To get these simulations, you need to learn how to adjust the resistance on an exercise bike. It provides various levels of resistance that can easily be adjusted with the push of a button. Same situation here. I wanted to purchase an exercise bike, but the bike information pamphlets say they use powerful magnetic resistance. M … Used on more expensive uprights and recumbents, it is favored by users because it is extremely quiet, in fact, nearly silent. 4-way adjustable seat suitable for people of different height. really ugly, but it should work. Best Uprights & RecumbentsBest Indoor Cycling BikesBest Minis/Under Desk. I mean, leave it unmuted if you like generic dub-step techno.The last one has good narration, plus amazingly, a chunk of solid copper the size of an apple pie, and a NdFeB magnet as big as bar of soap. The air fan bikes don’t offer adjustable resistance, but have the benefit of cooling air blowing back on you as you pedal harder. Levels of Resistance: The resistance on an exercise bike has a direct effect on the intensity levels that the equipment can simulate. Spinner bikes are an example of a bike that uses a brake pad against a weighted flywheel to increase resistance. Many feature simple knob controls for quick and easy adjustment at any point in your workout. The open flywheel or air fan bike, however, does not offer adjustable resistance at slow speeds like the other two types of exercise bikes can. Install a new console for your exercise bike. Magnets create incredibly strong forces, meaning the resistance you’ll feel with a magnetic resistance bike is strong, although it can always be adjusted if you’re looking for an easier ride. The magnetic resistance mechanism is at the heart of the stationary bike models. High-resistance cycling benefits range from fat loss to improved cardiovascular health. The pictures can give you an idea of the sort of typical geometry these eddy current brakes have. SPORTEC SS-20770 Exercise Bike Disassembly. I really don't want to completely disassemble the"flywheel" assembly. 12 - Months Warranty. The one major downside of magnetic resistance exercise bikes is that they are quite expensive.

Spinner bikes are in a class by themselves and are ideal for anyone wanting intense cycling workouts. The ordinary magnetic exercise bike has only 8-level to adjust the resistance, and the 10-level resistance adjustment gives the fitness enthusiast more choices. In fact the first 3 minutes is just blah-blah-blah-blah, and also so is everything after about 3min+30sec. ... Indoor Exercise Bike Belt Driven Magnetic Resistance Stationary Cycling Bike New. Simply put, it’s a weighted metal disk which is usually located at the front of the bike, instead of the wheel. This bike is recommended for users between 5.1” and 6.3”. At times, these knobs or buttons can malfunction that decreases the reliability of the changes in resistance. Anyway, the reason I was looking for YouTube videos on the topic of eddy currents and Lenz's Law, is because I believe these videos might help give you sort of a feel for how this magnetic damping, magnetic braking, works in practice. 5 years ago. Wait a few seconds while continuing to pedal. And, Yes, I think my bike is a lot like the picture in your link. https://en.wikipedia.org/wiki/File:Magnetic_resist... https://en.wikipedia.org/wiki/Stationary_bicycle. The second video is very good collection of eddy current demos, but there is no voice narration. £174.99. Adjusting magnetic resistance exercise bikes is commonly performed by moving a knob or pressing a button. In magnetic resistance, the bike gives you different simulations depending on the number of electric currents passing through the wheels. The resistance is changed by moving magnets causing eddy currents to create a braking effect to oppose the rotational direction of the flywheel. Thanks for any help you guys can give! 6% coupon applied at checkout Save 6% with coupon (some sizes/colors) I'm very disappointed and don't know what to do. Hi, and thanks for reading my question. Resistance is an important factor in choosing an exercise bike, more so than the actual size of the flywheel. Used on more expensive uprights and recumbents, it is favored by users because it is extremely quiet, in fact, nearly silent. Traditional breaks, as found in outdoor bicycles, are noisy and uncomfortable – something that is quickly noticeable in a home environment. This copper rim around the edge of the flywheel can be seen clearly in this video.The flywheel in the picture from the Wikipedia article ?might? It's been 2 days sinceI bought mine. Magnetic resistance is quiet but more expensive to manufacture, so it’s often found on upgraded bikes. Interestingly the outer rim of the flywheel is covered with a layer of copper. Generally, a magnetic resistance exercise bike uses magnetic power, which is controlled by electric flow and a flywheel to create resistance. Also there is some other mechanism which moves the crescent moon shaped magnet holder, closer to the flywheel when more mechanical resistance is desired, and farther away from the flywheel when less mechanical resistance is desired.Moreover I am guessing outer rim of the flywheel itself, the part that moves fastest, is covered with a layer of good electrical conductor, like copper or aluminum.That guess is based in part on a YouTube video I found recently of someone showing us the insides of a piece of exercise equipment, with a mechanism that looks very similar to