[UPDATE]: I've had my FitDesk 2.0 for over a year now and I thought I would add to my initial review (found below).Build Quality: Overall the FitDesk seems well built. I've seen some competing collapsible exercise bikes that seem to be virtually identical to the FitDesk in terms of the stand, seat and mechanism, so it would seem that this build form is very popular. That being said there have been a few issues with the bike. As I mentioned in my original review, one of the support arms for the desk was improperly machined, which prevented the tightening screw from being able to engage and hold the desk in place. I contacted Fitdesk and their customer service was incredible. They shipped me out a new support arm (no need to send the old one back) which I received in just a few days, and that corrected the problem.Another issue, and the one that I consider the FitDesk's biggest problem, is the plastic housed computer that relays metrics back to the rider. It is not built to the same level of quality as the rest of the desk. To start with, the simple black LCD seems cheap and lack-luster compared to the rest of the bike (which generally has a sleek and modern look). Also, the information that the computer display, (while the numbers you would want so know), is presented in a way that is haphazard and not clear. You have to see where the small lcd dot is in relationship to some stenciled lines on the plastic housing in order to determine which metric you are currently seeing. It is difficult to select just a single metric without the bike continuing to scroll through the others. The button to reset the stats, such as ride time, or calories burned, does not work at all on my unit. I have to remember what time I started at and then do the subtraction as I ride to figure out how long I have been going. (This can be somewhat solved by removing the batteries each time you ride, but who wants to do that?). Lastly, because the plastic housing is somewhat cheap feeling, and because of the way it is mounted, one must be incredibly careful when folding and unfolding the Fitdesk. I am a big guy, and pretty strong, but I find that it can be a little difficult to unfold the FitDesk without it wanting to slam open. The first time this happened, the force caused the computer housing to completely snap off. I super-glued the pieces back together, but it doesn't really stay on the metal tab very well and it looks awful from the backside. I would suggest removing the computer every time you fold or unfold the bike to be on the safe side.I found the massaging roller to pretty gimicky and in the way of typing so I removed it.The plastic tray under the desk doesn't slide in and out all that well and the desk itself doesn't slide on its rails in a smooth or consistent manner.\On to the positive!I still absolutely LOVE my FitDesk!!! Given its relatively inexpensive cost, I think it is a great product! I still feel like the body mechanics are a little off for someone my height (6'4"), but other family members who are less gargantuan do not have this issue. The pedaling mechanism is smooth as butter and very quiet. I can exercise when others are sleeping or watching television without being disruptive to the household.I think it is quite attractive. It's design reminds me of the turrets from Portal 2 or the space drones from Oblivion. It would seem right at home in the corner of an Apple Store. I don't have space issues at my home, but I can imagine this would be a fantastic piece of equipment for someone living in a small apartment or the like. When it's folded up it takes up very little room in a closet or the corner of a room. I actually leave mine setup in front of a picture window and feel alright doing that because it is quite nice looking.The pedals no longer get loose as they did when I first started using the bike, and the pedaling action is incredibly smooth. It is easy to change the resistance on the fly with the dial and because it is a magnetic resistance system there are no harder portions in the pedaling motion. Ever part of the cycle requires pretty much the same amount of force which I find is much easier on my knees than other bikes.I love being able to have my laptop on the desk and write while I cycle. I find that both my technical and creative writing flow much easier when I am exercising, not mention the time saved by multi-tasking. Sometimes writing can be a chore for me, and for that matter so can exercising, but I find that when I am on the FitDesk I am distracted from exercising pain or exhaustion by my focus on my writing, and conversely, I find that I don't burn out on writing as quickly because I am physically engaged. It is a nice symbiosis of action!Aside from the things I mentioned above, I have seen no issues with degradation of fit or finish with a year of use.I am looking to years of additional use from my FitDesk. I don't think you can go wrong purchasing one unless you are hoping for a commercial grade product.[Original Review]I am fairly pleased with my Fitdesk. It did have a problem when it arrived, one of the threaded holes for the desk had not been machined properly and the desk wouldn't secure. Fitdesk customer service was incredibly speedy in mailing me a new rail and that fixed that issue. A++++ Customer service for sure.A couple of things to keep in mind though. I am 6'4" 230 lbs.... so of course I used the extender for the seat.... even with the extender and the seat all the way up, the fit isn't that great in terms of body mechanics.... I have to really focus on not running my knees into the bottom of the desk, and the angle of legs to pedals just feels a little off.Also, the pedals come loose after every 30 minute session. I just keep the hammer and the wrench with the desk now as I have to bang on it every time I use the bike to get them tight again.Overall, I like the bike. For the price it seems pretty well made and nicely thought out. I think somewhat smaller people will like it even more than I. The reason I bought the bike though was to stay active while I write and it definitely satisfies that requirement.After comparing the FitDesk 2 and 3, I just got the 2, as there did not seem to be any updates that would make the increased price worth it for me. Below, I've broken down my assembly experience, pros, and cons:ASSEMBLY Took an unpleasant 45 minutes to put together by myself. 