So I recently scored an oldschool airdyne for $20. When I showed up the seller said the emails were overwhelming. The guy even helped me load it into my vehicle - it's a beast. Anyway, what he didn't mention in the ad, nor did I care for the price, was that the ergometer didn't work. This ergometer is like the one in this photo (half analog, half digital): The ergometer is non-responsive. When I pedal the analog dial doesn't move.
So a couple questions before I open it: 1) Anyone know if the analog dial needs a battery to operate? 2) Is there a recommended parts website for these bikes/ergs?
3) When researching between the Airdyne and the Assault I had read that there were differences between how the erg calculated calories. I'm not too interested in buying the $300 replacement digital erg, but I would be interested in building my own.
So is there any public info on calculating the calories? Thanks PS - that was $20 CDN. So yeah, $16USD. Hey Grape, if it were me I would connect a new bicycle computer to it.
I did this with an old Tunturi Ergometer and it was great. I recommend a Filzer from MEC. There's a model for $27 that has two speed pickups, one for crank RPM (this is what you should be most interested in). It won't give you same calculated watts, calories, or perceived effort level as the Airdyne computers, but the older bikes don't likely do that anyhow. Let me know if you need help with something like that. I believe we're in the same town.

Thanks PS - that was $20 CDN. So yeah, $16USD. I paid $20 US for mine. You got me beat. 1) The analog speedometer is just an ordinary mechanical bicycle speedometer with a special faceplate.
It has a square cable that connects the wheel to the speedometer. No electrical power required. 2) Check out these sites. They sell Schwinn Air-Dyne parts: Sports Smith Air Dyne parts National Gym Supply Air-Dyne parts Krislynn Cycling and Fitness: Parts and service, with videos Airdyne Main Frame Parts Airdyne Pedal Drive Parts Also check out ebay. There are many sellers of parts there. As for the digital timer, I easily repaired mine. I disassembled the digital timer and cleaned the circuit traces under the buttons.
Now the buttons work every time. For power, I installed a pushbutton switch (not a momentary contact) in the battery hole (love my glue gun) and added a single cell battery holder to the bottom of the ergometer.
Radio Shack parts for about $5. My timer does not shut off after a certain time, so I used a switch. But considering that it is a simple LCD timer, a single battery will probably keep the timer powered on for a year without a switch. So I recently scored an oldschool airdyne for $20. When I showed up the seller said the emails were overwhelming.

I have three AirDynes. I was getting one ready to sell one Craig's List and making sure I had all good parts on the two I am keeping. I swapped the good console to the one I am keeping and when I tested it, the speedometer was not working. The speedometer was working on both machines before the swap. After some fiddling I determined it was the speedo sending unit.
The plastic housing cracked and the worm drive was only intermittantly engaging. The first pic shows the speedometer sending unit on the fan axle with the speedo cable connected.
The picture below shows the speedometer sending unit. The 25+ year old plastic cracked right clear through.
The other sending unit had a similar crack. On the sender that worked there was a lot of resistance when spinning the hub compared to the sender that worked intermittantly. I was not able to find a source for these sending units. When the one that I have finally stops working I may try clamping the sender housing to see if closing the crack will make it work better.
The top part is a digital timer. The Up-Down arrow buttons adjust the time in minute increments. Third button is start and stop the timer. If the time is 0, time counts up. If the time is set to anything else the time counts down.
The rightmost button is a reset. It returns the display to 0:00. The instructions I've seen say the timer shuts off after a minute or two. Mine does not, but a battery should last a year or so with the LCD display on all the time. Regardless, I hot glued a pushbutton switch in the battery hole and wired a AA battery holder into the circuit. I hot glued the battery holder to the back of the console. I cleaned the circuit board so that the buttons make good contact because my buttons were intermittent.