the picture in the Wikipedia article on "Stationary bicycle". At the highest resistance level, it becomes difficult to pedal simulating an uphill climb on a road bike. The different kinds of resistance are direct-contact, magnetic and fan-based resistance. At the top of the flywheel, you’ll find not one, but two magnets which are there to apply resistance … The ECB or electromagnetic resistance system feels smoother when pedaling, quickly responds to resistance changes since it is done electronically on the console, and has fewer parts to wear out. Decrease the resistance level by turning the knob counterclockwise. Magnetic resistance can be adjusted either by twisting a micro-tension knob or electronically through set levels on a digital monitor. On a magnetic belt drive exercise bike, you’ll find that the flywheel is located at the front of the bike. Watch the following video to get a complete understanding of the magnetic resistance … Magnetic flywheels are the best overall; they last longer and require less maintenance than mechanical types. The good news is that in both the exercise bike magnetic vs. flywheel resistance, this can be achieved quite easily. Basically, when you pedal, the momentum is store… It is made from steel, which means it works very well with magnets. Fast & Free shipping on many items! I do not yet have a good picture in my mind of the mechanism specific to your exercise bike. Exercise Bike Safety and Comfort 99. As your legs strengthen, gradually increase workouts and gain stamina. also have a copper rim, but it is hard to see it clearly because of the angle at which that picture was taken. distances of just a few millimeters, or less.For example, looking at the picture from the mechanism from the Wiki article I linked to above, it looks like that bike has magnets made to neatly fit inside a ring-shaped channel at the rim of the flywheel.What I'm saying is, depending on the geometry of the mechanism for your bike, it may be challenging to find magnets that will be a good "fit" to the surfaces on your flywheel where you want to make eddy currents happen.I mean, you want to get the magnets very close to, but not touching, the moving flywheel, so they don't get ground into metal dust from rubbing against it.I am guessing the size and strength of the magnets needed (since you ask about this) will be comparable to the magnets it came with. Home gym equipment makes working out convenient. For example, if you're going to add your own magnet, it has to be firmly held in place somehow, because the flywheel will try to drag it with it, and you can kind of "see" how that works from watching some of these videos.Also I am wondering if your bike is truly set at its highest resistance setting. In both the direct tension and ECB resistance-style of exercise bikes, the level of resistance is selected by the rider who adjusts the amount of pressure applied to the brake. I had a defibrillator put in in April, 2008. 5kg Two-Way Flywheel with 8 Levels of Magnetic Resistance. How to disassemble exercise bike. This is because the quality and longevity of the materials are higher. Some exercise bikes have labeled resistance controls. The bike will switch to the new setting. This type of bike can last for a very long time because fewer moving parts mean that the bike is more durable, and there would be fewer issues pertaining to these smaller parts. Hi,Thanks for your answer. Although, it might actually be a square-law thing, meaning twice the magnets gives you four times the resistance.Actually, that is sort of hinted at, in the equation, on this page,https://en.wikipedia.org/wiki/Eddy_current#Power_d...under the heading "power dissipation of eddy currents", looking at this equation, P is proportional to B-squared. We are willing to put about $50 into a magnet. We have just bought an exercise bike, it uses the pedalling to power the magnetic resistance of the bike. Exercise bikes are great for strengthening the muscles and ligaments in the legs responsible for knee issues. By the way, typically the magnetic field surrounding a permanent magnet does not penetrate very far into the space surrounding the magnet. Here is the problem: at the highest setting, the resistance is still not very much. It supports weights up to 280 lbs and boasts a near silent workout. The weight of the flywheel is to provide smoother pedaling; i.e., larger flywheels pedal more smoothly and give you more momentum than smaller ones. 21 years experience Cardiology. So there is this crescent moon shaped piece, that holds the permanent magnets. That is to say, I am wondering if perhaps you arrived at this conclusion simply by looking at the bike from the perspective of its "dashboard"; i.e you turned a knob all the way clockwise, or you pushed some buttons and watched some little lights, or bars, on the display change, "boop-boop-boop -- okay, guess that's got it turned up all the way..."I mean, I think a true measure of whether or not the resistance is turned up all the way, is to look at the gap between that crescent moon shaped thing and the flywheel. How to replace the resistance motor in an exercise bike. I was hoping that I could just cut a hole in the top cover and use a mounted magnet with fine screw adjustments to adjust the distance between magnet and flywheel for optimum results. If you understand how the intensity/resistance works in these stationary bikes, you will have a better idea of which type of bike is better suited for use in your home.

