Magnetic Vs Friction Resistance for Spin Bike [ Which Is Best? ]

Magnetic Vs Friction Resistance for Spin Bike
Spread the love

Resistance plays a massive part when spinning. It is to resemble outdoor cycling in the sense that when cycling uphill, the harder it is therefore the more effort needs applied or even when cycling downhill, it’s much easier so less effort needed.

 

Resistance on spin bikes come in 2 forms – Magnetic and Friction based resistance.

 

To understand each one, we need to look at the mechanics behind each type before deciding which is the best one for your needs.

As the name suggests, magnets are at work here.

 

So, on a standard spin bike the flywheel is situated at the front of it, just ahead of you between your legs. The flywheel itself is made of steel, not only is this great for the weight needed to offer a smooth cycle but by nature it is a great magnetic conductor. There are two magnets located at both sides at the top of the flywheel that will help generate resistance.

Magnetic Resistance on spin bike

This works in 2 ways, either by a manual turn crank or an electronic console. So by the turn of a crank or push of a button, the magnets will push closer together to the flywheel helping to slow the flywheel down and create resistance.

 

Turn the crank the opposite direction or push the button to turn down the resistance and the magnets will be pulled away from the flywheel – removing the resistance.

 

Ever hear the phrase opposites attract?

 

Well, not to start a physics 101 class here but bear with me. So every magnet has a north and south pole and it’s when these two opposites attract, they pull together with incredible force.

 

Put a conductor between these (a flywheel) and resistance will be created.

 

This is how the mechanics work behind a magnetic resistance spin bike.

 

One bike that offers incredible magnetic resistance is the Keiser M3i.

 

Not only does it come with some of the best features and one of the most accurate readings in indoor cycling but it’s flywheel is also located at the back.

 

This helps to reduce wear and tear – keeping it away from the sweat zone and keeping maintenance costs at an absolute minimum.

Friction Resistance

This is a form of resistance applied to the flywheel with strong cotton felt pads.

 

These are either located at the top of the flywheel which are compressed down on top of the flywheel creating friction, which will give resistance.

 

More commonly used is when the cotton felt pads are located at either side of the flywheel though.

 

Once the resistance crank has been turned up, these pull a wire and compress the cotton felt pads into the flywheel generating resistance.

 

The XS Sports bike is an incredible bike that uses friction based resistance.

Difference In Noise

With friction resistance, there needs to be something rubbing against one another to create that friction, in this case cotton felt pads against the flywheel.

 

This creates a very soft ‘whooshing’ noise, almost like a silent whistle but it is by no means noisy.

 

On a spin bike with magnetic resistance, there is nothing touching each other. They don’t need to due to the force of the magnets. It would be very difficult trying to pinpoint any noise coming from the magnets, that’s how silent they actually are.

Is There Much Maintenance?

With friction resistance, the cotton felt pads will be worn down over a certain time period with consistent use. If you were to look at the front of your spin bike you will see fibers over the front stand that have worn away.

 

If you feel that the resistance isn’t working as effective as it should be, it may be time to replace the cotton felt pads.

 

Magnetic resistance however requires very little maintenance as once again, there is nothing necessarily touching each other. The magnets are completely independent from the flywheel.

 

Every now and again, batteries may need replacing from the display unit, a wire or few bolts may need tightened but apart from that maintenance is very little.

 

In the rare circumstance that it does need repairing, follow this guide to fixing the problem.

Difference in Costs

Magnetic resistance spin bikes are more an expensive bike compared to a friction resistance bike simply as they cost more to produce and have more ‘perceived benefits’ such as being quieter and have very low maintenance.

 

Friction resistance bikes are less costly to manufacture so tend to be a lot cheaper. You could get a friction resistance bike a couple of hundred pounds cheaper than a magnetic resistance spin bike.

Which Has a Better Resistance

Resistance can differ only but very slightly from these two different types of spin bikes however they are absolutely both excellent in adding and holding the resistance throughout any workout.

 

Friction resistance tends to be the better candidate at holding a higher resistance – this is simply due to actual connection of the cotton felt pads against the flywheel.

