## Description

desertcart.com : Sunny Health & Fitness Smart Programmable Electro-Magnetic Recumbent Bike | Adjustable Resistance, Quick-Adjust Cushion Seat, Mesh-Backrest, Step-Thru Design, 300LB Capacity, SunnyFit App Connectivity : Sports & Outdoors

Review: FABULOUS! - After trying this model out at my physical therapist's office, I HAD to get one of my own! Honestly, I LOVE this bike! (I previously had a traditional, upright exercise bike that I rarely used because it was difficult to get on and off of it. Also, even though it had a "wider, more comfortable seat," it hurt my butt. Ugh!) So, THIS bike is not only easy to get in and out of (just step in and step out--no climbing), the seat is COMFORTABLE! It is like an ordinary lawn chair with a padded seat. JOY! As a result of the way more convenient and comfortable ride this bike offers, I look forward to exercising with it most days for 50-60+ minutes. Another really great thing about this bicycle is that you can still ride it when the power is out! The electronic programming will not work, of course, but the pedals and flywheel are operational. The programming is a bit complicated, but the bike comes with a concise instruction manual that helps. Once you get the basics down, it's easy. Assembly instructions are good, and all parts and necessary tools are included. Everything is wrapped separately and carefully to avoid any possible damage. The bike is quite heavy, so it really helps to have two people putting it together. After assembly is completed, the back of the bike can be easily lifted up by one person, using the built-in lift bar, and rolled into the desired room/position. There is a shallow shelf between the upper handlebars for a cell phone, tablet, or other skinny devise, and a water bottle holder on the main support tube. The seat distance is fully adjustable; I made marks for my husband and myself on the seat support slider with a Sharpie pen, so we can easily return the seat to the distance that fits us individually. Operation is silent. This recumbent exercise bike is one of the best investments we've ever made. Right now, the arthritis in my knees prevents me from walking or jogging for exercise, and this bike allows me to get the exercise I need and want without causing pain and further damage to my knees. (After surgery, I will surely continue using my bike.) HIGHLY RECOMMENDED!
Review: I love this bike--and AMAZING customer service! - As someone who's had four or five different kinds of recumbent exercise bikes over the years, this Sunny is my favorite. The drive mechanism is super smooth and silent, and I love the soft seat and the mesh-backing. The latter is a revelation for people like me who push themselves hard and sweat a LOT while riding. The controls are straightforward and not too fancy, which is what I wanted. At this price point, there's not a single other bike out there as good as the Sunny. My favorite thing about the bike, though, is Sunny's customer service. I felt compelled to write this review because I saw a few one-star reviews that commented on the company's poor or non-existent customer service one you've bought the bike. That's completely false. I did have a problem with the bike's belt about ten months in, after the warranty ended. At that point, a long, detailed, and daily conversation began between me and Steven, Sunny's main tech-support person, on how to get my bike back to perfect working order. Seriously, at least 50 emails went back and forth between us, and Steven was so knowledgeable and prompt and respectful. He has to take in customer questions in the order he receives them, but I never waited more than 24 hours. Even with the bike out of warranty, Steven and Sunny helped me with parts and tools and so much advice. At this point, I have a perfectly new bike and Sunny covered costs they had no obligation to given that the warranty had ended. I just hope they pay Steven what he's worth, because he proved to be saint in how hard he worked to help me out. Seriously, I felt like the guy cared about me as a person, which was really refreshing. So yes, a five-star bike with ten-star customer service. I've never been treated so well by a company of any kind before. And that is absolutely 100% the truth. (And nope, I don't work for Sunny and they didn't pay me to write this--they didn't even suggest I write a review.)

## Questions & Answers

**Q: How do you order the flywheel belt?**
A: Love the bike but getting replacement parts is a  hard thing to accomplish.  Every time I called Sunny it took 4 -6 weeks to get parts.

**Q: I am short - 5'3". Is this bike ok for me?**
A: I am 5’1” and I can slide the seat forward enough. The only problem I have with the bike is that you can’t recline the seat so you’re sitting straight up. This is a problem for someone with back issues like me.

**Q: Does it come intacked or is assembly required? How much does it weigh? Are there wheels for easy moving?**
A: Arrived in one carton and requires assembly. I had one problem where the holes for two bolts didn't align. Was an easy fix to drill holes to align. Weighs about 130 lbs in the carton, I moved it by dragging and wasn't to bad. The unit does have wheel on the front and a handle on the back for relative easy moving after assembly. May not have all the bells and whistles, but very stable, well made comfortable and quite.

**Q: Where do you get parts for the bycycle?**
A: If you are in need of replacement parts, please feel free to reach out to us at support@sunnyhealthfitness.com.

### ⭐⭐⭐⭐⭐ Great Recumbent Bike!
*by M***N on March 25, 2024*

I purchased this bike to augment the exercise bike I was using at physical therapy. It has only been 2 weeks, but I am really enjoying it. It came well packaged, and everything was included (including the tools needed for assembly). My son put this together for me and it took him about 2 hours. It wasn't very difficult. However, a couple of the bolts would not line up correctly and it took some maneuvering to get them to work without damaging them (or the bike) in any way. Everything else went together quite easily. The bike is a joy to ride. You have to either program a level yourself or use one of the preset programs in order to take advantage of the levels of resistance. Understanding the programming took me a little bit of time, but I managed to get it down. I think that the instructions could be a clearer on how to set the levels of resistance - it took a little trial-and-error to find out how it was done. The bike is very sturdy and solid. The seat is comfortable, easy to adjust, and locks in tight. Although, if you have more than one person using it, you might want to use a sharpie to mark the bar under the seat so that you know where to put it for each person. Pedaling is smooth and the bike is stable as I ride. I love the "shelf" where I can put my tablet and watch virtual bike rides as I work out. As I said, it's only been 2 weeks, but I am very pleased with the bike and would definitely recommend it. I will know more after a few months of riding as to how everything holds up. I hope that it lasts for years, but time will tell.
