M3i Spin Bike Features in Detail

Bluetooth & Display

Keiser M3i Spin Bike

Technology in cycling seems to get more pervasive with each passing year. Go to any consumer electronics show (such as CES this year), and the chances are that you’ll find many products revolving around connectivity and fitness data to make workouts trackable and more challenging.

The computer can transmit the data wirelessly via a Bluetooth connection to a smartphone and also track and display your workout data.

The screen features an automatic backlight and can display cadence (RPM), Power Output, Heart Rate, Elapsed Time, Gear (resistance level) and trip distance. This data is beneficial when it comes to tracking improvements over time and comparing your efforts.

The bike is compatible with POLAR branded chest straps.

Frame & Handlebars

The M3i uses a V-shaped structure that is easy to get on or off, sturdy and lightweight. The bike can accommodate riders of all sizes with the adjustable handlebars.

The new model features a black color scheme that looks great with the new red wheel rim.

The M3i is constructed sturdy enough for a home-based stationary bike.

The seat and handlebar system is fully adjustable. You’ll be able to make changes to seat height, position and reach.


A lot of the equipment, including the flywheel, is made of stainless steel. It makes the bike capable of standing the test of time, stress and sweat.

The M3i uses a rust-resistant design.

Pedal system

Uses a Shimano SPD style clipless system which allows it to be used with cycling shoes. You’ll be able to stand, sprint, put out power throughout the pedal stroke (just like you would on the road).

The flip side of the pedal features a smartly designed toe-cage so that regular shoes can be used. It also features easy-to-adjust straps.

The new pedal is exceptionally durable and has a long service life.


The bike uses magnetic strength to provide smooth, quiet and linear resistance. It is controlled by a lever just under the computer display.

On either side of the flywheel are two sets of magnets. The lever controls the distance of the magnets from the wheel. The closer they are to the wheel increases the resistance.

Furthermore, a magnetic resistance system has many advantages. You won’t have something continually rubbing against the flywheel to produce resistance like a brake-based system.

Therefore, that makes the bike smoother and quieter in operation and minimizes any wear and maintenance.


The M3i was designed to feel like a road bike to ride. The crank and pedals turn smoothly and quietly, similar to belt-driven bikes.

Also, the belt-driven drivetrain and magnetic resistance add to the smoothness and consistency of ride quality.

Weight, Portability & Assembly

The bike weighs in at 85 lbs. / 38.56 kg. The bike’s full dimensions are: (H)45″ X, (W) 26″ X, (L) 49″.

It’s critical to follow the assembly instructions to get it right.

Some of you may scoff at reading the instructions. These are important.

Adjustments & Fit

The seat-post has multiple holes which allow for fine adjustments. Because the seat height is such a significant adjustment to get right, this fine-tuning ability can make or break the quality of workouts.

The seat post uses a dual-locking system. Once you’ve set the seat height, you want it to stay put, and that’s what this one does. Discovering that your seat-post has slipped can ruin a workout (and may cause damage).


The bike has a well-designed bottle cage.

Final Thoughts on the Keiser M3i Spin Bike

If you’re ready to get serious about indoor cycling, look no further than the M3i. Its popularity in commercial gyms proves that the M3i has the durability and build quality to withstand heavy, frequent use.

Furthermore, it’s the Bluetooth connectivity that pushes this bike over the top regarding quality and workout tracking. If you’re looking to invest in an indoor exercise bike with quality workouts for years into the future, then this makes a significant investment and is currently our #1 recommendation.