The analog speedometer shows:. Load from.5 to 10 (some only go to 7). 1 load level = 50 watts, so 6 = 300 watts. Pedal RPM from 28 to 75 RPM in odd increments. Odometer. Trip odometer with rotary knob on back to reset Here is a sharper view of another speedometer (image grabbed from Google images): But if you want to throw all that away, a bike computer should work fine.
You just need to remember that the load does not increase linearly with RPM. Picked up my dad's old Airdyne last week. The speedometer sending unit is fine, but the cable is broken. Cable and sheath broke about an inch from the sending unit.
Interestingly - if you pull the cable out of the sheath, it appears to be a tightly spiraled thin wire. The nearest I can describe would be like a damascus gun barrel.
The area where it broke looks to be bunched up and I don't think it's grease. Now that I think about it, I will have to pull the sending unit off to make sure it is rotating smoothly because it looks like the cable was twisted until it broke. Anyway - anyone know where to get the replacement cable? The krislynn site listed above offers a replacement cable but it is an electronic cable for the modern computers. Also - RestoringTally any chance you can post some pics of the wiring you did for the push switch? Sounds like a great idea, heck the AA battery sounds like a better option than the button battery. Wonder if I can do that with my Concept II's PM1 as well.
Here's a simpler and possibly more versatile solution: All that box does is incorporate a very old school timer and a direct-drive speedometer that actually has no relationship to real speed because there is no real wheel and no real gearing. So just get a Wahoo bluetooth cadence sensor and zip tie it to the crank. It transmits directly to a smartphone, iPad, computer, whatever, and gives you cadence, which is really all you're getting from the original speedo anyway. You can also get a bluetooth heart rate strap and have both cadence and heart rate transmitted to your smart phone to any of a variety of apps there. You can record your workout, monitor performance real-time, and get the same results you'd have with a heart rate monitor plus the Airdyne direct-drive speedo. Cleveland, Check out W.
They have dynamometer cables that do exactly what this does. For a few bucks, find if it's the cable or the dial that's broken. Or the pickup worm gear. But the real answer to your question may be that Airdynes are old and very dated and for the most part pretty worn out. Except for a few weightlifters, most people who want something to do leg-spinning workouts go buy a used Monark ergo, a Lemond or CyclOps trainer, or something like the Wahoo Kickr. The Monark is much more solid than the Airdyne but you may still find yourself doing some repairs if it isn't in decent shape. Lots of ways in the end to get this kind of workout.
Of all of them, I'd just put the Airdyne close to the bottom of the list. Better choices abound.

Today, we are going to take a look at the Schwinn Airdyne AD6 and see what it has to offer compared to the AD2, AD4, AD Pro, Evo Comp and the Assault Bike. Let’s get started! The Airdyne AD6 is a quality fan bike that will give you a hardcore workout if that is what you desire. Many times the AD6 is used for high endurance exercises by gurus.
However, beginners should also be happy with the AD6. So, whether you are looking for a lower resistance calorie burn or an extreme cardio or HIIT exercise, you will have it all.
Assembly The AD6 comes partially assembled, most users can put the rest together in an hour or less. The instruction manual is very clear and includes the proper tools to assemble your machine. Not to mention, everything is labeled accordingly, which is a huge plus. The worst part of the assembly is going to be the weight of the machine inside the box before you unpack it. You might need to ask a friend or relative for help, to prevent injury to yourself or your new purchase. Once you can get a hold of the stabilizer bars, you should be good to go. The seat might also need a little tweaking with an adjustable wrench.
The tool that the manufacturer does not always get the job done. You will also need to add a few parts yourself. The console, pedals, seat, handlebars, water bottle holder and adjustment pole will need to be assembled onto the bike.
Construction Please note that the AD6 has a muscular build. Constructed of mostly steel, you will not find the AD6 shaking and wobbling around while it is in use. Everything seems to be welded and situated together quite well. You can not beat the warranty either. The frame comes in at a colossal 15-years, along with a 3-year parts warranty, two year electrical, and six months of labor.