100% use your own socket wrench (1/2). A 15mm wrench would be helpful, too. I ended up using the provided allen wrench and screwdriver form the kit, because the cheap hardware started to strip my own tools. The instructions were relatively clear, but were missing instructions for some of the pieces. The booklet also advertised an app I could download for installation help, but I'm not about that life. Why an app that I have to download and put on my phone?Some of the materials were not mentioned in the instructions. For example, the FF knobs were nowhere on the manual, but were pretty easy to figure out where they went when I noticed they were leftover and the tray was all wobbly. Wear junky clothes when you assemble it. The provided pedals were oily and streaked on my pants as I put it together.PROS-It is what I wanted. A bike desk I can pedal at while working. I've been doing it 1-3 hours/day.-The flywheel is quiet. The very small amount of noise it makes is rather pleasant and constant. It has become a quiet white noise in the back while I work.- I don't have any issues actively working (writing) while on it, except that I can either write or have back support, but not both. If I'm watching something, then I can lean back for support.- The resistance is decent. The top resistance is similar to what you might encounter while working at about 75% of your max in a spin class.- It is unique and fills a niche. There are not many options for something like this out there and I'm glad it exists.- The desk height is good. Before I got it, I was afraid that the desk was going to be way too low and i would be craning my neck down to see my screen. However, that is not the case. The height is good and I am almost at eye level with the screen.- It is nice that the resistance band is there. I really don't use them very much, but it is nice to have them there if i feel like doing something with my hands.- Price. I thought the price for a 2 was fair. It wasn't great, but pretty good.- I like the cumulative odometer that shows all miles over time.CONS- Uncomfortable. It is not as customizable as I need it to be. I am 5'6" and have 27" arm length and relatively short legs. Even with the seat on the lowest setting (without the extension), back rest on the lowest setting, and the desk as close to me as possible, I can't have both my hands on my laptop keyboard AND my back in contact with the seat support. I can't imagine how this bike would be useful for someone shorter than me and would not recommend it if you are on the shorter side (even though it says you can use it at 4'10"). It makes me wonder if they did any product testing with a bunch of different body types (tall, short, long legs, short legs, etc) or just taller people with longer limbs. I want to be able to move the desk closer and the seat forward more. I also want more control of the tilt of the desk to make it more ergonomically sound.- Seat is particularly uncomfortable. I bike a LOT (road, travel, commuting, and stationary at the gym) and the beach cruiser style with the higher back lurches you forward and puts your weight directly on your butt bones (thus negating the cushioning) or pushes you forward all the way so that your weight is on your inner thighs and crotch. Your butt will go numb in twenty minutes on this seat. I would like to be able to tilt the seat slightly back into a more neutral biking position (and be able to slide the seat forward and back to adjust where the weight sits), but it is bolted in place.- some quality issues with provided hardware, as mentioned above. Screws and bolts are cheap and stripped both the hardware and the tools. I used my own tools for some of the time, as provided wrench is slightly too big for the provided bolts and leads to slipping/swearing. However, I went back to the provided tools when the hardware began to strip my power screwdriver.- I'm not sure why they bothered to put a calorie counter on the computer, as it laughably inaccurate and overestimates calories burned by 30 to 50% (i.e. says 400+ when should be closer to 130)Overall, I use it and I like it, but I am a little worried about the long term effects of using equipment that doesn't quite fit me perfectly and that I can't adjust to make as ergonomic as possible. You have to be very careful about your own posture and the way you are situated on this bike, as the bike is not going to assist you. If it were just a bike, I would return it because of a bad fit, but I'm willing to put it with it for the benefits of being able to bike while I'm working. It is a good start for a great idea, but just needs a little more design work to be truly great.