5.0 out of 5 stars great & unique exercise bike! January 28, 2009

By Peter

I frequently ride a bike outdoors during the summer, but in the winter when the weather is not as good I often go to the gym to ride the exercise bike. None of the indoor bikes I had ridden ever had the smooth feel of riding outdoors - until I tried the Keiser M3 at a health club. I loved it so much, I bought one for myself for home use (the first time I've ever bought home exercise equipment as an adult), and while I've only owned it now for a short time, it is fantastic. Due to the unique design, utilizing magnetic resistance, the feel is very similar to riding outdoors. It is very quiet and very smooth. So I can spin at a fairly rapid rate and still get my heart rate up. And, though I don't do this much, you can also crank up the resistance and make it as hard to peddle as you would like (it has about 24 "gears" so you can continually increase the resistance to virtually whatever level you would like - what is really happening of course is you are simply increasing the magnetic resistance). This is a first rate bike for anyone who is serious about biking and wants something to use indoors that feels like biking outdoors. It is great exercise and does not feel like the typical gym or spinning bikes.

It was easy to assemble even for someone like me, who views changing light bulbs as a modest maintenance task. In total, it probably took about 30 minutes to set up and required little more than a Philips head screw driver, an Allen (sp?) wrench (which I have for my outdoor bike), and either a pedal wrench (again I have one) or an adjustable wrench that would fit the pedals.

Lastly, I would recommend ordering via Amazon or Keiser directly since some of the small third party sellers do not deliver on time. I would not buy from Indoorcyclingstore....com, who appear to be either terribly managed or are dishonest; we initially placed an order through them and six weeks later we still did not have the bike, but they still had our money.

5.0 out of 5 stars Once I tried it, I *had* to buy it... September 3, 2010

By Peas on Earth

I've been doing quite a bit of research for which bike to buy for home use. I was initially interested in just getting what I have at the gym the Schwinn Evolution. In a store, I was almost sold on the Schwinn A.C. classic or sport, but the seat was very uncomfortable, and I while I loved the magnetic resistance, I wasn't quite convinced by the ride.

Then I found all of these fantastic reviews on the M3. I called around, but it turned out none of the stores that sell them in the area, had them on the floor as demo. Finally, one sales person admitted to me that even though he (and everyone else agreed) thinks it's a fantastic bike, they don't keep it on the floor because their margin of profit on them is much smaller than it is on other bikes.

I didn't want to invest without trying them out, so I called Keiser and found out who our local rep is. Sure enough, he had one we could try in his garage. This is the most amazing piece of engineering I've ever seen on a bike!!! This guy had been with Keiser for 18 years, and knew every detail of what's going on. Basically, they started developing this bike after years of taking losses because they conformed to the price standard in the market, and at that price, could only manufacture bikes that like every other bike, would break and need maintenance. The maintenance cost them too much money, and they got tired of it. Being a small independent company, they decided to do something about it, and the M3 was born. They are ruthless about their price policy of it, even if you buy 250 of those, the discounts are fairly minimal. On the other hand, these bikes require NO maintenance!!!

If you look at their 3 year warranty carefully, you'll see that labor is not included.... I called to ask about that, and they claimed on the phone that labor is not NEEDED, because everything you might ever need to do, is so simple you could do it yourself. Well, my spouse has a strong engineering background (experimental physics), and we inspected every aspect of this bike. They're right. It is TRIVIALLY simple to put together, and there's basically nothing that could break!! If you can handle a screwdriver, you can handle this bike! The engineering is GORGEOUS, someone really put a LOT of thought into the design. And the ride, oh the ride... Smoothest ride EVER! And SO comfortable! Everything from the saddle to the positioning, just perfect!!! The balance feels just right, it's super quite, and most importantly, there are really no parts there that could break, except perhaps the computer. As far as maintenance is concerned, according to this guy, it's limited to cleaning up your sweat from the bike, after a workout...

