Need manual for schwinn Airdyne Upright Cardio Exercise Bike, Older, i have a picture if needed

The wheel circumference of a 1988 Schwinn AirDyne exercise bike may vary depending on the specific model and tire size. To determine the wheel circumference for your bike computer, you'll need to measure it directly. Here's how you can do it:

1. Measure the Tire Diameter: Lift the front wheel of the bike off the ground so it's freely spinning. Use a tape measure to measure the diameter of the tire from one side to the other. Make sure you measure the actual tire, not the rim.
2. Calculate the Circumference: Once you have the diameter in millimeters, you can calculate the circumference using the formula: Circumference (mm) = ? (pi) x Diameter (mm).
   • You can approximate ? as 3.14 for simplicity.
3. Convert to Centimeters or Meters: To make it more compatible with most bike computers, you might want to convert the circumference from millimeters to centimeters or meters.

You are not going to find that, even from a Schwinn dealer. If it is only a cover (provides no other function) just use some tape.

Schwinn Fitness has many of their manuals here: http://www.schwinnfitness.com/schwinn_fitness_us/customerservice/manualsen.jsp . The direct link to the owner's manual for all Airdyne exercise bikes is available here: http://download.nautilus.com/supportdocs/OM/Schwinn/SCH_Airdyne_Evolution_OM_web.pdf . If you need the assembly directions, see the Airdyne AD4 guide: http://download.nautilus.com/supportdocs/AM/Schwinn/SCH.Airdyne.AD4.AM.EN.pdf . The AD3 and AD4 are very similar.

I hope this helps.

The age of the machine is not as big of a replacement parts hinder as is Schwinn going through so many buy outs since 1988.

One of the best exercise repair parts on online is FitnessRepairParts.com. They have consoles which are similar to your generation of machine for 170.00 - 240.00

Otherwise schwinn was most recently owned by Nautilus/Bowflex/LAMAR fitness and they may be able to help through their website.

Sorry, I don't have a great source of imformation to help with. I repair Schwinn exercise and it has become very hard to find parts recently as the new generation of AEROdynes are very different. Although, up until maybe 1-2 years ago, nothing had changed for 30 years.

Alternatively, search craigslist and ebay. You may have to buy an entire unit to get the part you desire. Often they have a drive mechanism worn out which devalues them to the seller, but has minimal to do with your search.

Good Luck.

God bless you

it may need to be calibrated. Call schwinn or Treadmill Doctor at 800-750-4766 to walk you thru the calibration.

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. Thats it. 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.