Most bikes of it’s kind will not come with such an incredible guarantee. Who knows, you might not have to use the warranty options with this extremely well-built model. The AD6 is known to take a licking and keep on ticking.
Adjustments There is only one feature that might need some extra tweaking, and I have already mentioned it. The seat’s height will likely need a proper adjusting. You will want to be sure that your legs are in the best possible position, for comfort purposes and to prevent injury. Sadly, you can not adjust the seat horizontally, so you might find yourself too close or too far away depending on your height. If you are under 5’3″, you might have trouble getting a hold of the handlebars because they can not be adjusted. Something that I find satisfying is that the handlebars move back and forth with the pedals, making things a tad easier.
Adjustments for vertical seating is also quick and easy. Resistance Being a fan bike, you control your resistance levels. Controlling a resistance level of your own makes the AD6 perfect for CrossFitters and even beginners. The fan pushes air which creates a heavier resistance as you pedal.
ABS plastics were used to craft the fan itself. ABS plastics are known to be incredibly durable and should last for years to come. The fan’s positioning is proportioned forward. Some users do not like to be hammered by a breeze while they are pedaling, making the forward positioning a plus for many users. If a person wanted to, they could pedal backward to create a breeze. However, your pedals could also come undone if you choose to pedal backward.
Belt drive One thing that I like about the AD6 is the dual-stage super-torque drive belts. These provide a smooth and peaceful ride as well as a low maintenance level. This kind of drive belt will last for years, and should not need replacing for quite some time. When the day comes for replacing, I have to inform you that you will likely need to hire a professional. Specific tools may need to be used to replace a belt drive. The dual-stage belt drive is also heavily protected by plastic. The plastic piece will prevent sweat and dirt from corroding your machine.
You should also be happy to know that it protects against loose clothing, limbs, and fingers too! Comfortability Pedals I’ve always liked pedals with straps, and that is what you will get with the AD6. The straps will hold your feet into place and should prevent slipping. You will find that you can wear regular shoes or special training shoes. This model also comes with a fixed gear, so your pedals, fan wheel, and handles will move in the same rotation. You can specifically train your arms if you prefer.
There are foot rests at the front of your bike and out of the way of the pedals. The foot rests a slick feature. Handlebars As I just said, your handlebars will move back and forth when the bike is in motion. There is not a way to set them into place. You will likely find yourself with your hands down to your sides if it strictly legs day. People of smaller stature might have a hard time trying to lean forward to reach the handlebars when the handlebars are at their furthest forward positioning. Some might find this uncomfortable, and a real pain in the neck (or arms).
Seating Most users claim that the seat is pleasant with its considerable size, and extra padding. If you do not like the original seat, you may exchange it for a standard bike seat. To attach the seat to the pole, you will need to purchase a clamp. Weight limit The limit for this model is 300 lbs, which is pretty impressive. Water bottle holder You may be asking yourself, ‘How is a water bottle considered a comfortability feature?’. Please allow me to explain.
The holder is at the front of the bike, which means that you will not have to sit next to a table or stand. But take precaution! When you reach for your bottle or return it to its holder, you will need to keep an eye on the handlebars, or they might hit your arms.
Being mindful of this feature is a good idea. It could provide a pleasant or unpleasant experience. Console The AD6’s console is going to be very basic, which is all you need for a hardcore exercise bike.
The lettering/numbers are sizable and easy to read. You will want to make sure that you are in a well-lit room because this console does not have a backlighting feature. Other than that, it displays everything that you could want from the RPM, time, distance, watts, speed, calories, and heart rate. Although, you will need to purchase an uncoded Polar compatible strap to sync to your machine. That is of course if your heart rate is important to your exercising style.
Your top screen is going to show a new RPM RevMeter and will show you have how you are pedaling. It is one of newest features. The time display goes up to 99:59, but will reset itself if you go over. Speed and distance are in miles or kilometers. It depends on which one you would prefer. Watts will go by how much work you put into your routine.
