Hopefully it will get better with time
I bought this bike hoping it will help me as I am recovering from a total knee replacement. I can use the bikes at the physical therapy center very well and have no problem doing the assigned program and time. Unfortunately, that brand of bike is over $7,000 and way over my budget.I am 5ft.6in. tall and due to previous back injuries, it was recommended I get a recumbent bike. I tried going to local sporting goods stores to check recumbent exercise bikes out, but only one store had any in the store. I even called bike shops in my area but recumbent exercise bikes are not carried in any of them. I had to rely upon reviews.On this bike there is no way to raise and lower the seat height except to slide the seat forward or back on the slide mechanism. First time on the bike, I could reach the pedals, but to do so and not hyperextend my legs, I had to slide the seat closer to the pedals. That forced the bend in my knee to be greater than I could bend it yet. I am hoping it will get better with time. My range of motion in my surgical knee is currently 100-104 degrees on my own. With my physical therapist pushing on the knee, it is 115 degrees. After discussing it with my physical therapist, I added cushions to the seat and if I go very slowly on the bike, I “CAN” make a full rotation, but to do so, I am currently swaying side to side on the cushion to get the bend in the knee to make a full rotation of the pedal and not torque the knee doing so. I hope is as my range of motion increases, I will not need as many cushions and won’t have to sway side to side.
Thank you for your feedback
