Wireless

The sensor on your bike and the computer communicate using wireless technology. If you don't want wires on your suspension forks, or if you'll be flying on your mtb through trees, where wires could catch, then you'll need a Wireless Cycle Computer.

2.4 GHz / multiband

This is just the frequency that wireless transmits at. If you see multi-channel or multi-band it just means there will be less interference to the signal, caused by other wireless devices. (You may see crosstalk mentioned).

Cadence

The cyclists technical word for how fast your pedals are going in rpm (revs per minute). High cadence is 100rpm, low is 50rpm. Check our Cadence Cycle Computers section for more technical details.

Heart Rate / Zones / RR

Uses sensors to show your heart rate. Often showing zones corresponding to heart rate zones. RR means relaxation rate. Some cycle computers give you information on how you recover from exertion.

Calorie consumption

You can get both cumulative calories used and current calorie burn rate.

Countdown distance

Simply distance left to travel. You can get it in distance or time based on your speed, if you've got GPS. Read all about them here:GPS Cycle Computers.

Lap data

For competitors or for cyclists just going around the same route for the hell of it. You usually get lap distance, time, average speed, number of laps. With some of the top cycle computers you can link two bike's data together to compare.

Odometer

A mileometer ! But usually with more functions that your car one eg. reset, cumulative and part journeys, store data function.

Backlight

Handy in the dark, in subdued conditions or under trees.

Files (number of files)

This tells you how many sets of data your device will store.

2nd. Bike

Some Cycle Computers allow your device to pick up data from someone else's bike as well as your own. Very useful for team training.

Tyre size options

Worth checking if you rely on distance measurements. You'll need to set the tyre size.

Speed options

Typically current speed, max speed and average speed.

Trip distance

Part of your odometer options for giving you a variety of information about your cycling journey and route.

Power saving / Sleep

An important option if you're travelling long distances where you don't need continuous information, so you don't unexpectedly get stuck somewhere with no spare batteries and no charging facilities.

Waterproof or Splash proof

Very important if you're competing or cycling in all weathers. Not all Cycle Computers are waterproof, some are only splash proof !

Power or Energy output

Gives you a continuous reading of power output using a combination of data. Essential if you are following a training program.

Cycling efficiency

Knowing exactly what is being measured with this can be quite tricky, depending on what your understanding of efficiency is. However, very useful for serious training where you want to compare your own performances on different occasions, or measure the effect of different training regimes.

Limits

These can be settings on many of the measured data your Cycle Computer shows you. If you're training, make sure that your computer gives you the limits you might need to set eg. heart rate, speed, energy output.
