Schwinn Bike Speedometer Instructions

Install the battery. Unscrew the speedometer's back cover with a coin by placing the coin into the slot on the back cover and turning it counterclockwise, as you would a screw. Place the battery into its slot with the positive pole closest to the back battery cover. Replace the back battery cover, using the same coin to attach the cover by placing the coin into the slot and turning it clockwise.

Attach the mounting bracket and computer unit to the right side of the bike handlebars near the fork. The clip faces the bike seat. Tighten the bottom bracket screw with a screwdriver until it holds but is not fully tight. Adjust the bracket to the angle that offers you the best view while riding. This depends on your height and the height of your saddle. Further tighten the bracket screws with a screwdriver. Slide the speedometer computer unit into the mounting shoe until it clicks into place.

Attach the magnet and sensor to the front wheel. Place the magnet between two front wheel spokes, near the wheel's hub, and unscrew the small screw on the back of the magnet. Insert a spoke into the slot on the magnet's back. Screw the small screw back into place. Attach the sensor's cable ties to the bottom of the fork, ensuring that the sensor lines up with the magnet with only minimal space between the magnet and the sensor.

Plug the end of the wire that has an attachment into the sensor. Run the sensor wire up the fork, keeping it in place by using the cable ties attached at the base and top of the fork. Give the wire enough slack that your handlebars can turn but not so much slack that it gets caught in the spokes. Wrap excess wire around brake cables. Do not cut the wire or you will damage the speedometer. Plug the other end of the wire into the computer unit; the remaining end of the wire will have an attachment that fits into the computer unit.

Set the computer functions. The speedometer has two buttons: one on the right side and one on the left. Set the wheel size by pressing both the left and right button for two seconds and then inputting the wheel size by its wheel factor. Figure out the wheel factor by multiplying the wheel's diameter, in millimeters, by 3.1416. Press the right button to scroll through the numbers and the left button to set data once numbers you need are displayed. Choose mile or kilometer readouts with the right button and set your choice by pressing the left button. Set the clock by pressing the speedometer's left button for two seconds. Press the right button to choose a 12-hour (12H) or 24-hour clock (24H). Press the right button again to scroll to the correct hour, press the left button to accept. Press the right button to scroll through minutes and the left button to accept.

Schwinn speedometers will automatically gauge current speed and display it on the top line. Other data appears on the bottom line, where the clock is also displayed. A plus or minus appears in the upper right-hand corner, above current speed, to show if you are traveling above or below your average speed. A small bicycle with wheels turning backward or forward appears in the upper left of the screen to show if you are accelerating or decelerating.

Press the right button to display desired data. Current speed, the plus or minus and the little bicycle will remain a constant on the top line of the display, but you can choose what appears on the bottom line. One option is scan mode, which scrolls through average speed (AVS), trip timer (TM), maximum speed (MX) and trip distance (DST).

Write down total distance if you want to input it after a battery replacement to keep a running total. Press the right button until you get ODO mode, then press the left button for two seconds until the last number along the bottom row starts flashing. Press the right button until you are at the number you need to input your total distance, then hit the left button to save that setting.
