Question: I have had this recumbent bike for four years and have had nothing but problems with the "feedback device" (dist, speed, etc). Replacement available?
Document: I've had my bike for a few years (got it back in May 2009) and for the most part it worked great. I've had the same problems others have had (the seat was always horrible and the tension doesn't really work), but by and large it fit the need I had for an easily moveable exercise bike with a small footprint.Last month, it broke. I disassembled it and found a busted belt.
I did notice most of the reviews were several months to a several years old so I thought maybe the product had been improved since the last reviews. I believe this to be the case. I have only had this bike for about a month and put 40 miles on it with no problems. The only negetive I can find so far is the thin padding and low quality of the cover material on the seat .
Yes, I loved this bike. You see, I live in a small house and I have to have my exercise bike right in the living room. (Explains why I haven't had anyone to dinner in over 2 years.) I bought the first bike in 2008 and when it gave out after less than a year I bought a second one, but I bought a 1 year replacement contract thinking that if it happened again I would get a free replacement.
I am really surprised with the ratings that others have given this bike. I would rate it a 0, if it was available. I had to return one because the belt inside got cracked/broken after 5 sessions and was emanating odorous (burnt rubber) fumes. Later, I called Amazon and got a replacement, the casing was broken on the replacement. The casing is pretty thin, so it was not surprising. Overall, what a shame, I dont know who does quality control on these bikes.
The display seems fairly accurate in terms of the monitoring speed, time, and distance (comparing to bikes at my old gym).I don't know why some people have problems with the seat moving around. I find it to be comfortable enough for someone my size (5'5", 125 lbs). I did some "tests" on the seat while biking one day in an attempt to figure out what other people were talking about.
I've had it a couple of years now and no longer use it because...Cons1. it's a pain in the you know what! This bike kills my back.2. It's not quite a 'real' recumbent. It's like half way between an upright and a recumbent....3. so the workout is like neither.4. I spent most my time trying to stay on and be comfortable in the bench seat.5.
This was just what I was looking for. I needed something to do besides workout DVDs on rainy/cold days when I don't want to jog. This bike takes up little space like an upright but has the comfort of a recumbent. It's nothing fancy but I didn't want anything fancy. I don't know that I could go more than 30 minutes on the seat. It's not bad, but it starts to be uncomfortable after awhile. It was easy to put together.
I was looking forward to receiving this folding recumbent bike. I had read many of the reviews that were available and most of the reviewers were very happy with the bike. Only a few out of over 100 reviewers received a defective bike. So I believed that it was not likely that I would receive a defective bike. I am in my mid 70's and have had back surgery so it took me a little longer to put the bike together.
I bought this recumbent exercise bike for osteoarthritis in my knee. Although setting up the bike took a little while, it was worth it. It's small footprint and folding feature makes it easy to use anywhere. The bike is very quiet while I'm riding it so that I can read or watch TV to help pass the time. The computer lets me know the speed, distance, time, and calories burned. It's good for home use and casual exercise.
This is our second Stamina Recumbent bike and we flat out wore the old bike out after 4 years. Its easy to use, comfortable, and best of all its portable so you can move it in front of the computer or tv if you want. And when you are done it stores in a small space. You cant slide it under the bed but it would fit in a closet.
