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.
Our Top Magnetic Indoor Cycles
Below we have created a list of our top magnetic indoor cycles. Each cycle passed a rigorous comparison that examined its features, quality of construction, and consumer ratings.

What to Look for When Buying a Magnetic Indoor Cycle
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.
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.
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.
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.
