Best Magnetic Spin Bikes & Indoor Cycles

The technology for indoor cycling bike design continues to expand. One of the best introductions into this market is the development of a magnetic resistance system. We have compiled a detailed list of the best magnetic spin bikes and outdoor cycles to help you make an informed decision on which model would be best for you. 

Benefits of Magnetic Resistance vs. Friction Resistance Cycles

Indoor cycles include either a magnetic resistance or friction resistance system. A magnetic resistance system uses magnets to change the resistance. The magnets, which straddle the bike’s metal flywheel, either move closer or farther away from the flywheel to alter rider exertion and resistance level. A friction resistance cycle includes fabric pads or leather straps that apply pressure to the spinning flywheel to adjust resistance. Below is a quick comparison of the benefits magnetic resistance models offer in contrast with friction models.

Best Value: Joroto X2

Price: $439.99 – 4.5 out of 5 Consumer Review

This AV type frame includes a 35-pound flywheel and a six-magnet magnetic resistance system. 

The Joroto X2 is a belt-driven cycling bike that is affordable and well made. Despite the affordable price tag, this bike also includes tremendous value. With reviews such as “this bike is absolutely fantastic” and “great bike at an amazing price with awesome customer service” it is no surprise it received a 4.5 out of 5 consumer rating.

One feature that is unique compared to other commercial-grade spin bikes is the wider soft seat. Most bikes of this type include a narrower competition saddle and are often found to be less comfortable. The four-way adjustable handlebars and seat placement allows riders of various heights and torso lengths to find a comfortable riding position. The digital monitor will enable cyclists to track their progress in real-time by displaying cadence, time, distance, and calories burned. This option does not include Bluetooth© connectivity.

Honorable Mention: Sunny Health & Fitness SF-B1805

Price: $599.99 – 4.6 out of 5 Consumer Review

The SF-B1805 offers a 4-way adjustable saddle and handlebars. It includes a 44-pound flywheel and is belt-driven.

The micro-adjustable resistance provides a quiet and smooth ride upon the Sunny Health & Fitness Bike 1805 earning an honorable mention for our list. This quiet belt-driven model includes a heavier front flywheel weighing in at 44 pounds. This weight will provide a smooth ride and is still lower than the suggested max, a 50-pound flywheel. It also includes toe-cage pedals for those riders that do not have or want clip cycling shoes.

Priced at only $599.99, this model offers users an experience often reserved for higher-priced options. Adjustable floor stabilizers help to keep this cycle in place and decrease swaying on vigorous climbs out of the saddle. Reviewers commented on the sturdiness of this model with comments such as, “I never feel any sort of wobbling, even when standing” and “sturdy and quiet.” It earned a 4.6 out of 5 consumer rating. This includes a tablet mount but does not have Bluetooth© connectivity. Many users were able to purchase a streaming service of their choice due to the savings of buying such an affordable bike model. 

Honorable Mention: Sunny Health & Fitness Synergy

Price: $454.71 – 4.5 out of 5 Consumer Review

This belt-driven bike includes a 30-pound flywheel and performance monitor. It offers pulse sensing handlebars.

The Sunny Health & Fitness Synergy model earned honorable mention due to its high quality at a lower price point. The 30-pound flywheel helps to maintain momentum and allows for resistance to be effortlessly added. One review stated, “The ride is smooth, sturdy, and it’s easy to increase resistance while riding.” This model received a 4.5 out of 5 consumer rating. 

The height range for this bike is a little narrower than other options. Some users between the heights of 5″ and 5’4″ mentioned that they wished the handlebars could be brought a little closer to the saddle. A feature that is not common with traditional indoor cycling bikes are the pulse sensing handlebars. This handlebar feature is most often seen on recumbent models. Your pulse rate is then projected to the monitor and other statistics, including cadence, distance, duration, and calories burned. For those purchasers with a more conservative budget, The Sunny Health & Fitness Synergy bike is an excellent option.

What to Look for When Buying a Magnetic Indoor Cycle

magnetic spin & indoor cycle featured

It can be challenging to know what you should be looking for when purchasing any exercise equipment. Indoor cycling bikes offer an array of differences beyond the type of resistance system. We have created a resource below to help identify what to keep in mind when purchasing an indoor magnetic resistance cycle.

Drive System

A drive system includes the section of the cycle that connects the flywheel and the pedals. The drive systems associated with indoor cycling bikes are either a belt or a chain drive system. A chain drive system is standard in older cycling bikes. These systems mimic the feeling of riding an actual outdoor bike but require a little more maintenance than the other option. Seasoned outdoor riders often prefer this type of system to that of a belt drive. A belt drive continues to increase its presence in the indoor cycling market. Belt drive systems offer a ride that is not only smooth but are also extremely quiet. 

Flywheel

A flywheel is a metal wheel located at the front or the rear of the cycle. This component rotates as the pedals continue to turn. A heavier flywheel is associated with a smoother ride. Aim for a front flywheel that weighs more than 25 pounds and no more than 50 pounds. A heavier flywheel does take additional initial effort to put it into motion. Still, momentum is readily retained, and resistance is seamlessly added with this type of flywheel. Heavier flywheels are located at the front of the cycle. Having a front flywheel does increase the possibility of higher maintenance costs since this placement increases the chance for sweat erosion. Lighter quality flywheels that offer a smooth ride are beginning to emerge into the market. If the flywheel rotates faster than that of the pedal stroke, a smooth ride can be achieved. Lighter flywheels can be found at either the front or the back of the cycle. Cycles with the flywheel located at the rear of the bike are found to experience less sweat erosion.

Apps & Connections

Many added features are enhancing the riding experience at home. Those bikes that include Bluetooth connectivity make it simple for the cycle to connect to your smartphone or tablet. A variety of applications are creating the class riding experience fun at home. Applications such as Zwift ($15/month), Peloton ($13/month), Variis ($40/month), and Sufferfest ($15/month) are providing a unique riding experience that includes motivating instructors and challenging rides. It is important to note that if you take an online class telling you what resistance you should be riding at, you need to understand that the resistance level is not the same across bikes. For example, even though the Bowflex C6 and Schwinn IC4 have 100 resistance levels just like a Peloton bike, a level 5 on the Bowflex and Schwinn is a 25 on a Peloton. Just make sure to check online resistance conversion charts if using an app specifically designed for a particular bike. Your bike’s ability to have Bluetooth© connectivity or an app system included with the purchase is a great benefit. Still, you should not disregard bikes that do not offer these features because, after all, the type of ride that you receive is the most important. 

Bottom Line

A commercial-grade magnetic resistance bike is a wonderful addition to your home gym. They are exceptionally crafted and provide a nearly silent ride making it possible to enjoy a workout whenever the urge hits you.
