How to Install an Old Bicycle Speedometer

How to Install an Old Bicycle Speedometer
Before wireless speedometers became available, cyclists used wired speedometers to keep track of speed, distance, cadence and altitude. Both types of bicycle computers are available as of March 2010, but the older wired speedometers require different instructions and installation methods.


Difficulty: Moderate

Things You’ll Need:
  • Instruction manual
  • Cable ties
  • Speedometer mount
Step 1
Attach the old speedometer to your handlebars using a cable tie. Remove the speedometer from the mount before attaching and then snap it into the mount later. This will prevent any scratches to the device as you secure the mount. Pull the cable tie, so it is taut.
Step 2
Protect the speedometer wire by routing it down the rear side of the shock. Shock compression will cause the wire to bow out, so ease the wire toward the outside of the shock to prevent the wire from being pulled by your front wheel when it is moving. Secure the wire with a cable tie, but leave enough slack for the front wheel to spin freely without pulling on the wire.
Step 3
Attach the detection wand at the rear of the front fork of your front wheel. Attach the mounting clip 6 inches from the wheel hub and position it in a downward position.
Step 4
Secure the magnet to the spokes of your bike. Make sure the magnet passes the detection wand that was installed about ¼-inch from the detector's tip when the wheel is in motion.
Step 5
Snap the old speedometer into place on the mount, which is located on the handlebars. Hit the "Reset," "Start" or "Power" button. Spin the front wheel to check for a reading.

Tips & Warnings

Always refer to the manufacturer's instructions when there is a problem with an older model speedometer.
Secure all wires to prevent an accident.
