MagneTrainer-ER Mini Exercise Bike Review

MagneTrainer-ER Mini Exercise Bike

If you’re a busy professional with a demanding career, you probably don’t have the time to head to the gym to sneak in even just a short workout. We know the struggle. But what if we told you that you can workout and work simultaneously? 

With a desk bike, you’re giving your legs the action it needs to promote a more comfortable and productive working session. Not only that, but you can also live an active lifestyle while merely sitting on your office desk. In this review, we’re going to digest the features and specifications of the MagneTrainer-ER Mini Exerciser by 3D Innovations

At a cheap price of less than $400, consumers are wondering if the cost is due to the lack of desirable functions and features. But you’ll be surprised how much the MagneTrainer-ER Mini Bike by 3D Innovations is worthy of a place under your office desk or in therapy clinics. 

Dubbed as the highest quality desk bike exerciser available, the MagneTrainer gives you the capacity to exercise anywhere and anytime, whether it be in the office, while watching TV, reading a book, and more. The LCD display design conveniently lets you keep track of your progress (including speed, distance, time) and lets you easily adjust resistance levels according to your needs. 

The MagneTrainer is bidirectional, meaning you can pedal forward or in reverse direction, enabling you to maintain balance in your leg muscles. Its wide resistance range and smooth pedal motion makes this mini-bike exerciser excellent for physical therapy and can even be used to workout your arms, with its molded hand grips for safe and comfortable hand and feet pedaling. 

Its thin and compact look is unlike most under-table bikes, making it a unit fit for a table with small under-desk space. Even when you only intend to use it for therapy, this unit is one that doesn’t take up a lot of space, making it fit to be placed and stored anywhere. If customer reviews are anything to go by, then this definitely deserves a spot in your top products to have list. 

Now, it’s time to feature just what this product can do. Let’s head over to our review of the Magnetrainer below.

The MagneTrainer-ER Mini Exercise Bike might look simple and conventional, but it’s surely a bang for the buck with its features. Let’s take a closer look.

Patented Adjustable Magnetic Resistance Settings

The MagneTrainer has a very smooth and almost effortless pedal movement both in forward and reverse directions, thanks to its patented adjustable magnetic resistance. The range of pedal resistance is nearly 3 times wider than that offered by other mini bikes. The resistance system can be set to over 170 Watts at 60 RPM or 400 Watts at 120 RPM.

You can choose from a wide variety of resistance options by simply turning the knob situationally positioned in front of the bike. This multi-turn knob was engineered to provide precise and gradual control in setting the resistance, so you don’t have to worry about setting the wrong range. Plus, there’s no limit to the resistance level you prefer, letting you work out your feet and hands with ease. 

High Quality Pedals

Your security should always be your top priority when using an exercise bike. You might be thinking there’s no harm in a mini desk bike, considering that you’re safely seated on a chair. But that doesn’t eliminate the risk of slips and injuries while using a low quality under-desk bike. In this regard, the best choice is always the one with high-quality design and material, especially for safety reasons.

The MagneTrainer-ER completely eliminates the chances of injury with its pedals. They are equipped with ball bearings and heavy-duty Velcro straps that can easily be adjusted to suit your foot or hand size. This adds another layer of convenience because anyone, no matter what their body type, can use it. 

The pedals also work to enhance your workout experience. No matter what you’re using the device for, whether it’s for physical therapy, toning your legs, or adding movement to a stagnant work day, this mini-bike can easily accommodate each intensity through different resistance levels. The belt drive is built to be whisper-quiet, making it great for at-home use, office settings, and even therapy clinics.

Digital Fitness LCD Display

With the MagneTrainer, you can keep track of your fitness goals even as you work. It comes with a digital fitness display that records your speed, distance, amount of time spent, and calories burned. It also has an auto-on and shut-off feature to help save energy and conserve battery life. Despite the bike not being too suited for whole-body workouts, you can still tone your legs and keep track of each small progress made with this design.

Quiet Motion

Unlike other desk bikes that give out loud mechanical sounds while being used, the MagneTrainer is completely silent, which means you can even use it during a meeting without anyone knowing! The bike is equipped with patented touch-free magnetic resistance, dual-pulley and 7 precision sealed bearings, keeping it whisper quiet during use.

Pros and Cons of the Magnetrainer Bike

✔ 20+ resistance settings
✔ Sturdy steel base
✔ 15-inch base to accommodate different size footprints
✔ LCD monitor shows progress
✘ Pricier than other models
✘ Non-slip base not very effective

What People Are Saying About It

Based on the price range and premium material alone, you’ll be hard pressed to find a product that offers this much value. One of the top mini-bikes in the market, this product stands out for its slim base and dual-purpose design. Let’s see if others agree with our review of this mini-bike.

“There are cheaper alternatives, though none match the quality of the original Magnetrainer. It is the smaller touches which make the biggest difference.”