 

The magnetic resistance is by no means the worst, it still holds a powerful and high resistance. It’s just as there is no actual connection against the flywheel, even at its highest resistance you may still be able to slightly push through.

 

On the friction resistance spin bike, with the resistance cranked up to the max – pushing the pedals to move the flywheel is virtually impossible.

 

With either type of spin bike, you’re never going to be training so hard that you need the resistance cranked to its highest level. You’ll have it turned up and down yes, but never at the point where it’s almost impossible to move.

Emergency Stop

Every good spin bike should come with an emergency stop. It’s just a necessity that if you feel you’re pedalling uncontrollably or start to feel niggles or pains – you can hit the emergency stop and the flywheel will come to an automatic halt.

 

It’s basically the same process of what I described above. Instead of the resistance being incrementally added on over time, the entire resistance is thrown on an instant.

 

On a friction resistance bike, the cotton felt pads automatically engage with the the flywheel pushing hard against with so much pressure that the flywheel stops.

 

The magnets on the magnetic resistance bike come into very close proximity very sharply once the emergency stop has been pushed and the flywheel loses all its momentum and stops in a split second.

 

I have to say that both types of resistance spin bikes outperform themselves here so you’ll be sure to stay safe when cycling.

Conclusion

So just to recap on a few of key points:

  • If you’re after a ‘quieter’ spin bike, the magnetic resistance bike is what you want
  • There is little maintenance involved with the magnetic resistance bike and over time you may need replacement pads for the friction resistance bike due to wear and tear.
  • The friction resistance spin bike is going to be a lot more affordable compared to the magnetic resistance bike so if money is the issue you may want consider the friction resistance bike.

Whatever bike you choose, both are going to give you exactly what it says on the tin – an effective fat shredding workout.

  1. Hello,

    Thanks for the information between magnetic and friction. Wondering if you can give some advice between sole SB700 and SB900. I prefer the 700 due to slimmer profile but the sb900 magnetic is tempting although it is over my budget.

    Thank You

    1. Hi Emmanuel,

      I’m glad you liked it!

      Yeah, the Sole SB700 & SB900 are two great bikes!

      Very similar in both design and functionality

      As you mentioned the SB700 has a slimmer design to it whilst the SB900 has a more bulkier frame to it.

      This doesn’t necessarily mean it can handle greater weight – both can actually hold up to 135ks or 297lbs.

      In terms of cycling – all features are more or less identical

      Where the differences lay between the two of them is that the SB900 now includes SPD Pedals and an eddy current magnetic brake resistance.

      This allows the bike to be that bit more quieter along with a greater resistance placed upon the flywheel.

      Two awesome bikes though!

      I hope this helps

  2. Hi Ronan,

    I have been researching before buying a spin bike and started to learn about the magnetic vs friction resistance and belt vs chain. Glad I found your place! I am now between two options and hard to decide between Joroto x2 or dmasun, both on amazon:
    https://www.amazon.com/JOROTO-Magnetic-Resistance-Exercise-Stationary/dp/B07Q2697YN/ref=sr_1_1?dchild=1&keywords=joroto+x2&qid=1590202756&sr=8-1

    https://www.amazon.com/gp/product/B07X6GHLLT/ref=ask_ql_qh_dp_hza

    what would you suggest? is it really worthy to go with the Joroto for the magnetic resistance? I have never tried a magnetic resistance bike and considering these two are both with belt, not sure if the noise level for the most affordable one(dmasun).

    Thank you!!

    1. Hi Anny,

      Looks like two great spin bikes there!

      As you’ve stated there that both of these bikes have a belt drive rather than chain -which is great at keeping sound to a minimum.

      Your right, the Joroto has magnetic resistance whereas the DMASUN has a friction based resistance.

      These are basically felt pads located just above the flywheel that are forced onto it when resistance is increased.

      In terms of keeping noise to a minimum – I would recommend the Joroto with the magnetic resistance here!

      It’ll be very quiet to cycle and actually has a decent flywheel weight also at 35lbs (15kgs).

      You’ll be able to get a smooth ride out of this!
