Design & Functionality

There are fantastic indoor bikes on the market and the Keiser M3i tops the list. The steering wheel mounted on the back, the aerodynamic design and the bright colors will surely please everyone.

The handlebars themselves offer the user four different grip positions to adapt to riding styles. But the eddy current magnetic resistance system directs the functionality of M3i ensuring a smooth transition between the “gears”.

Bluetooth App Connectivity

Although many older reviews claim that the only downside of the Keiser M3i indoor bike is that apps cannot be accessed, it appears that this has been fixed. It appears to be able to work with the GoInd application, an application specially designed for indoor cycling. This app collects and stores your training data so you can track your performance over time.

You will get a easy-to-follow and highly illustrated manual for assembling this M3i indoor bike. Having said that, you will require a little more assemble with M3i than most other cycles. For example, you will need to connect the steering wheel, the adjustment pillars, the handlebar, the stabilizer bars, the saddle, the pedals and the console. In addition, you have to do everything with your tools, since they are not provided. Overall, the assembly process is simple and should take around an hour.

Other Considerations:

Although the computer displays training data and allows you to download it via applications, Keiser M3i does not offer any pre-programmed training. This is not a problem, and most people do not even care because they are happy to make their own or watch a video online. Scheduled workouts are great motivators to help you push yourself for a more intense workout. If this is something you are looking for, there are many cycles in this price range that offer scheduled workouts. On the other hand, many people do not need scheduled exercises and simply do their exercises at home while listening to music or watching TV. You can even find complete Spin workouts on YouTube like the one we have shown below in this Keiser M3i indoor bike review.

Though expensive, the Keiser M3i is designed thoughtfully with high-quality materials. It delivers an awesome indoor cycling experience you’ll be hard-pressed to find anywhere but a gym.
