You will need
  • Speedometer, AA battery
Install speedometer gauge (included must be the special rubber bands or clamps). You may need to flip the bike and remove the front wheel.
Attach the magnet of a speedometer on a Bicycle spoke. It is important that the distance from sensor to magnet was about 1 cm and during rotation of the wheel they were on the same level. It does not matter at what distance the magnet is from the axis.
If the speedometer is wired, the wire should immediately peatnut to the future site of attachment of the speedometer and check to see if the wire rubs on the tyre, not whether in the spokes.
To attach the stand to the speedometer on the handlebar.
Fixing the speedometer on the stand, spin the wheels to check the performance.
