What is the wheel circumference of older 1988 AirDyne to use for bike computer to replace Schwinn ergometer?
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:
- 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.
- 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.
- 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.
Load indicator and odometer and
Same here. Can't find the part online. Local Schwinn dealer said they haven't made that part in at least 10 years. I put on a regular bicycle Cateye odometer. At least I have a measure, although it does feel like it agrees with the Schwinn odometer, even when I set the wheel size to just 100 cm I think it is still ~20% high.
How do you adjust the seat
Hi there Vriddick
To adjust the seat for height, there is a locking bolt on the seat post, below the seat. Loosen this and the seat should drop down the hole. Lift it up to your specified height and tighten up the bolt. You can also use this method to adjust the direction of the seat in relation to the handlebars, left or right.
If you need the seat adjusted for its angle. Under the seat itself are two bolts clamping two large circular bits of metal, undo these bolts and tilt the seat downwards or upwards, retighten when you have it just right.