The resistance will not be like a regular bicycle but will get the job done. Your calorie-burning statistics will consist of an estimate.
You can also put your height and weight in, but are not required to do so. You will notice that they are three buttons for starting, stopping, or pausing. You will also be allowed to adjust your timing goals, set your KMS or miles, and enter altitude.
The console also requires two and notifies you when your batteries are wearing thin and need replacing. The console also includes a five-minute timing feature, where it will power itself off when it does not detect movement. Some users will love this and may find time to use the bathroom, fill a water bottle, or take care of another quick issue. The console can be programmed to monitor the length of your exercise and will count down. If you hit the pause button, it will display your current statistics, but you might want to jot them down on a notepad. This console does not save statistics in its database or let you upload them to an application program. Accessories A reading rack and windscreen are purchasable as separate accessories for the AD6.
The reading stand is a nice feature, that will attach to the front of the bike. It will allow a tablet, book, cell phone, and many other things. Some users have reported that it was difficult to install.
The windscreen is not necessary for most users. With the fan being so far in the front of the machine, I don’t see where it will be a problem. However, if you choose to buy the windscreen, it is an easy install. Quick note The AD6 instructions are quite impressive and even give advice on the best training zones, adjustments, and ideas for different training methods. You can also find videos on Youtube! Comparisons Schwinn Airdyne AD6 vs.
Schwinn Airdyne AD2 From what I can see, the AD6 beats the AD2 by miles and miles. The AD6’s durability is far more superior. It comes with a water bottle holder along with two other accessory options, has a bigger seat with extra padding, and has a much longer warranty. The AD2 is quiet, but not as quiet as the AD6. It only accommodates a weight limit of up to 250 lbs and has a much smaller console screen. Not only is the console smaller, but it sits low to the ground, making it awkward.
The AD6 also displays your measurement all at once. Because the AD2 has a smaller screen, it does not have the same capability; it can only present one statistic at a time. The AD2 does not have the option to monitor your heart rate or watts. It does not allow you to set goals either. So, if you want to count your burned calories, time or distance, then you will not be able to do so. The biggest plus that I found about the AD2 was its size.
It is small in stature and will take up a little less room than the AD6. Schwinn Airdyne AD6 vs. Schwinn AD4 There are many similarities between these two pieces of machinery. The biggest complaints about the AD4 are the sound and comfortability of the seat.
Although, the AD4 comes with an excellent warranty at 30 years for the frame, three years on parts and electronics, and a one-year labor warranty. If you want a quiet and more comfortable bike, then I would stick with the AD6. Schwinn Airdyne AD6 vs. Schwinn Airdyne AD Pro I must admit, the AD Pro has some great features compared to the AD6. But it also lacks a few important things.
We know by now, the AD6 does not have any pre-set workout programs. The AD Pro does have nine workout programs to target your goals and desires. While the AD6 has a high-resolution LCD screen, the AD Pro has a higher contrast, allowing you to view it a little easier.
Some users say that the AD Pro’s seat is not nearly as comfortable as the AD6, and may need replacing with a standard bicycle seat. My favorite feature of the AD Pro is the fact that the handlebars can move around. You can position them vertically, or horizontally. Another kicker of the AD Pro is the warranty. You get five more years in the frame for the AD6, and an extra year for parts. Schwinn Airdyne AD6 vs. Schwinn Airdyne Evo Comp Although the Evo Comp does have two workout programs and a generous warranty of 30-years for the frame, three years on parts and electronics, and one year for labor.
It does not compare well to features of the AD6. Many have reported that the seat is significantly uncomfortable, the fan is not set very far forward which creates more wind than you may have bargained for, assembly instructions are poor, and the pedals are cheap quality.
Some say that the fan provides just the right amount of wind flow for your workout. But, it is not everyone’s cup of protein shake.
