Keiser m3 plus indoor cycle review

Keiser m3 plus indoor cycle review 2021

As our spin bike reviews would make clear, a front flywheel and brake pad resistance mechanism combination is what drives most of the premium products, leading many to consider these to be the ideal features to look for when purchasing a spin bike. For once, this is not entirely fallacious, since a unit with a rear flywheel and a magnetic resistance assembly would either prove to be extremely weak or conversely, reliable but costly.

Quite surprisingly, the Keiser M3 Plus Indoor Cycle Stationary Indoor Trainer Exercise Bike 2021 offers just such a combination, along with a range of other interesting core features, in a price bracket generally reserved for brake pad resistance bikes. Knowing Keiser, the answer to this intriguing pricing would probably be a unique design. The only way to find out for sure though is through a detailed review.

Ease of Assembly

Like other products from Keiser, this unit comes with the mainframe and flywheel already assembled. Allen wrenches and washers have been included in the package to allow users to complete the assembly in less than half an hour while working alone. The console takes a little longer to attach though, and users have commented that one needs to be careful with the attachment of wiring.

Build Quality and Design

As expected, the Keiser M3 Plus Indoor Cycle Stationary Indoor Trainer Exercise Bike 2021 comes with a toughened steel body that can withstand user weight of up to 300 pounds, making it one of the most accommodative machines in the market in this respect. Unlike other companies, Keiser has chosen not to apply anti-corrosion paint, instead of creating the device with alloys that are naturally resistant to corrosion. This provides the unit with a natural look while safeguarding it against sweat/water.

Coming to the design, we find that Keiser’s innovation translates into a rear flywheel construction. The rear flywheel is closely connected to the pedal and belt drive mechanism, which allows the magnetic system to work in the most congenial conditions. Because of the somewhat different design, the shaft acts more as a counterweight than a weight distributor, and it does this well by virtue of being thick but not overly so. Combined with the availability of a console, these make the product somewhat heavy but extremely smooth in function.

Ease of Use and Comfort of User-Operated Parts

Though costly, we’d mentioned magnetic resistance as one of the key features of the best spin bike to look out for, and vindication of our faith in it is provided by the fact that once the resistance has been adjusted using a simple lever, the workout is smooth, consistent and extremely comfortable. Since the metrics can be viewed easily on the console, one also knows just how much more one has to work out in order to reach one’s goals, and this helps make the workout far more accurate than anything offered by non-console devices.

Along with accuracy, the unit provides sufficient modifiability and comfort. In terms of the former, it is notable that Keiser M3 Plus Indoor Cycle Stationary Indoor Trainer Exercise Bike has handlebars that can be raised in height, and a seat that can be moved horizontally and vertically. While the movement is fast and accurate, some users have complained that the lack of a fro/aft movement option and the fact that the handlebars tend to angle towards the user more when the height is increased, make operating the unit somewhat difficult if one is taller than 6’4”.

Moving towards comfort, we find that the seat is adequately padded, while the handlebars come with the easy-grip rubber covers that Keiser is recognized for.

Lastly, the pedals come with a q-factor that matches the ideal median of the best spin bikes in the market, and thus allows users to enjoy ideal energy distribution and adequate momentum transfer from the pedals to the flywheel. The pedals themselves are large-sized and tend to be compatible with common toe and ankle straps for those who feel that their legs are slipping off the pedals or are larger than the average user’s toes/feet.

Internal Parts and Operation Mechanism

Keiser M3 Plus IndoorA rear flywheel has to be lighter than the front one because the shaft acts a counterweight to the flywheel. This fact is borne out by the Keiser M3 Plus Indoor Cycle Stationary Indoor Trainer Exercise Bike , which comes with a somewhat lighter but larger flywheel that is uniquely suited to this design. Made of heavy metal, this flywheel is capable of ensuring the stability of the unit as the user moves faster and faster.

Connected to the flywheel is a belt drive that has been adapted to the needs of a magnetic resistance system. This drive, which is a direct drive, is short due to the proximity of the pedals and the flywheel and this makes it ideal for transferring the user’s kinetic energy into electromagnetic energy and back to kinetic energy. Despite these changed environs, the belt drive itself is extremely sturdy and can survive many harsh workout sessions.

Moving onto the resistance system, we find that the inclusion of magnetic resistance makes the workout extremely smooth. Transition between resistance levels will be extremely fast, even if you are changing the resistance levels again and again. Since the Keiser M3 Plus Indoor Cycle Stationary Indoor Trainer Exercise Bike offers 25 resistance levels, such transitions can ensure one’s movement from basic to professional level workouts.

Lastly, the unit comes with a backlit console that allows the user to check metrics quickly and so modify his/her workouts accordingly. The console is large, and given that the metrics cycle through (if the option is enabled), it can easily be an USP that differentiates it form units like Sunny Health and Fitness SF-1002.

Warranty

The Keiser M3 Plus Indoor Cycle Stationary Indoor Trainer Exercise Bike comes with a three year warranty on parts.

Pros

  • Excellent design that can support up to 300lbs user weight.
  • Multi-directional seat movement, seat and handlebars well padded.
  • Pedals come with a decent q-factor.
  • Flywheel is light but serves its purpose well, providing adequate stability.
  • Magnetic resistance allows for smooth transitioning between difficulties.
  • Backlist console for easy viewing of metrics.
  • Good 3-year warranty on parts.

Cons

  • No provision for bottle-holder or MP3 holder.
  • Handlebars cannot be raised in fore/aft position (though upcoming/prototype versions ostensibly possess this feature according to some users).

Conclusion

Keiser chooses to defy the average by design, and so we find that contrary to what we see in spin bike reviews, a unique structure has managed to offer so many features in such an excellent combination that it becomes difficult to criticize the unit for either functionality or innovation. With the inclusion of a simple and easy-to-read console and the excellent warranty provided, these features allow the Keiser M3 Plus Indoor Cycle Stationary Indoor Trainer Exercise Bike to be counted among the start contenders for the position of the ideal spin bike for those seeking a magnetic resistance unit or otherwise looking for a bike with smooth and intuitive functionality.
