Keiser M3 Indoor Cycle Stationary Trainer Exercise Bike

I purchased this bike, because I use it at my gym and know it's great quality. It makes absolutely no noise and the bikes need little to no service over their lifetime. What I didn't know was how outstanding Keiser's customer service is. I had a few issues with my bike that were caused by a poor installation (I do NOT recommend paying to have Amazon's 3rd party contractor come install the bike). I called Keiser and they overnight shipped replacement parts and sent an incredible service person to come replace the parts and fix the installation. They did all this for free (even though the bad installation was not their fault!) and were incredibly friendly and responsive. I love this bike, love the comany's service even more, and will highly recommend Keiser to anyone I know who is looking for a bike :)

There are many positives about this spin bike and only one negative, so I'll start with the negative.Negatives:1. The Cost. For sure, this is an expensive peice of equipment and I can see why it would drive some people away, but I feel the need to tell you what you'll get for your money, which brings us to...Positives:1. The Ride. It's remarkably smooth, quiet, and stable which were the three most important things to me. You can crank as hard as you want on this bike and it never feels...well, cheap, for lack of a better word.As was mentioned by other reviews, it uses magnets for resistance. And apparently Lenz's Law, Focault Pendulums, Bernoulli's Principle, Pythagorim Theorem, whatever. I don't care. What I care about is that when you ride it, it's stupid quiet. You will breathe much more loudly than what the bike will make in terms of noise and so watching TV or movies is very easy. We don't have kids, but if you did, and you were worried about waking them up, don't. You might wake them up with your breathing, but the bike won't with it's action.The other reason I like the magnets is the feel of the ride. With other spinners that use the friction plate to increase resistance, it feels like you're riding a bicycle with the brakes on. I don't like that. I like this one; it feels more like you're riding up a hill.2. The Computer. If you are looking for an objective workout, this is a big deal. For one thing, the "gears" have a digital reading and your time is right in front of you so you can say to yourself "Self, I'm going to go at level 18 for 3 minutes and then drop down to level 15." Your power is also right there, along with calories.This is entirely more objective than twisting a knob and sort of guessing at the resistance. Also, the screen will tell you the average wattage at the end of a ride so you know how strong you rode and have a number to improve on. It also gives you distance...again, you can put a time to a certain distance and improve on it. It's alot easier to get back on the bike when you have a number you're shooting for. I think, anyways...3. The Workout. The reviewer who said he couldn't get his heart rate up is either Lance Armstrong or is trying to impress women with an Amazon Review of a Spin Bike, both of which are incredibly lame (you get that label when you do a Michelob Ultra ad...sorry Lance). I'm in pretty good shape and this bike will wear me the hell out.4. The Manufacturing. Made in the USA. Feel good about buying one.5. The Service. So far, we've had positive experiences with Keiser. When we first got the bike and were putting it together (not too difficult by the way - took about 2 hours and we were taking our sweet time) we thought we were missing a hex-nut. Turned out we weren't, we were just dumb and didn't bother looking on the bolt that it should go on.Anyways, we called up the company, talked to a real-live person, and they sent us a replacement in 2 days, no questions asked. Now we have two hex-nuts. Oh well.All in all, I think this is totally worth the money and I am glad that my wife and I purchased it. We have no semblance of buyer's remorse. I should also tell you that I am 6'2, my wife is 5'3, and we have no problems with adjusting the bike to a comfortable position between the two of us. There are several reviews that have brought up concerns about the design of the bike and angles at which your body will sit - I'm afraid I can't comment intelligently on that but it hasn't been problematic for either my wife or I.What I can tell you with certainty, is that this bike provides the best impact-free, aerobic workout I've ever had.***Update***After 18 months (roughly) of using this spin bike regularly, there hasn't been a thing go wrong with it and it's still providing a great cardio workout. We still have no buyers remorse and I still think you should get one.

I’ve put over 200 on my odometer without any issues. This bike is smooth and quiet. I use the Peloton app and have converted their 0-100 resistance to the bike’s 1-24. Set up was easy. Very happy with this purchase!

Awesome fluid magnetic resistance. Ideal computer, Polar HR monitor compatibility is all I need. Takes getting used to (spinner style) and may not be comfortable for everyone. Wish the handlebars had more position options (closer to seat). Bought used, arrived protected and fully assembled. Great customer service.

This is the one, if you're a serious athlete. I've beat the hell out of these things for years at my gym and finally squirreled away enough money to buy one of my own. I am tickled pink, to say the least! It's pricey, but it' the last trainer you'll ever buy.

Awesome machine. So quiet and so smooth. Also, I literally put it together with an adjustable wrench and a fold up Allen wrench accessory I keep with my mountain bike, which is good because the only other tool I have is a hammer. It took me about an hour so anybody with any tool skills could put it together faster. To be safe I had somebody come by with a torque wrench to double check the assembly, but it was fine. For shorties out there, I am 5' and am able to reach the handlebars just fine without locking out. It might be more comfortable if they were adjustable - but if you don't want to spend the extra 100$ you should be fine.

Extremely happy with this bike! Quiet, comfortable, sturdy, a pleasure to ride. Arrived in perfect condition, packed exceptionally well! The few parts you do have to assemble go together with ease, good instructions! Spend the extra few dollars it takes to own this bike, well worth it, can't emphasize that enough!!!!

I love this bike.... ship very well, strong bike, and easy to put together. You will not be disappointed with this purchase. Made in USA. Love it.
