I have 2 of these bikes in my home, and my daughter also purchased the same bike the day before I purchased this one. Of the 2 PLENY bikes I personally bought, the first one the belt broke within a few months and PLENY did replace the bike for free for me. That is the bike I am still using today. It's been working for almost 2 years, I think and doing well. Though I ride it often, I am not using it at a high resistance usually. I'm usually between Resistance Levels 3-9. The max is Level 14.When my husband used it for a couple weeks, he used it at high Resistance Levels and it started to make some funny sounds, but since then, he hasn't used it and it doesn't make funny sounds.My daughter purchased this same bike back in June on Amazon Prime Day and hers immediately began making noises maybe less than 10 minutes into riding it. I took out part of the cover and it seems the flywheel is crooked. Since it was still within the return period, we returned it for a replacement, which my daughter just got yesterday. She has yet to assemble it.After having my 2nd new bike that I also bought on Amazon Prime Day, which will be used as a backup, I did just assemble it a few days ago and it seems to be riding smoothly, but I did not ride it very long.My suggestion is if you have to return the bike within the period (usually 30 days, but somehow we got 3 months by purchasing on Amazon Prime Day), make sure you save the box, take pictures of how everything is laid in the box BEFORE you take things out. In fact, it's best to label the bigger Styrofoam pieces with the part that goes in it, because Amazon will not pick it up assembled. You must have the bike disassembled and placed in a box.Save your original box because if you don't, you'll have to find a box big enough to hold the bike, or 2 boxes and then call Amazon to get an extra shipping label to ship both boxes. Thankfully, we had my new bike to use as a guide to return my daughter's first bike back to Amazon. We got everything to fit perfectly. Praise God! Taped everything back and I had my son help me carry the box to the UPS store - it is a bit heavy and very bulky.So the reality is out of 3 original PLENY bikes we got, 2 had to be returned because they were defective. But, if you get a good bike, and you're not using it regularly at high resistance levels and cycling for a long time, it should last you quite awhile. My husband tends to tax the indoor cycles and we've gone through MANY cycles. We probably should purchase one that is over $1K because he's a total beast when riding the cycles.I cycle more for leisure and movement, to keep my blood sugars low.I do love that it doesn't take up much floor space as it does fold up. You have 2 different seat positions. The main thing I don't like is the Reset button. I wish it were recessed because anything you place on top, like an iPad, it will Reset it. It's really a lame design. However, I found a way around this. I use a bathtub caddy over the console. It allows me to hold my iPad, and the caddy fits over it without touching the Reset button. It looks strange, but it works.Before I begin my review there are a few of things you need to know about me. 1. Before I buy anything, I do a ton of research. Drives my wife crazy sometimes, but I want to make sure to avoid situations like this. 2. I do not like conflict or giving negative feedback. 3. I try not to allow my emotions to take over. 4. I always start problem solving by looking at my role in the problem. Okay, that said on to my review of the Pleny 3 in 1 folding exercise bike.First, I will give the positives. It is easy to put together. Pleny provides a link to a video about the assembly of the product. Even though the product in the video is not the same, there is enough similarity that anyone with decent ability to follow directions and extrapolate, will find putting it together pretty easy. The tools they provide are the standard, dinky tools. My 12 year old son and I made it a father/son bonding experience. The product is light weight and easy to move regardless of whether it is folded up or not. It also feels sturdy and not likely to tip over. The pedals are solid and the flywheel is very smooth and quiet.The minor negatives are as follows: The screen is not adjustable, so you cannot see the readout while you are in recumbent mode. Not a huge deal as you might be watching television or listening to music as you work out. More like a nuisance issue. Adjusting the bike can be tricky. You have to unscrew the locking pin far enough to be able to disengage the locking pin, then you have to make sure it doesn't splay out flat, which is its natural tendency based on the center of mass. You have to keep the locking in pulled out so as to not engage each and ever level causing a repeat of the problem above. An Adult can manage it, but if you have younger adolescents who want to do it, it might be frustrating.So, here are the things that contributed to the one star review. I am a big guy, I will not lie. I am currently between 270 and 280 pounds (the reason for wanting a recumbent bike to ease tension on the knee and ankle joints) I have been walking on my treadmill