I should mention, when I was looking at the Schwinns, they offered me the floor model at a ~15% discount. The flywheel looked pretty scratched, basically it looked used. The demo we saw, is the same demo the guy has been using for 5 years, to show gyms, take to shows, show private clients, etc. If he had told me he only unpacked them yesterday, I would have believed him. They looked brand new, 5 years later!

Finally, Schwinn spin bikes division has been sold and resold and keeps moving hands. You really don't know who you're buying from (the Schwinn A.C. are on the Nautilus website - their latest buyer, rather than on the Schwinn site). Keiser is solid, made in the USA, and you know who "their daddy" is... And keep in mind if a sales person tries to sell you a schwinn over the keiser - their margins of profit are MUCH smaller for the keisers, and they usually work on commission.

Anyhow, to make a LONG story short, we bought the bike. It was a no brainer. I'll update my review after I've used them for a couple of months at home, but I fully expect the 5 starts to remain. If you can't find this bike anywhere to try them out before buying, I recommend you call Keiser, and they'll help you out.

*** ADDED A FEW MONTHS LATER *** (Jan 2011)

Now that I've tried these in my pregnant and non-pregnant state, I can stay 100% - I absolutely adore this bike!! I've been using it almost daily. It's SO smooth, quiet, and comfortable - in seated AND standing positions! I don't get the people who talk about wrong fit. I am 5'6", my spouse is 6', and it adjusts to each of us perfectly. Maybe if you're extremely tall or extremely short it might be an issue, but then I bet a lot of other bikes would be too. This is just a very natural ride, the computer is fantastic, and overall, I can say only good things about this bike (and I've tried many other bikes at gyms, including the popular Schwinn Evolution. I *far* prefer this one to any of them!) Read more ›

5.0 out of 5 stars Keiser M3 - Style, Qualtiy and Performance August 31, 2009

By M. Fedder

I ordered this bike from Amazon (Brands Cycle and Fitness) on a Wednesday evening and had it in my basement on Friday afternoon. Shockingly good service in today's world. The bike was well-packed and arrived in perfect condition. Taking my time, assembly took about 25 minutes because I had all required tools on-hand. If you're a directions-follower, you'll need 15mm and 16mm box wrenches, a deep-socket 15mm or 16mm socket, a torque wrench, a 4" socket extension and 15mm and 16mm crowfoot wrenches (see MIT 10 Pc 3/8" Drive Crowfoot Wrench Set- Metric).

As indicated by other reviewers, the Keiser M3 is very quiet; so quiet that my squeaking mountain bike cleats started to annoy me. Shifting the bike involves moving a bar-mounted lever up and down for "gears" 1-24. Lift all the way up and you'll activate an "emergency brake" which stops the flywheel immediately. In reality, just lifting the shift lever to 15+ will stop the flywheel very quickly.

Adjusting the bike to your dimensions is simple and smooth. Unlike most spinners, the lock-down bolt doesn't have a spring-loaded pin that inserts into pre-drilled holes. Hence, you can set the seat and handlebar heights to an infinite number of settings over their entire range. Since my wife and I share the bike, I marked a small black line at my height settings and a blue line at hers. I'm 5'8" tall but have long legs and a short trunk so I was concerned about the nature of the M3's adjustability. Namely, moving the seat and handlebars up moves them away from each other. Look closely at the frame geometry and you'll see what I mean. The good news is that I was able to adjust the bike to a proper riding position for my build....

The workout computer has all the necessary data to measure workout performance (watts, kcal, distance, time, gear) but see #2 below.

Two items to improve the bike:
1) A clutch that permits free-wheeling. Apparently, Keiser did offer this in the past but it wasn't a strong seller so they dropped it from the M3. Here's one vote to bring it back as an option.

2) Add workout programs to the computer. For those of us using the M3 at home (i.e. not in a spinning class), it would be nice to have a few pre-programmed "rides" to call up. Better yet, let us create a program from a riding session and save it.

Bottom line, I love this bike and recommend it highly to those looking for a smooth, high-quality spinner. If you appreciate machinery, the M3 is a true work of industrial art. Read more ›
