It’s not just any indoor exercise bike though. It has quite a lot to offer in terms of training possibilities.¬†As opposed to many spin bike models, this particular bike features magnetic resistance, and also comes with a fitness computer.

There’s a lot to be said about each and every feature and function of this bike. But before we proceed with this review, one important aspect must be clarified. This is the Keiser M3 Plus, the 2015 version, and still one of the best models for 2016.

Frame

The main material used in the frame of this bike is aluminum, with several parts of steel. The development team has opted for aluminum rather than steel as basic material for the frame, as it’s a highly resistant material to corrosion. The M3 Plus model is a spin bike designed to make you sweat. Evidently, if the frame isn’t corrosion resistant, all the sweat that will drop onto it, may eventually cause damage.

The frame features a one-piece base, letter “H” shaped. The base has tiny leveler “feet”, providing maximum stability even on irregular surfaces. Also, the front part of the base is equipped with silicone wheels, which allows the transportation of the fully assembled bike with ease. The main body of the bike comes attach to the base at the middle via four solid bolts. The whole frame assembly is quite stable, doesn’t move or wobble during intense workouts even with users close to the maximum supported weight.

The base footprint is actually 49.5″ (126 cm) long, and 26″ (66 cm) wide, so the bike doesn’t occupy that much floor space. But with the handlebar assembly and its main post extended at maximum, it reaches 58.5″ (149 cm).

Seat and handlebars

The seat equipped on the Keiser M3 Plus, is pretty standard, similar to any other seat that you will find on a spin bike. However, one important feature regarding this bike’s seat is its fore tom3 pluse - keiser bike - seat aft. adjustability. This particular feature offers the possibility to find the perfect posture for your height. Needless to say, the seat is also vertically adjustable, supplying a distance of 17″ (43 cm) between minimum and maximum setting. Differently put, this bike can accommodate users between 4’7″ (140 cm) and 6’7″ (200.6 cm).

The handlebar for this bike features a multi-grip design, supplying the possibility for various training postures. It’s consistently padded with rubber foam, to prevent palm sores or blisters, and to ensure a good grip even if your hands become sweaty. Similar to the seat, the handlebar can be adjusted height wise. Also, the handlebar assembly is fore to aft. adjustable, which adds to the bike’s possibility to accommodate a wide spectrum of users.

Drive and brake system

This bike features an eddy current brake system, powered by two opposing magnets placed on a rotating housing, one on each side of the flywheel. But since it’s not an electromagnetic brake system, the resistance of the bike is adjusted manually, by pressing the resistance lever on the handlebar post forward, which rotates the magnets assembly, exposing the flywheel to a magnetic field of higher intensity. As opposed to that, by pulling the brake lever towards keiser m3 plus - drive systemyou, it will enable the magnets’ assembly to rotate in the opposite direction, moving the magnets away from the flywheel, and generating less drag. If pushed all the way forward, the lever acts as an emergency brake, automatically stopping the flywheel.

The flywheel of this bike is relatively light, and slim, in comparison to the ones used by other indoor exercise bikes. It’s not perimeter weighted, but since it’s lighter, it doesn’t render a stairmaster feel when pedaling, even when the bike is on a high resistance setting. The drive system features a pretty solid belt, which adds to the smoothness and quietness of the ride. Since it’s basically a magnetic resistance bike, you can also pedal backwards, but without losing any resistance, as you would on a typical, multi-gear bicycle.

The bike’s crank assembly features a rather big pulley, almost the size of the flywheel, also aluminum-made, just as the flywheel. The crank arms are pretty solid, finished with Shimano Combo pedals, with straps and clips for spin shoes. The bike’s Q factor is 197 mm, offering enough space to prevent feet from touching the pulley, and to ensure the optimal pedaling force. On the other hand, this particular Q factor is quite a bit narrower compared with other bikes. The pedaling motion should not put any additional stress on your knees.

Console

The performance monitor supplied with the Kaiser M3 Plus indoor cycling bike is pretty basic, and easy to use. It’s powered up by the movement of the pedals. It indicates values such as RPM, time elapsed, power output, gear, and trip distance. The Power Output value is displayed in Watts and Kilocalories, alternating between the two (8 sec. for Watts, 2 sec. for Kilocalories). The Gear value is determined by the resistance level you set from the lever, the console actually being able to detect 24 gears.

The Odometer function on this console is actually a bit odd. It doesn’t display the trip distance in Km or miles, but something in between. It’s actually a feature designed only for maintenance purposes, actually meant as a usage indicator for Keiser bikes used in gyms.

The console is telemetry enabled, being able to track heart rate as well, via various types of chest straps. Since the bike features a simple eddy brake system, the console doesn’t feature and goal setting functions or preset, resistance auto-adjusting programs. As mentioned above, resistance is manually adjustable.

The console unit features a backlit display, with a sensor that can determine the lighting in the room, and light up the screen if it’s darker. It uses 2 AA-type batteries.

Assembly and Maintenance

The main body of the bike, including seat, crank assembly and handlebar post, come already assembled in the box. All you have to do is attach this main body of the bike to the one-piece base, then add the flywheel, pedals, console, handlebar assembly, crank and flywheel guards, and several other smaller pieces. It’s not very difficult to assemble, and the manual provides comprehensive step-by-step instructions to it. The assembly requires your own tools.

Since it’s a magnetic resistance exercise bike, there’s basically no wear and tear to the braking system, so you won’t have to worry about replacing parts there. It’s actually a pretty much maintenance free indoor bike. All you have to do for maintenance is basically wipe off sweat from the seat and frame after workout, re-tighten bolts in place from time to time if it’s the case, and lubricate the adjustment handles with heavy grease, such as Hydrotex MT-55 or Dow Corning 111.
