Keiser M3i Features

There are four types of indoor cycles – the upright, the studio, the recumbent and the combination bikes with the elliptical and exercise bike in the same machine. This studio bike comes with unique features:

  • The flywheel – The design of the M3i is totally unique with the flywheel positioned at the back.
  • The V – shaped frame is heavier to lower the centre of gravity for enhanced stability.
  • The 4-way adjustable seat moves upwards, downwards, forwards and backwards to accommodate the user’s height and length of limbs.
  • The 4-way adjustable handlebar – The Keiser M3i also comes with an area adjustment. That is, you can adjust the distance between the handlebar and seat, besides its height and the angle. The design of the handlebar has an overhand front grip, the extended grip and the hook or the middle grip. This design not only accommodates a range of heights but also personal preferences. Furthermore, it offers great support when switching from low to high-intensity workout.
  • Simple seat adjustment pull-pin with height and distance settings. This makes it easy to adjust the distances between the seat and handlebar.
  • The transport wheels at the front base stabilizer. The advantage of indoor bikes is that they are easy to store away or pulled out for a workout. All you need to do is tip the M3i using the handlebar and roll the equipment on its wheels to anywhere you like.
  • Eddy current magnetic resistance system offers 24 resistance levels. The system works on a series of gear changes controlled by a resistance shifter, i.e., the red lever just under the console. The resistance shifter controls the strength of the magnetic field that meets the flywheel.
  • The water bottle holder is a small recess moulded into the frame between the pedals and handlebar.
  • Media tray – To display your smartphone or tablet.

What I Like

The Keiser M3i is suitable for home users and group exercise classes, as the bike comes with labelled height and distance settings of various users simply at a pull of a pin. It has a top-notch design & functionality with the rear-mounted flywheel and aerodynamic design. The eddy current magnetic resistance system ensures a smooth transition between 24 levels of resistance. The Bluetooth App Connectivity with various apps, such as the BKool Indoor and GoInd, help to track your performance over time.

What I Didn’t Like

We can’t seem to find any negatives to review, yet to cover this field; there are no preprogrammed workouts. These are huge motivators to push you to work out beside the price may be steep for some.