--EDITBig warning for the men AND women wanting to use this. Sitting on a bike seat, even the wide one supplied with this desk, can absolutely cause erectile dysfunction for men and general decrease in sensation in the clitoris and vagina for women. I was getting numb genitals and having to get off and walk around frequently. Erection quality and sex drive since getting this product have plummeted.. yes, well after getting off the bike for the day. It got to a point where I considered seeing a doctor until I put 2+2 together and stopped using this desk. A few days later my ED was significantly improved but not 100%. There is a possibility of permanent nerve damage however I think I caught it in time..If you use this, PAY ATTENTION to your genitals. DO NOT let them go numb and if they do, cease use immediately. You may need to sit differently on it or restrict hours used. Manufacturer should put a clear warning in place before someone gets permanently injured and starts a lawsuit. If you plan to spend long hours on this desk then make absolutely sure you configure it and sit so that your bones directly support your weight rather than nerves and arteries.--EDIT #2All problems resolved within a month. Just take care to sit on it properly and if you get sore then take a break rather than shifting the weight around to a spot that isn't sore.-- Original review:If you are like me and are constantly bouncing your knees, getting up to pace around, just generally feeling restless and you work a desk job.. This is for you! Given the choice to pedal or not to pedal.. I am always pedaling. Never thought I'd be able to make a desk job into something healthy and active. Also it really helps my posture but without feeling forced or having to think about it. Super comfy but for long hours needs a gel seat. Also the extender is a must for mouse+keyboard.March 2018 Update: Bike completely broke while using it. Useless. What happened was (from my inspection once I opened the gear case) is that a washer went bad and this was holding a pulley in place from what I can tell. Gradually this just came completely off rending the tensioner useless since the belt cannot be used. The pedals run with zero resistance now so its pretty much a clothes hanger. I'm ordering a replacement but from a different manufacturer as I am sick of Fitdesk's quality issues.Jan 2017 Update:I actually bought a 3rd bike but not as an addition. Instead it was a replacement for the 2nd bike that I bought and installed at home after Amazon said they would refund me for it's belt shredding to pieces after only a month of use. Fitdesk had said that Amazon UK were responsible for all UK sales and Amazon UK indeed agreed to refund me. It was just a hassle.Here's the surprise though: this 3rd bike came with pedals with screws that were too small for the cranks! I don't know how this happened but luckily I had a small unused under desk bike that I scavenged for its pedals and that I am now using but thins was such a strange experience. Reading the reviews here and on the US site it seems to be chronic so buyer beware.This is still a great product when its working and I still recommend it but am lopping of a star here for all the hassle. I am also attaching photos of the premature damage to the 2nd bike.===========Original review:I rarely rate anything five stars but I will do with this product since when I'm using it I'm always surprised how it keeps me active during time when I would have been most likely sedentary at my desk or couch doing work. It doesn't interfere with a lot of my work either. Measuring with Apple Watch Activity App shows that I've burnt 270 'active calories' in an hour (ie. excluding normal sedentary calories that would bring it up to around 380/hour if you compared to your typical gym cardio machine). I'd also add this is on the 4 setting on a scale of 1 to 8 that feels quite easy to me. My fitness level is above average but nothing exceptional.i wanted to take off a star for how long it took to assemble but then that's just one hour one time for something that works brilliantly. i think i read somewhere that amazon has a product assembly paid service and this is where i'd have wanted to use it. if you have the time then great but if you're a busy person then assembly can be a drag if you want it done carefully.definitely a great way to build fitness habits for people who are too busy and work out of home. at least if you miss your dedicated workouts you've still been active. i will update in a few months if i have more to share.Great for exercising whilst working! Not too hard to assemble, comfortable (would be slightly more awesome if you could bring the table part a little bit closer but that's not a big thing for me).I bought this product a year ago hoping it would encourage me to get more exercise. Over the last 12 months, I've cycled 686 miles, the distance between John O'Groats and London, and have definitely seen an increase in personal fitness. I cycle while working from home, while watching Netflix, and while listening to podcasts. In the past, I used to get discouraged from exercising by the bad weather outside, but this bike has meant that I've been able to continue to exercise even when it's pouring outside. I find the seat really comfortable (unlike the pointy and hard seats of some other exercise bikes) and the desk portion allows me to use a laptop at the same time, which reduces the tedium of cycling. Despite a year's heavy use, it's still going strong. If you're looking for a reasonably priced but reliable exercise bike, look no further.This is a great product and a very necessary one. It has served to eliminate the backache I suffered after being seated in front of a screen for long hours. I use it on a daily basis.A couple of points for Fitdesk's future consideration and to improve an already good product : the desk top wouldn't need to be a lot bigger to accommodate a mouse, it would save on having to buy the extensions at supplementary cost. A rapid release for the desk top would have been welcome too, for storage purposes.I had a problem with the bearing which broke but Fitdesk were wonderful, they sent me a new main frame very rapidly and their service was fast, courteous and friendly. I wasn't without my Fitdesk for long.
