Keiser M3iX Indoor Cycle

 

The Keiser M3iX Indoor Cycle is a groundbreaking new entry into the indoor cycling and spinning bikes market.  The Keiser M3iX has the unique Trixter X-Bar handlebar type (pivoting handlebars), which allows you to do mountain biking and hill-climbing without leaving the comfort of your room.

But what is unique about the Keiser M3iX spin bike handlebars is the resistance levels. There are seven resistance levels on Pivoting X-bars that allow intense and relaxed upper body workout. You can adjust the resistance during the ride without stopping or getting off the bike.

Using the Keiser M3iX, you can do upper and lower body exercise rather than just lower body workout, which is what you would do on any other indoor cycles. Therefore, cycling on the M3ix bike by Keiser, you can burn more calories and reach your fitness goals quicker.

The Keiser M3ix handlebars are only part of the unique features of this indoor cycle. Keiser M3iX spin bike has an excellent Bluetooth wireless computer, a sleek style, super smooth ride, and whisper-quiet operation. And the reliability of this Keiser spin bike is the same as the Keiser M3i, one of the best selling bikes.

M3iX Frame construction

The Keiser M3iX features a durable frame, wholly made of steel tubing. It’s composed of two main pieces, the H-type base and the main chassis of the unit. The chassis attaches to the base via four screws, the attachment point being the middle part, which provides the unit a low center of gravity, considerably improving its stability.

The four adjustable levelers enhance the bike’s stability on its front and rear parallel base bars. Each leveler features a rubberized pad, elements which also provide a good grip of the bike onto the floor so that it won’t slip back and forth or sideways with ease.

The Keiser M3iX exercise bike has an entirely black paint finish except for the seat post and handlebar post which have a chrome finish. The paint finish is corrosion-resistant; however, the bike is for indoor use only.

Using it and storing it outside may eventually lead to the corrosion of other parts if not the frame, such as bolts or joint parts which are not rust-resistant.

This Keiser exercise bike isn’t huge compared to other fitness equipment. With the frame fully set up, it’s only 49″ (125 cm) long, and 26″ (66 cm) wide. Also, its highest point reaches approx. 45″ (114 cm) above floor level.

The bike is not extremely heavy but does weigh at least two times more than the average mountain bike. With the frame fully set up, it’s approximately 96 lbs (43.5 kg). This weight adds to its overall stability. However, the bike’s relocation is not too tricky as its front base comes with two large, silicone-rubber transport wheels.

The frame portion between the seat tube and the console mast can act as a step-up pad. Not only that this element can help with entry and exit, but it can also serve as a step-up element for a different spin or cardio workouts which require repeated mounting and dismounting.

Seat

The Keiser M3iX comes with a standard spin bike seat. The saddle itself features a reasonably slim design, with a contoured surface and pretty consistent padding, especially in its rear section. Although it’s designed to provide optimal comfort, if you’re not used to cycling, you may not find it too comfortable for the first few cycling sessions. But since it has a standard connection system to its bar, you can always replace it with a broader seat; compatible versions should be widely available in most bike shops. Also, its comfort is improvable via a gel seat cover.

The seat is four-way adjustable. Its upright bar has multiple adjustment holes while its horizontal slider also offers a few inches of fore-to-aft adjustment. Plus, due to its standard attachment system, you can also adjust its angle a little bit; but for that, you will have to use tools, as there isn’t a knob for its angle adjustment.

M3iX Handlebars

The M3iX trainer comes with the Trixter X-Bar, which is an innovative type of indoor cycling bike handlebar. It features an internal mechanism which allows you to tilt it sideways. This way, you can simulate hill-climbing, and put a lot of focus on the lateral abdominal muscles, as well as the whole core.

The internal mechanism of the handlebar features a resistance system. It gives you the possibility to increase the resistance it takes to tilt is sideways, in case you want to undergo a more intense workout. Its side tension adjustment knob makes available seven resistance settings.

The handlebar offers a multi-grip design which provides the possibility to adopt more than four types of grips. It has two center aero bars and high-density foam grips. However, as opposed to the handlebar on the M3i bike, it is only 2-way adjustable (up-down).

