I was not sure about the performance or quality, but this machine is very good. It is what I needed to begin my physical therapy. It is very quiet and not overly large for a bedroom. So far I am very pleased with the recumbent bike.The best large product that I have received where everything was spelled out. Easy to assemble, sturdy product, packed really well, and easy to work out on. I love it!RECUMBENT BIKE WAS VERY EASY TO ASSEMBLE! WORKS GREAT! AS NICE AS ANY EQUIPMENT AT MY PHYSICAL REHAB. STURDY AND SMOOTH TO OPERATE. WITH MEDICARE LIMITING HOW MUCH PHYSICALREHAB ONE CAN GET IN A YEAR, THIS WILL LET MY WIFE AND I CONTINUE AT HOME. GREAT ADDITION TO MY HOME GYM. RECOMMEND IT TO ALL BUT ESPECIALLY TO SENIORS WITH SHOULDER/ARM ISSUES.Why did we buy this Sunny Health & Fitness bike? Because they offer live, phone, customer service. We had purchased a bike from an Amazon major competitor but it was a very poor product. I do want to say, the competitor's online buying service, delivery and return service was excellent. No issues with that part. The bike was broken (A disk chain guard) and I tried 3 different days with about 12 calls to different departments at Cap Barbell in Houston, TX, to reach customer service for a resolution and they never picked up. Not once. A few times I had the opportunity to leave my name and number but it wasn't at the right department and they never called back anyway. Every time I contacted the right department the automation said the mailbox was full! After the third day we decided to return it. If their office was closed due to Covid, because Houston has had a bad outbreak, they should have updated their answering service to indicate that. But what about remote service? Anyway, stay away from that company as there is no phone support. We decided to try Sunny Health & Fitness through Amazon because their product had the features my wife was looking for. But I had to test their phone support first and Giovanni confirmed that they back their products with live, rapid service. I was satisfied and made the purchase of their product. Amazon stocked it and delivery was free so 3 days later two polite Amazon drivers delivered our new bike exactly where we wanted it. The following day I put it together and it was an easy job of it. The instruction booklet was clear and concise. This product is well manufactured and a top quality piece of exercise equipment. I didn't even see a scratch on it. Everything went together well and in place. Just be sure you are careful attaching the pedals correctly. It would be easy to mess up the threads if you tried to put them on the wrong side. They are a fine thread. But Sunny makes it very clear where each one fits. Labeled well! Once everything was tightened step by step and the cables snapped together for the display to work (even the batteries were in place, nice one Sunny) I gave it a try. The seat is very easy to adjust and has plenty of range for long legged or short legged individuals. Our model has the hand cranks and they are easy to adjust too. The tension can be adjusted for either the hand cranks or the pedals and it is more than adequate for us. We are Seniors and my wife recently had a full knee replacement so it is exactly what she needs. We are very happy with this bike purchase. It cost about $50 more than the other one we bought but the quality and service are far superior to the other one that we returned. Everything about this Amazon purchase and the bike has been an excellent experience so far. This is one solid piece of equipment. Well built (and I don't mean by me either). Stable as a rock! We bought the right product and the price and service was great. And so far, I haven't needed to call Giovanni back! Thanks Sunny and Amazon!I have Parkinson’s disease so balance and muscle aches and stiffness are a daily issue. I try to stay active but when I can’t I ride my bike. This is perfect for my needs.As other review mentioned, there is issue with the foot pedal installation. Beside that, works fine.I am really pleased with this product! It is extremely well made and sturdy. I am a big girl and I was worried it would be uncomfortable in the seat area, but it is actually very comfortable. My only concern is the arm exerciser sometimes causes my arms to hit my knees when I use both at the same time. I am 5'11" tall. If I slide the seat as far back as possible it helps, but it does still happen occasionally. It is not a deal breaker for me as it is still a great deal in my eyes, but worth noting. If you are taller it might be a problem.Having been out of shape for a long time, I needed a bike that was comfortable, strong enough to safely hold my weight, and would have enough resistance to give me a workout. So far this bike seems to check off all three of those requirements for me.The bike was easy to assemble. Instructions recommended you have two people do the setup, but it was easy enough to do myself and only took 30 minutes. Probably could have set it up a bit faster but I wasn’t rushing.The bike definitely feels sturdy and well made. I was concerned about my weight being too much for the bike, even with the 350lb weight limit. But this bike seems super sturdy and it doesn’t seem to be a problem. The bike is also pretty comfortable. My only complaint about comfort is the seat back feels a little short. It would have been nice to be able to raise or lower the seat back slightly.Finally, the only other reason this bike get a 4/5 is the computer with the stats. I cannot get the time and distance to reset. This is a bit annoying because if I want to keep track of my time and distance with each workout I have to do a little mental math and add it to the current reading.Overall this seems like a great value for the price. It doesn’t have a lot of the bells and whistles like equipment in actual gyms and workout clubs, but I knew that when I made the decision to purchase. It’s still sturdy, comfortable, and makes for a good quick workout at home when it’s too cold to be or want to leave for the gym.Es una elíptica muy buena al ejercitar piernas y brazos. Para una persona que inicia a hacer ejercicio o es sedentaria le va a ayudar mucho. Lamentablemente los niveles de resistencia para hacer más esfuerzo son muy bajos. Esta maquina puede ayudar mucho a personas de la tercera edad a mantener su salud. Esta muy bien diseñada, es muy bonita, es estable y no ocupa mucho espacio comparado con una caminadora. Se limpia fácilmente. En el armado no tuve ningún problema solo hay que leer bien el instructivo. Le pongo 4 de 5 estrellas ya que yo hago ejercicio y si, en cuestión de niveles de resistencia, esta para un usuario que comienza o tiene no mucha practica.Muy recomendable para personas adultas la compre para mis padres de más de 70 años les ha servido mucho para ejercitar sus músculos. el maneral para los brazos como la bicicleta suficientes para darles acondicionamiento físico de acuerdo a su edad.Me encantó! Buena relación calidad precio, no fue difícil de armar, todo llegó bien y puedo rehabilitarme en la comodidad de mi casa a mi pasitoTime to get some exercise and I hate walking in the heat and humidity! Easy to put together and surprised how quiet it is , didn’t even have to put up the volume of the TV.Absolutely fantastic for someone who has had spinal cord injury and needs to exercise arms and legs it is perfect for them noise level is hardly not at all
