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.

Price & Reviews Get Holiday Deal

When I first saw the Sole Fitness bike, I was very impressed. It’s got an absolutely beautiful sleek modern finish, and honestly, I think it is one of the best-looking bikes we currently have on the market.

Yes, it looks the part but does it do the job? Well, let’s start with the technology. We have a small data screen on the handlebars, which will give you all your basic metrics such as time, distance, speed, heart rate, RPM, and much more. It is also equipped with Bluetooth connectivity so that it can be used with third-party applications such as Zwift or Peloton. It has everything it needs to keep up with a bike like the IC4 or Bowflex C6.

As far as internals go, it is packing a serious punch with a 48lbs flywheel. Not only does the flywheel give it stability, but it’s also paired up with a magnetic resistance system and is a belt-drive too. This bike is going to be super silent and going to feel incredibly solid at all times, including when you’re in a maximum sprint. Another feature I like about this bike is the tablet mount sticking out the front, which has put it in the perfect position. 

How Magnetic Resistance Works

For magnetic resistance to occur, a few things need to happen, and as you can guess, this process includes magnets. A standard design contains two powerful magnets located parallel to one another with the flywheel between them.

The metal flywheel, which works as a conductor in this instance, spins through the two magnets’ magnetic fields and the force surrounding them. This magnetic field causes a drag on the metal flywheel, which creates an eddy current. An eddy current gets its name from the swirling motion of an eddy in a stream. The energy current flows in a closed-loop circuit that runs perpendicular to the magnetic field. When the resistance knob turns to either increase or decrease resistance, the magnets move closer or farther away from the flywheel. The closer the magnets get to the flywheel, the greater the magnetic field, therefore higher resistance is felt on the bike.

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.

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 is also extremely quiet. 

Flywheel: Front or Rear?

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.

Indoor Cycling 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. 

Magnetic Resistance Exercise Bike Common Problems & Issues

Squeaking Noise

If your indoor cycling bike is making a squeaking noise while riding, you will need to try to pinpoint where the sound is coming from before you can fix it. Squeaking noises can come from many different problems, including issues with the belt drive or even preventable rust build-up. However, it is very common that a squeaking noise can be fixed by cleaning the bike component that has the issue before adding lubrication. Often the pedals or crank arms need a little lubrication. We recommend using a silicone lubricant, compared to more abrasive options such as WD-40.

Magnet Issues

Two issues that can occur with magnetic resistance bikes are that the magnets need to be replaced or repositioned. This is because magnets play a pivotal role in magnetic resistance. They are responsible for increasing or decreasing the workload based on moving closer or farther away from the metal flywheel. 

To assess the magnets, you will need to access the flywheel.

• Step 1:  Remove the pedals
• Step 2: Remove the flywheel shield
• Step 3: Begin your assessment of the magnets

A simple way to determine if a magnet needs to be replaced is to test it. Place one of your metal tools close to the magnet. What do you feel? If you can feel the magnetic field, you know that the magnet is functioning fine. However, the magnet probably needs to be replaced if you do not feel anything.

Magnets can also move from their original positioning, which affects their ability to adjust the resistance appropriately. You can tighten them back into position along with any other nuts and bolts while you have the flywheel shield off. 

Belt Slipping

Over time the belt will need replacing as it will eventually stretch out and begin to slip. Replacing a belt can be tricky, so it is essential always to reference your bike’s manual and follow the proper steps as each cycle is a little different. However, if you attempt to change the belt on your own, here are a few general tips.

You will need to remove the pedal crank before accessing the belt guard to access the belt. After the belt guard has been removed, the belt tension bolt will need to be removed so that the strap can be detached. The flywheel will also need to be removed to slip the belt off of the bike. After removing the old belt, replace it with the new belt and follow the steps in reverse.

However, if you decide that you would like help from the experts, you can always call a technician to help make the change.

Clicking Noise

A clicking noise or feeling often is caused by loose screws or bolts located on the pedals or crank arms. The noise or clicking feeling should go away after everything is tightened.

Magnetic vs. Air Resistance for Indoor Cycles

As discussed above, unlike magnetic resistance bikes, air resistance cycles include using a fan to create resistance. As the rider increases the speed, the resistance level also increases. The fan blades encounter more air pressure at higher speeds as they attempt to turn faster.

Types of Pedals for a Spin Bike or Indoor Cycle

Various pedals are compatible with indoor cycling bikes, including toe cages, LOOK Delta, and SPD pedals.

Clipless pedals such as the LOOK Delta and SPD will provide better form and a more productive workout allowing for a full pedal stroke and actively engaging the hamstrings in the upstroke while pedaling.
