This one will no doubt last for years and is equal in quality. If you’re looking for exceptional quality at a lower price don’t hesitate. I’ve been riding indoor and outdoor bikes for a long time and this one is exceptional. I am one happy customer!

Solid bike! Way better than expected.

Ordered bike and even with the COVID-19 delays, it got here fast (less than 10 days). I normally ride a high end spin bike at my gym and I was amazed how this bike rode. Much more solid (I am 6'2 and 260). It does not wobble and the resistance is great. No odd catches when turning the dial. Very happy. I got the Peloton app and added a phone holder to the top so I can do spin classes at home. Also added clip pedals so I can wear my bike shoes. WAY cheaper than a Peloton bike. Super solid and a great ride. Would highly recommend.

I have never taken a spin class but was always interested in taking a class. After 2 of my neighbors bought a Sunny bike (one is a spin instructor) and had rave reviews, I decided to purchase one. I have used it at least 3 times a week since I received it. I love this bike. It’s quiet, the ride is smooth and very easy to set up.

Extremely happy with purchase

Love that it's fully adjustable which makes changing settings easy between my wife and I. This bike is definitely heavy duty and performs smoothly yet quietly. We're really happy with our purchase and have recommended this bike to others.

Wish I had purchased this indoor cycle years ago; excellent indoor bike. The heavy-duty flywheel and belt drive offer a very smooth and quiet ride. Highly recommend!

Asuna 5100

Sunny asked me to substitute Asuna for the bike I originally ordered. I couldnt be happier. I am 72 years old and 278 pounds. I just finished a twenty minute workout. I love the fact that I can ride 20..30..45 ,minutes whenever I want. Easy to setup and rides really smooth. Glad I went with the belt drive and magnetic resistance. Sunny you made me a fine product. Namaste;