As a result, the magnetic resistance bike … Happybuy Magnetic Exercise Bike, 901 Adjustable Seat Folding Exercise Bike, Rotary Adjustable Magnetic Resistance Under Desk Exercise Bike with Electronic Display, Sports Bracelet for Cardio Training. Magnetic resistance is a common choice and has the benefit of being whisper quiet, so you can watch television or listen to music without the sound of your bike drowning it out. The advantage is that it requires more energy to get the larger open flywheel in motion, while a smaller flywheel on a standard stationary bike requires minimal momentum to start out. 6 - Levels of Seat Adjustments, Monitor Displays Speed, Distance, Time, Calories and Pulse. The sound is just some generic techno music. The control knob is between the handlebars on the bike’s stem. Here’s a detailed look at what each contributing factor does: The Magnet. Magnetic Brake. Hi, and thanks for reading my question. The first type uses mechanical resistance provided by the friction of moving parts such as a roller or brake pads that apply direct pressure to the flywheel, which is attached to the pedals. A modern design of exercise bike resistance technology is the electromagnetic brake. was - £349.99 | 50% OFF. Modifying your ride's resistance or duration can help you harness them. A modern design of exercise bike resistance technology is the electromagnetic brake.

Elite Polaris Magnetic Spin Bike. The Schwinn AirDyne, a popular bike model that has been in use for decades, is a good example of this design. And I don't think they would swapIt for another bike... as they told me that was the last one of this model in their stock. How Does a Magnetic Resistance Exercise Bike Work? Another type of exercise bike resistance comes from pedaling against the airflow of a fan blade located on the front of the bike. The biggest benefit electromagnetic brakes is that you can ratchet up the resistance quickly by pressing a button on the electronics console. Magnetic resistance bikes are very common nowadays because of the fact that they don’t have a lot of moving parts. We think that maybe we can increase the resistance by putting a strong permanent magnet near the flywheel, (we would cut a hole in the plastic cover to put the magnet near the flywheel). The first does not need sound because the narration is almost worthless. A bike can have either manually adjustable magnetic resistance or digitally adjustable magnetic resistance. A 49-year-old male asked: i walk and ride my mountain bike for exercise, recently got back into resistance training, how important is that to an overall exercise program? The forums are retiring in 2021 and are now closed for new topics and comments. Last Updated: February 3, 2020. It can be adjusted without much hassle. To prevent injury stretch muscles, joints and start with a short workouts. But problems can arise. Manual magnetic brake exercise bikes use a tension knob located between the handlebars to work the brake the same way as ECB. Can somebody please help me in this. The electric console is responsible to control the speed and resistance intensity. Sort of a naive guess, would be to say that twice as many magnets, or magnets twice as strong as the existing ones, would give you twice the resistance. Folding Exercise Bike Upright Cycling Magnetic w/Resistance Band. Friction resistance is less expensive and often found on lower-priced bikes. How Does a Magnetic Resistance Exercise Bike Work. Answer JLL RE100 Recumbent Home Exercise Bike. exercise bike magnetic resistance. If you have to manually adjust the magnets with a tension knob, the resistance will only change as fast as you can turn the knob, and the use of a manual system may cause you to break your exercising cadence. These usually consist of 8 levels of resistance with a simple internal cable adjusting the magnets to and from the flywheel for resistance change. How to make the time spent exercising fun! $250.00. The resistance component is necessary to make pedaling more difficult or easier and to give you a better and more varied workout.

