Portable Desk Cycle Pedal Exerciser - Adjustable Hand, Arm & Leg Fitness Machine for Seniors - Low Impact Rehab Equipment & Folding Mini Stationary Bike - Perfect for Home Office, Physical Therapy & Elderly Exercise

This works well. My main issue is that it is really light weight. If you use it under a desk that isn’t right against a wall (like mine), it will slide while you use it. I found putting a box behind it stops this.It obviously isn’t meant to replace work outs or anything. But I have a job that involves a lot of sitting. This helps me stretch my legs/ circulate the blood while I’m reading reports.I can sit in my chair and peddle to my hearts content It is light weight but sturdy. Love it!!❤️Unlike most reviewers, I bought this to use primarily as an arm bike. I wanted an inexpensive form of cardio that didn't involve my legs, since pretty much all other cardio is leg based or dependent. That being said, I tried it out as both an arm bike and a leg pedaler. Used as an arm bike, it's definitely a workout for the shoulders. I think I probably need to work on building some endurance for my shoulder muscles before I can use it effectively for cardio. While tightening the tensioner seemed to make a difference when using as an arm bike, I definitely didn't feel it as much while pedaling with my feet. I'm assuming that's because my legs are stronger than my arms but the angle of the limbs could have something to do with it too.Some minor complaints: It does have a horrible smell straight out of the box. I am going to try wiping it down to see if that makes it go away faster. Also, the hole for the tensioner is offset a little bit. It seems like screwing the knob in bites the side a tiny bit. And the pedals are somewhat uncomfortable to use with bare hands/feet.Slightly larger complaints: The feet aren't as grippy as I'd like. And they can rotate during use so that the machine becomes unstable. Also, it's not really ideal to pedal backwards. Doing so feels unstable and results in rocking the machine. And for me personally, I do wish the pedals were a little further apart. I think their distance is more suited to foot pedaling than to arm pedaling.All of that being said, I do think it was more or less what I expected to receive and entirely reasonable for the price paid.This portable pedal exerciser is exactly what I wanted. It's all set up when you take it out of the box, you just have to add the tension knob. My only complaint is that it smells awful. When I took it out of the box it smelled like I was at the mechanic. I can't figure out why it would smell like that, and the smell will not go away.Great for those home bound who need some exerciseRehab for knee replacementTwo of the feet were cemented in the wrong position. Not changeable without compromising unit.Works well, super easy and quick to put together. I highly recommend:
