This unit is on the heavier side, but that’s a good thing. it feels solid and has beefy internal components that should last a long time. Before this, I tried two other brands/models. One had such weak tension it felt like I was just moving my legs through air—completely useless. The other had more tension, but when I checked inside, I realized it was just a spring with cloth pressed against the flywheel. Honestly, that looked like a fire hazard if I used it long enough! definitely not something I felt safe with. That’s why I went with this Sunny Health model with magnetic tension. The resistance feels smooth, reliable, and safe. Maybe it could use a little more tension, but honestly, if it had much more I’d probably just end up kicking it away while pedaling. Overall, it’s exactly what I was looking for and definitely worth buying.

LOVE this thing. Better than I was expecting, in that it's nearly silent. It's not suitable for major workouts but awesome to get bursts of movement through your day -- gets the heartrate up for we relatively sedentary people. It removes all the barriers of making it to the gym when you're tired. Y'know how we're suppose to take a walk after each meal? This checks that exercise box well enough. Easy to put together. I just wish the packaging was cardboard instead of toxic foam (gross).

Installation was quite easy and I was using this in less than 15 minutes. The unit preforms great, feels well built, and gives me a good workout, and stores easily (as long as you have an area for it to slide under). The stability is questionable as this house mainly has carpeted flooring, and my chair is a computer chair.. so sliding is a problem. Using it when sitting down on my bed keeps me from sliding.. but the unit itself has slid out from under my feet (nomatter how I position myself). I wonder if there’s a rug I can get for carpets, that prevents itself and what you put on it from not sliding out from under your feet. Other than that, fantastic product, highly recommended. 👍

I went from floor nursing, walking miles a day, to a telephonic phone nursing position where I’m sitting in a chair for essentially 8 hours a day. My legs would hurt from dangling all day in the chair. I needed something to help keep me moving, since I’m so used to waking. This was definitely my answer! I was a little hesitant at first based on the reviews about the pedals stripping and essentially becoming useless after a couple months of use. And I’ve only had this for 5 days so far. So I’m hopeful that the pedals hold up. If not, I’ll change my review. The display starts up when you start pedaling and shuts off after 4-5 minutes of no activity. No need to take the battery out. The pics above show what I did on my first day using it sporadically over 8 hours. It has a distance counter which is nice. The calorie counter seems to count a little less than my Apple Watch, but it is still a great counter for those that don’t have a smart watch. It said I burned 688 calories, while my watch said 753. The counter seems to be based on average, while my watch uses my heart rate. Yesterday I did 32 miles and burned over 800 cals. I do wish that this had a higher tension setting. I would say I’m in good shape, and I’m on the highest tension of 8. But I also know that this isn’t meant to replace a strenuous cardio workout. My heart rate ranges from 100-110’s but if I’m consistently pedaling for 30 mins or more, it will get up to 130’s and you can feel the sweat. Also, I can definitely feel the inner thigh burn. Setup was fairly easy. 10-15 mins max. You really only have to assemble the end plate, front stabilizer, and pedals. I do think the pedals were the hardest part. You screw them in, which was easy enough. But putting the bolts on the back was challenging. Sounds easy until you go to do it. They give you very detailed instructions and even warn that if you don’t put the pedals on correctly, it can harm the product. It seems I put them on right, so I hope it holds up with how much I use it. It does have a carrying handle and would be easy to move around the house. If you are thinking about lugging this back and forth to work, I would probably just get one for each location. It does create a little bit of sound, but mostly a hum. I use mine in between patient calls so I can’t tell you for sure if this hum would be audible on a phone call. I work from home, but I do think it’s quiet enough to not disrupt your office mates. I heard a click today and was worried it was the product but nope! It was my knee. So I’m taking a break. It is addicting and I can see how easy it would be to overwork yourself on this. You can apparently use for your arms, but I haven’t done that just yet. I was considering the deskcycle, but wasn’t sure how committed I would be to using a pedaler so I went with this option since it’s cheaper at $120 vs $190. So far I’m very happy with this option. As I said, I’ve only had 5 days so I will update if it starts making noise, pedals start stripping, or what have you. This product seems to be used a lot by the elderly or people who have had joint replacements and I can see it being great for that use as well. Very multifunctional for people of all different activity levels.
