The Spinner bike computer consists of the following: 
•

total distance and elapsed time. The computer receives signals from both the cadence unit and 
a heart rate strap. 
 
 
•
Mounting Bracket and Inserts – mounts onto V-Bikes and Pro-Bikes. The thicker wall insert is used on the V-Bike 
bracket assembly. While the thinner wall insert is used on the earlier versions of the Pro-Bike (i.e. Johnny G series).

Cadence sensor - mounts under the left (looking from back of bike) flywheel mount. It

Cadence sensor when it passes by the internal reed switch.