and in the community but my foot started to hurt (probably a combination of old sports injuries, my weight, and repetitive stress, even from just walking). The doctor said to try to do something less weight bearing for a bit so my foot can heal. Reading the reviews and noting the 300lb weight limit, I thought that the Pleny would be okay. I was wrong in this case. Perhaps I just got a defective product (as can happen) but the design has a significant drawback. The seat assembly is adjustable, which is an awesome idea. It means that when you convert from upright cycling to recumbent and vice versa, you can adjust the seat to make sure it is level and you aren't tilted forward on the recumbent or backward on the upright. There is a locking pin on the rear of the seat assembly that engages in two holes in the assembly which controls the tilt. The problem is, that when you are in recumbent mode your full weight is on that one pin, which is about a quarter to half inch in diameter and partially hollowed out for the locking pin to engage on a spring action. So, that part bent, which in turn froze the mechanism and made it impossible to adjust the seat. Being a tinkerer, I looked at it, figured out the problem, took the seat apart, pulled out the pin, and hammered it back into shape. It worked, for about one and a half sessions, then bent again. I immediately, like the first day I had it, contacted Pleny, who had said to contact them and give them 24 hours to respond. I got the cycle on a Thursday, contacted them that night, waited for Friday, then on Saturday, not having heard anything, I sent a second email requesting help. Monday came, then Tuesday. No response. I contacted Amazon who got on it quick and offered me a refund, but I didn't want a refund, I just wanted one replacement part. I was actually thinking about taking the bolt to a machine shop and asking them to manufacture me a new part but way beefier, but then I though "WHY", why give my money to a company that can't even take the time to respond? I sent a third email on Tuesday night giving the company till the 26th of August to respond. I checked my email, checked my spam folder, and nothing. I have had defective products before. In some, the defect was so small that I was able to tinker around it and have a great product. In others, the company, or Amazon responded quickly and resolved the issue. I have not, at least in recent memory, had a problem where the defect was so fundamental to the functioning of the product, and where the manufacturer was so unresponsive.I see that this product has over 2600 review and averages 4.4 stars, which is why I bought it. I guess all I can say is that if you are anywhere near the maximum weight limit, that this product may not be for you. Again, I may have just received a defective bolt, but the lack of response from the company was a bridge too far for me. If a company truly stands behind their product, then they will do what they can to make a satisfied customer. Shipping out a half pound 8 inch long bolt with locking pin, does not seem too tall an order, nor does answering an email. I really wanted to like this product and give it a glowing review, but that was not my experience with the product or the manufacturer. Now I have to take it apart, pack it up, and have it shipped back for my refund. At least Amazon is on top of it.Hope you found the review honest and helpful. I often see angry reviews because a product came broken. I know that things happen in packing, shipping, delivery, etc... and I will often think, "that person is just frustrated" as I don't see whether they asked the company for any redress. Well, I did, and to this day, no response. I cannot recommend this product, especially to larger people, based on what I think is possibly a defect, but also likely a serious design flaw. If you are in the 200 pound or below range, then this may work for you.This is a great bike for somebody who is starting to try to get back into excising. It’s definitely not a permanent, or perfect bike. I am currently struggling with not really being able to stand cycle on it, which is a bummer. And the handle bars do not match in size which is strange. Other than that, it’s not bad it’s just not exactly awesome!Very good for my need. Doesn't take up much room. Used everyday for the first 4 months for my back problems instead of paying for P.T. Just need to be more proactive in using it more lately. I recommend it to anyone that prefers not going to a gym and/or with similar physical problems.I've had this bike for about a year and a half and while it's not very glamorous, it does what it needs to do. It's holding up decently well aside from a little bit of noise sometimes. It was pretty easy to set up on my own, and came with all the tools needed to do that job.Recently, my cat chewed through the wire that connects the display to the internal stuff for tracking, and the seller quickly replaced the part for me for free with no questions asked, even though I've had the bike for over a year now. Very nice customer service!This is a great exercise bike, easy to put up, easy to store, I would highly recommended it,