Therefore, the bike can accommodate users between 5’0″ and 6’2″ (153 – 188 cm). If you’re taller than 6’2″, you may not benefit from a complete leg extension. So, if this is the case, you may want to opt for the Keiser M3i.

Resistance

This Keiser indoor cycling trainer comes with an 8 lbs (3.6 kg) chrome-plated and balanced flywheel. Since it doesn’t have a perimeter-weighting, it does offer the aggressive inertia of spin bike such as the Body-Solid ESB250, for example.

However, it does provide a very stable and smooth motion, while the magnetic resistance system delivers quite an impressive pedal tension.

Similar to the BodyCraft SPR, the M3iX has a magnetic resistance system. The brake consists of a magnetic bracket which is near the flywheel. The brake connects via a steel wire to the lever on the handlebar tube. Thus, the bike doesn’t need to be connected to a power source, while the computer doesn’t play any role in the resistance adjustment.

By pressing the lever forward, the magnets’ housing will rotate enabling the magnets to cover a full portion of the flywheel, therefore generating a magnetic field of higher intensity and creating more drag.

Conversely, by pulling the brake lever towards you, 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 wheel.

There are 24 levels of resistance available. The 1-3 gears deliver a light workout, while the top 20-24 levels allow you to perform exercising routines of high intensity.

M3iX Drive system

Like most exercise bikes equipped with magnetic resistance system, this model features a belt drive system. Therefore, its transmission doesn’t require lubrication while the pedaling motion is almost entirely silent.

As I mentioned above, this trainer is for spin workouts. So, just as any other spin bike, it is equipped with an extremely durable 3-piece crankset. The crank arms are made of steel and can withstand users up to 300 lbs (136 kg) during standing up pedaling routines.

The pedals are also no exception; they’re a metallic alloy, featuring toe clips on one side, and SPD clip elements for spin shoes on the other. They also have standard 9/16 threads so you can easily find replacements for them if needed.

In case you’re wondering, pedaling in reverse on this bike is possible. However, you cannot coast on it. When pedaling in reverse, the resistance remains the same, corresponding to the selected tension level. Also, the console continues to monitor your distance traveled, calories burned, etc., when pedaling in reverse.

Computer

The bike includes the Keiser M Series computer. This type of fitness meter features a large, multi-window LCD, which shows several workout metrics simultaneously. The unit’s display integrates LED backlight and has a sensor for it which detects the ambient light levels, turning it on when needed.

The unit’s display tracks watts, kilocalories, heart rate, time elapsed, distance, total distance (odometer), and RPM. The console will swap between Watts/KCal, Trip Distance/Odometer showing each one for 8 seconds on their display section.

The distance can is in either metric or imperial units; the unit will prompt you to select this preference when you first start pedaling. The console also indicates the “gear” or the current resistance setting of the bike.

The bike’s handlebar does not have pulse sensors. However, the computer is Bluetooth enabled and can read your pulse via an HR chest strap transmitter. According to the manual, it should work with a Polar HR chest strap with an H7 or H10 transmitter.

The Keiser M series computer does not have any pre-set workout programs. It requires two AA-type batteries which (are included). It doesn’t have any buttons, so setting it up is done by using the shift lever. The manual will thoroughly instruct you on how to do this. It has a sleep mode to which will enter after 60 seconds of inactivity on the bike, and it starts on when you begin pedaling.

M3iX Assembly & Maintenance

The top frame comes partially assembled. In other words, the resistance system, the crankset, and the belt are pre-assembled to the top frame.

So, for assembly, you only have to attach the central part of the structure to the H-base, then add the flywheel, the flywheel cover, the seat, the pedals, the X-Bar, and the console.

This shouldn’t take more than one hour. The manual offers excellent assembly instructions accompanied by pictures and schematics.

Since it’s a magnetic exercise bike, there’s no wear and tear to the resistance system, so you won’t have to worry about replacing parts there. It’s a pretty much maintenance-free trainer. All you have to do is periodically check for loose bolts and components, and wipe off the sweat from the frame if it’s the case.