Not to mention, the Evo Comp works more like an elliptical than your average exercise bike because of its ability to work your upper and lower body at the same time. Schwinn Airdyne AD6 vs.
The Assault Bike Many exercise enthusiasts claim that these two machines can go head to head, but which one is truly the better deal for you? Let’s a take a look at the mighty AD6 vs. The all-powerful Assault.
First off, I found that these two are very similar in many aspects. The Assault Bike was designed for a brutal workout, as was the AD6.
Both are heavily sturdy and should last for many years. The Assault’s console has a sleeker look and is easier to use.
It is also simpler to assemble until you need a longer wrench. Most users reported that they had to use a crescent wrench to make the bolts stay in place. You want to be sure that they are screwed in tightly, for your safety and everyone else in the vicinity. The weight limit on the AD6 is 300 lbs, where the Assault bike can hold up to 350 pounds. Neither the AD6 or Assault have pre-set workout programs. But again, you won’t need them with either of these bikes.
One of the great things about the Assault Bike is the adjustable seat. You can take it upwards, downwards, forwards, and backward to help fit each separate rider. There have been reports of the Assault Bike’s seat being a little too uncomfortable. Some have successfully exchanged it with the Sunlike Cloud-9 Bicycle Suspension Cruiser Saddle.
One of the things that I loved the most about the AD6 was the straps on the pedals. The Assault Bike typically requires just as much exercise but does not feature foot straps. Lacking foot straps could cause some unwanted strain or injuries. The Assault has a chain drive, compared to the AD6’s duel-state super-torque belt drives. Making the Assault Bike’s chain drive a little more aggravating in comparison. Chain drives typically need routine maintenance with lubrication and adjusting of the tension.
With the AD6’s belt drive, it is much smoother, and only has a hint of noise. Plus, the belt drive does not require routine maintenance or replacing for years to come. As for sound, the Assault bike has metal blades, creating a different sound. The AD6 has plastic blades, which makes stronger results and provides better resistance. You also can’t escape the fact that metal fan blades might be an incredibly bad idea if you have small children or pets running around your home or gym.
You will not be able to buy extra accessories for the Assault bike, as it is a very simple machine. The warranty is not bad either but does not come close to the AD6’s warranty, which is ten years longer for the frame itself. Overall evaluation of the Schwinn Airdyne AD6 I feel like the Airdyne AD6 is easily the best bike out of the bunch.
It has fantastic reviews all over the internet, without much criticism. You simply can not beat a bike that is built to be quiet, durable, safe, comfortable, easy to put together, has an incredible reputation, added accessories for purchase, has a massive warranty, and where you can set your pace with hardcore CrossFit exercises or light weight beginner exercises. Remember, you set your resistance levels when you pedal the bike.
The harder you pedal, the more resistance will build up around the plastic fan blades. With the lengthy warranty, you should be all set with your purchase. Many users claim that they have not had to replace anything on their AD6 machines. The console is tough to beat.
When you have the RPM, time, distance, watts, speed, calories, and heart rate, what more could you want on a console? Three buttons make it easy to do what you need to do without much hesitation or confusion. The transport wheels make it easy to move, and it takes up little space. Nobody wants a machine that looks like a log and feels like one too.
Moving from home to home can become a real problem when you are lugging around heavy exercise equipment. The easy to reach water bottle holder is fantastic if you can avoid getting hit by the swinging handlebars. Again, be on the lookout for those bars! I feel good enough about the AD6 that I am considering a purchase myself. If you are not sure, you can always check your local YMCA, gym or park board for an AD6 or any other machine that I have listed. Most gyms will have these high-quality machines in their facilities. Sometimes it is best to try before you buy, then again, I have broken it down for you.
