More people are turning to cycling as a way to stay in shape as well as a means of transportation. There is equipment on the market to help you keep track of just how far you have biked, how fast you are going and how many calories are being burned. One manufacturer of such speedometers is Bell.Bell makes a wireless speedometer that is meant to be mounted on your bike to monitor several different factors. The magnet which holds the speedometer in place should be affixed to the right side of a front spoke. The flat side of the magnet should face out. Remove the tape from the back of the mounting bracket and position the bracket on the handlebar in the spot that would allow the speedometer to be most visible to you. The O-rings included then must be fastened to the underside of the handlebar, the top of the bracket and insert the computer unit to finish installation.Once the unit is installed, it then must be calibrated for use. When turned on for the first time, the unit must be set according to your bike type and the size of your wheel.

For road bikes, the code for 20-inch wheels is '1596.' For 22-inch wheels, it is '1759.' The 24-inch wheels require the code '1916.' The 26-inch wheels use the code '2073.' Finally, 27-inch or 700c wheels use '2124.'As for mountain bikes, those with 24-inch wheels will need input code '1888.' For 26-inch wheels, the code is '2045.' The 27-inch wheeled bikes use the code '2155.' Lastly, 28-inch wheeled bikes would use the code '2237.'Once this is done, select whether you would prefer the distance to be listed in kilometers or miles. Press the right button to toggle between the two. Once you have decided, press the left button to confirm your choice. Similarly, you will need to decide between kilograms and pounds for your weight. Press the right button to choose, and left to confirm. After confirmation, input your weight and confirm it. From here, you will set the clock by pressing the right button and then the left button, once the right time is displayed.

To ensure that the speedometer has been properly installed, spin the front wheel and watch for numbers in the upper left corner to indicate movement. Once it is properly working, you are ready to hit the trails.Bell Bicycle Speedometer Instructions. How to Mount a Bicycle Speedometer Speed Sensor.

A magnet and a sensor unit attached to the front of the bicycle track the movements of the front wheel.

This data is then relayed to the computer, which performs calculations based on the size of the wheel and the number and rate of wheel revolutions.Place one end of a measuring tape at the top edge of one of the bicycle's wheels. Pull the measuring tape across the center of the wheel. Note the distance between the top and bottom edge of the wheel.Press the button on the right side of the bike computer repeatedly to set the appropriate wheel factor. recommends if you are using the computer with a road bicycle, input 1596 for 20-inch wheels, 1759 for 22-inch wheels, 1916 for 24-inch wheels, 2073 for 26-inch wheels and 2124 for 27-inch/700c wheels. If you are using the computer with a mountain bicycle, input 1888 for 24-inch wheels, 2045 for 26-inch wheels, 2155 for 27-inch wheels and 2237 for 28-inch wheels. Press the button on the left side of the bike computer to save your wheel factor setting.Begin pedaling the bicycle to automatically activate the computer. Press the right button to cycle through to the current speed display.

Note the current speed, then press the right button to cycle to the calories burned display. Press and hold the left button to reset the calories burned display, if desired.Press the right button to access the distance traveled display. Note the current distance traveled. Press and hold the left button to reset the display, if desired.Cycle through the trip timer, odometer, average speed and maximum speed displays in a similar fashion. Reset any of the displays, if desired, by holding down the left button.Most bicycle computers use one of six different calibration systems to allow the user to tell the computer what size wheel the bicycle uses.I have used the letters A through F to designate the six different systems in common use.To find your calibration number, refer to the list below to find which is used by your computer. Then, use the chart to find the appropriate value for your tire size (and whether you want readings in miles or kilometers.)If you click on the name of your cyclometer model, you will go to a specific chart for that calibration family.

If your computer is not listed, here, most likely it uses one of the 6 calibration schemes shown. Remove the batteries, wait a few seconds and reinstall them. A calibration number will usually appear. This default value will normally be for a tire in the size range of normal full-sized tires, and if you examine the chart, you should be able to figure out which calibration group to use.Most manufacturers use the same calibration formula for all models, so if your make is listed, but not your model, try the formula listed for other models of the same brand.In addition to the raw calibration numbers, I have on-line instructions for some models. If your computer model name is highlighted on its calibration chart, that is a link to the Calibration Procedure Instructions Page entry that applies to that model.If you want to print out a general version of the Cyclometer Calibration Chart, click here.These values will give a pretty good approximation, usually within 1-2%. If you have a tire size that is not listed, interpolate (split the difference) between the next larger and next smaller sizes listed.
