Keiser M3 Review

The Keiser M3 is a relatively high-end indoor cycling bike. Though it may look quite unimpressive at first glance, this indoor bike was not built to be flashy. Instead, most of its qualities are hidden away in the sturdy frame. If you’re not convinced this indoor cycle is worth the price, perhaps our Keiser M3 review will convince you.

Keiser M3 Indoor Bicycle Main Features

The Keiser M3 is a very reliable piece of fitness equipment.

The Keiser M3 features a small computer which monitors drip distance, gear resistance, trip time, heart rate via wireless Polar monitor, kilocalorie expenditure, watts power output, and RPM.

In addition to this, Keiser spinning bikes are easy to install and they have other benefits such as a Fitness Magnetic resistance seat (adjustable in four ways), quality-tested engineering, silent operation, adjustable and portable pedals, compact footprint, and a durable construction.

Not only that, but the Keiser M3 can put up with a lot. It is a semi-professional indoor stationary cycle. For this reason, you may want to consider how often you are going to use it, and how intensely. Considering the fact that this model tends to be more expensive than others, the Keiser M3 might be better suited for advanced trainers, who need a bike that can handle a lot of strain. Otherwise, if you’re not ready to commit to a rigorous workout routine, the investment might be a bit much.

Additional Info

In this section of our Keiser M3 review, we will be looking a few things you should know about the Keiser M3, such as how to maintain the Keiser M3 in peak condition, and what workout routines you should try out on this indoor cycle.

Maintenance Advice

The Keiser M3 does not require special maintenance. To ensure your Keiser cycle is in peak condition, you should check that all nuts and bolts are still firmly screwed in place. You should also wax the areas that come in contact with sweat. Waxing these areas about once a month should be enough. It’s also advisable to lubricate the adjustment handles monthly as well.

Warranty and Guarantee Information

Like all Keiser fitness products, the Keiser M3 has a 10-year warranty for the frame, 3 years for the moving parts and 90 days for the upholstery.


The Keiser M3 does not come with any accessories. However, you can purchase a mat to protect the floor. There are also special maintenance oils and gels you can purchase together with your Keiser M3. It’s good to keep them at hand, to maintain your bike.

Recommended Routines

As mentioned, the Keiser M3 is the type of fitness equipment you can really push. However, if you are a beginner or haven’t trained in a while, you shouldn’t try that. Even though the bike itself might be able to take it, your body might not.

In the beginning, it’s best if you keep your training sessions short. You can start off with a light pedal for about half an hour, and then move to more intense resistance levels. However, if you decide to increase the intensity of the training, make sure the shorten the duration of the exercise. As time goes by you, gradually increase the duration of the workout sessions, to a point in which you feel the burn, but not the strain.