So, it is time to make a decision, and I hope that I have helped with that task. We all know that it can be quite the task with so many exercise machines in the world. There is always something new, bigger, and better. I feel like the Airdyne AD6 will hold it’s own for many years to come and will be in gyms and homes all across the world. I love bikes (can you tell?). I used to race them back when I was younger and had more free time. Now I just ride for pleasure and work on bikes when one of the local bike shops needs an extra hand for the day (or a bike race needs an extra wrench).
There aren’t many sites with current bike reviews out there — especially for the beginning rider. It is my goal to fill this gap with accurate reviews and helpful information to make bike buying (and riding!) more enjoyable.

The analog speedometer shows: Work Load from.5 to 10 (some only go to 7). Pedal RPM from 28 to 75 RPM Odometer Trip odometer with rotary knob on back to reset The white numbers around the dial (from 1 to 10) are Load; the red numbers around the dial (from 28 to 75) are Pedal RPM (rounds per minute). There are two odometers: the Odometer on top (four white digits plus 1 black digit) measures total miles traveled on the machine.
The odometer on the bottom (two white digits and 2 black digits) is a 'trip odometer'- you can reset this by turning the little knob on the back of the ergometer. Load: Level 1 = 50 watts, Level 2 = 100 watts, etc. It is a measure of the power you are producing at the moment; it changes based on the intensity of your workout. Load is also related to how many calories you are burning: Energy (kCal or 'calories') = Av Power (Watts) x Duration (hours) x 3.6. Exercise equipment especially cardio equipment will often display this measurement. By maintaining a certain load level, you can work at a consistent level of intensity. Posted on Jul 11, 2017.
Airdyne Chain Replacement with Master link This video will demonstrate how to replace the chain with master link on a Schwinn Airdyne. First remove the cotter pin and clevis pin from the user's right handlebar. Then lower the connecting arm and handlebar. Caution: be sure to hold the handlebar as it will come loose after removal of the above parts. Remove the connecting arm and pedal and crank arm by removing the wedge pin. To simplify this process loosen the nut and tap on it with a small hammer until the pin is loosened. Remove the nut, wedge pin, crank arm and connecting arm.
Next remove the chain guard; there are three screws attaching it as shown in the video. Remove the chain by locating the master link. Remove the lock pin and the cover, and then disconnect the chain.
Place the new chain on the sprockets as shown in the video. Install the master link, cover and lock. Re-install the chain guard and attaching screws. Re-assemble the connecting arm to the handlebar and eccentric.
Be sure the brass bushing is installed in the front inner side of the connecting arm before installing the clevis pin and cotter pin. Install the crank arm with pedal. Be sure when completing this step that the crank arm is installed in the opposite position as the users left side crank arm.
Install the nut onto the wedge pin and tighten. This completes the procedure. On May 23, 2016. How To Identify the Model of a Schwinn Airdyne Exercise Bike. We'd like to share some characteristics of the that can be used to help you identify the model of your Airdyne bike.
What size/type fan does it have? Is it a spoke fan like a bicycle wheel or short wide blade fan?. Big Fan (spoke fan like bicycle wheel) -, AD4, AD Pro/Comp. Short Fan (wide blade) - Does your Airdyne bike have two chains or a chain and a belt?. AD3, bikes have two chains.
AD Pro/Comp and AD Evolution Pro/Comp bikes have a chain and a belt. How do the crank arms attach to the Airdyne, by wedge pin or bolt?. AD3, AD4 and certain crank arms attach by wedge pin. Certain AD Pro/Comp bikes have crank arms that attach by bolt. AD Evolution Pro/Comp bikes have crank arms that attach by bolt. On Mar 11, 2015.
Follow this link and you can download the owners manual as well as the exploded parts schematics. There will be information about the different years. Other than the consoles they have remained the same for 20 + years.
If you ever need to replace the bottom bearing be sure to get the lock ring as well. It changed from left hand thread to right.
You can also upgrade the console to the newer version. A little expensive but with proper care a 20 year old Airdyne will last till the frame rusts out from under it. Apr 23, 2009.
