YOSUDA Under Desk Bike Pedal Exerciser - Magnetic Mini Exercise Bike for Arm/Leg Exercise, Desk Pedal Bike for Home/Office Workout

Very solid, quiet, fully functional as advertised, easy to assemble, heavy enough to not slide easily along the floor, light and compact enough to carry in one hand, made of good quality materials, and looks good. I am really feeling its benefits as I recover from knee surgery. My wife had asked for it for her general fitness and health, and I am happy I bought it for her because I now see we will both use it.

I bought this machine after seeing a few physical therapy YouTubers recommend this type of gentle, gliding motion for improving knee strength and cartilage. I've only had the machine for about a week, but I find it relaxing, definitely delivering a mild workout for an unfit senior, and something I can do when the weather is bad. I think it's the perfect prelude to venturing into a more strenuous fitness program.Incidentally, there are videos on YouTube that show ways to make the machine an interval training workout, as well as routines for working the upper body while pedaling. So it's not just "stationary bicycling".The machine is attractive, easy to assemble, with necessary tools included. It's a bit heavy, but that's necessary for stability. The motion is perfectly smooth, and produces only a faint whirring noise.The readout is quite handy. I prefer to track minutes, and the KMH monitor is most useful to show you when your effort is flagging and needs to be stepped back up. I am using it for my arms as well, as the smooth motion also seems to be giving my shoulders, elbows and wrists good exercise.I'm starting all the way at the bottom of the resistance setting. That's what my knees can handle.

Ordered this bike pedal exerciser with the idea of using it for pedaling and on the tabletop for arm movement. It is a solid little machine, has a nice handle for carrying, came with a harness of some type. After using this on linoleum and then on carpet, I realized that I would have to rig something up with the harness as it moves. I tried using it in my comfy chair while watching tv and it scooted enough that I had to move it back in place every 20 seconds or so. I attached the strap to the handle, I guess it's supposed to attach to an office type chair but I hold it like a harness as I can't wrap it around a large upholstered chair. If it weren't for the fact that an incumbent bicycle takes up so much room, I would have been better off with one of those. This can be a good option for under a desk or table, just be prepared to find a way to keep it from moving forward as you pedal. I would recomment this product as it is well made and very quiet but just know that even though it weighs 20 pounds, it does not stay in place.

I set this up a few days ago in anticipation of total knee replacement surgery which I had yesterday. I can’t say much about the internal resistance mechanism durability since I’m not supposed to use it until next week, but so far I’m very impressed. It felt smooth and comfortable in testing. The overall design is nice and includes a handle to move the device around easily. Not that I will be carrying it in the first few weeks after surgery.Set up was easy with clear directions. The mechanism is smooth and the resistance goes from nothing to harder than a floor device like this can really support unless you attach it to the floor with screws, and I can’t imagine home users are going to want to do that. In other words, at the highest settings, the whole device will skitter away from you even if placed on a non-slide mat and using the included bungee cords. By the way, the unit comes with a non-slide mat and the included bungee cords come complete with (lightly padded) handles for your hands plus clips to attach to the machine on the other side. You don’t need to buy these items separately.If you really want the high resistance settings, the mat probably works much better on a tile or wood floor. I have to set mine on a low nap rug, which may not be ideal. Likewise, using ropes instead of the bungee cords will prevent sliding altogether.However, that’s not really what a device like this is designed for. I will be using it for rehab, and for that it is perfect. If you’re having trouble deciding between a bicycle style device or an elliptical trainer style device, both the surgeon’s staff and my independent PT said the bicycle style device was the appropriate choice. Check with your PT, but I think this is the one you want.As a former bicycle shop owner, my only complaint is with the pedals. They are smooth but very stiff. Then again, you are wanting resistance from a device like this so it doesn’t matter. Plus, the stiff pedals mean you don’t have to master the skill of flipping the pedal up in order to use the foot strap. On balance, this is probably a good thing for most users. I just have my nose up in the air too much!Another minor niggle is that the instructions have you attaching the foot straps backwards from how they should be. You really want the adjustable side of the foot clip, the one with lots of adjustment, not the side with only two adjustment options, on the outside of the pedal. That will be the easiest place to grab the foot clip tabs and adjust the foot clip to your foot or shoe size. After attaching the foot clip, be sure that the fully adjustable side is parallel to the attachment clip on the pedal. It’s really easy to put them on the incorrect pedal. If the adjustment holes in the foot clips aren’t parallel with the attachment clip on the paddle, the plastic on the foot clip might wear prematurely and they will come off easily when using the machine. That’s probably the weakest point of the instructions, this was simply not made clear and the photographs showing how they attach our incorrect in my view.The only other thing to be careful about is to be sure that your foot is far enough forward in the pedal while using the machine. If you have average size feet, and you have the ball of your foot aligned with the pedal spindle, your heel will hang far enough back that you are likely to clip the rear support of the machine as you pedal. If you aren’t wearing shoes, this could be quite painful. Ask me how I know!The machine comes with a Bluetooth enabled monitor. It displays RPM, calories burned (probably not accurate), and other stats. There are suggest apps for both iPhone and Android phones. I had no trouble setting up my iPhone with the machine, but I haven’t really used the apps yet yet and I am not sure that I will do so for my intended use. But it’s there if you want it. I also discovered when downloading these items from the Apple App Store that there are many other similar apps that work with these kinds of exercise machines. Most, including the recommended apps, have in app purchases so you can have nicer stats or nicer scenery to pedal around. I would say choose whichever one you want as they are all likely to interface well with the machine.I will update this review if I find the machine has problems when I start to use it for rehab. However, I’m expecting this to be a stellar performer. I was offered a rental machine similar to this from the surgeon’s office, but I found that with my insurance, the price would be about the same if I just bought this one off Amazon. I’m expecting it will work just as well as what the surgeon would have gotten for me.