Exercise Bike Benefits Less impact on joints: Cycling on an exercise bike reduces the impact on your joints, compared to cardio exercises such as … ... Usually, on cheaper upright models, turn the dial to increase and decrease the resistance with no automatic change. Dr. Elden Rand answered. A magnetic field is used to create the resistance the bikes needs. Magnetic resistance exercise bikes can cost more than other types of bikes. Spinner bikes are an example of a bike that uses a brake pad against a weighted flywheel to increase resistance. This is because magnetic resistance can be very costly to produce. by changing the ratio of the sizes of the pulleys, or sprockets, driving it, I would expect that to cause the eddy currents to consume more power, and give you more resistance for the same pedalling speed. Exercise bikes are very popular these days but, to get the best experience, you need to find a magnetic option. ), and what shape would work best (disk, rod, etc...?). When you increase the pedal resistance, the magnets move closer to the flywheel, creating tension. This exercise bike comes with 8 preset magnetic resistance controls. My powers of clairvoyance are not yet developed enough to see your exercise bike sitting in a room in your house, and moreover to see underneath its opaque plastic cover, for to see what is happening with its flywheel and its magnets.Perhaps it looks just like the one in this picture,https://en.wikipedia.org/wiki/File:Magnetic_resist...from the Wikipedia article on "stationary bicycle"https://en.wikipedia.org/wiki/Stationary_bicycleOr maybe it looks like something else I have not seen before?https://www.google.com/search?hl=en&tbm=isch&q=mag...If there is a way to make the flywheel turn faster, e.g. Now, with a magnetic resistance bike the magnetic force can be very powerful meaning less weight is needed of the actual flywheel to cause resistance (to slow down the flywheel) On a friction based bike, the felt pad(s) will slow down the flywheel by using the friction as resistance however the energy you exert can often be greater than the friction needed to slow down the flywheel. It is generated through an electric circuit, pedaling action, flywheel, and a wheel gearbox. When you decrease the pedal resistance, the magnets move farther from the flywheel, making it easier to pedal. It uses an open fan instead of a flywheel and creates stronger resistance as pedaling speed increases. The Marcy NS-652 foldable exercise bike is a heavy-duty 14 gauge steel frame construction measuring 32L x 18W x 42H, weighing 37 pounds with a maximum weight capacity of 250 pounds. If these are so close they're almost touching each other, then that means the resistance is turned up all the way.Anyway, I think I promised you some video links.

Hey guys i wanted to know what grade of magnet is usually used for magnetic resistance exercise bikes. Also I forgot to mention, a permanent magnet electric motor can be used as a eddy current brake; i.e the shaft gets harder to turn if you put a short-circuit, small electrical resistance, across its inputs, compared to those inputs being open-circuit. Can someone explain how to figure out how strong a magnet would need to be? If you find your magnetic resistance exercise bike not working, try these steps. When you dial down the resistance, the magnets are moved away from the flywheel and the bike is easier to pedal. There are two main types of resistance on an exercise bike: Friction Resistance and Magnetic Resistance. Most exercise bike manufacturers will commonly offer warranties for parts and construction that allows you to replace the parts of the magnetic resistance system that aren’t working properly. At the heart of most home exercise bikes is the flywheel. Here is the problem: at the highest setting, the resistance is still not very much. Thanks in advance. So you can set your workout intensity levels according to your desired routine. The flywheel, in its essence, is a mechanical device used to store rotational energy.
