Product Description

Product description

Keiser

Amazon.com

The result of more than a decade of cycle development, the Keiser M3 is like no other indoor cycle you've ridden before. Keiser scrutinized and quality tested every single component of the M3, from the top of the comfortable handlebars to the bottom of the rock-solid base and everything in between. The centerpiece of the M3 is its eddy current resistance system, which offers infinitely adjustable resistance. This creates a vigorous, challenging workout along with a remarkably smooth, whisper-quiet ride. In addition, the cycle is built to last, as the resistance system doesn't wear and is virtually maintenance-free. And to keep you comfortable throughout your ride, the M3 includes a four-way adjustable seat (up, down, forward, and backward), dual-position comfort handlebars, and adjustable Shimano combo pedals.

The M3 is also equipped with a sophisticated computer system that tracks your rpm, power output in watts, kilocalories, heart rate, pedaling time, resistance, and trip distance. Other features include a gravity-based water bottle holder, an anti-slip belt, and a smooth resistance shifter. Designed with the needs of fitness clubs in mind but portable enough for the home, the M3 carries a three-year warranty.

Used Keiser M3 in great working order.

Used Keiser M3 in great working order.
Ok, so far this is a great spinning bike, it took about an hour to assemble ( with out instructions). Assembly was simple and straight forward. The computer was initially not functioning, I opened it up and reconnected a loose contact which fixed the problem ( see images). The bike works great! As indicated by seller the bike has cosmetic imperfections, wear from use and a bit of rust, but nothing serious nor has any of this impaired function. Delivery took about 6 days through FedEx , the box was intact and the bike was stable and well packed. So, so far so good. I'll update review in future as I begin serious workouts.

I acquired my model from Amazon's Marketplace. My model was one returned from a lease. It arrived expeditiously to my home in 3 days on a pallet.

Opening the bike from the wrapping took only a few minutes. I reconnected the electronics, adjusted the height of the seat and the height of the handlebars, and I was ready to work out. First of all, this bike doesn't need an outlet to plug into the wall. The LCD display is powered by batteries. The footprint is quite small and fits in the tightest of spaces.

The seat is extremely comfortable and feels like a memory foam. The saddle is adjustable in height and in the forward and rear position. The handlebars have a durable foam padding allowing various hand positions whole riding, and is adjustable in the vertical plane. The pedals have adjustable straps and are always set in the pedal forward position for easy mounting, and dismounting. The resistance shifter is smooth and easy to change in increments.

The LCD computer has distinct letters with excellent contrast. It's only limitation is that it doesn't have a backlit screen but it is also an advantage due to excellent battery life. Cadence (in revolutions per minute), power, heart rate, elapsed time, and trip distance are monitored. This is compatible with a Polar heart rate strap so that holding onto handles is not a necessity, like on lower technology equipment. In fact there is no alternative method of measurement for determining heart rate.

Resistance is by an Eddy Current Flywheel which has a smoother, quieter ride. This is so quiet, that I can easily watch a television show without having to turn up the volume. There are 24 levels of resistance which can be determined on the LCD readout.

Overall, I'm very pleased with my purchase. I have tried numerous upright indoor cycles, and this is the quietest, smoothest, easiest to use system with a small footprint to save precious indoor space.

Whether you're a cyclist or a spinner, this bike will suit your needs. It's an outstanding cycle and one of the best available.

Highly recommended!!!!

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.

5.0 out of 5 stars You get what you pay for...
Reviewed in the United States on June 8, 2012

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.

This is the worse experience I have ever had with amazon buying a used product which amazon do not have a complete control. The M3 Keiser that I bought was a total crap. Rusty frame, bearing shut, console not functioning properly, missing screws, rubber stabilizer under the frame was torn and rusty screws, torn seat cover. It was a disaster and and rip off.
