What Is a Bike Computer?
A bicycle computer, also known as a cyclometer or cyclocomputer, is a device that works much like the instrument panel in a car. It attaches to your bike and displays or records trip information.
The information is displayed on the head unit which is generally mounted on the handlebars of your bike. With technology, some smartwatches can also be used as a head unit.
A bike computer will usually consist of four main parts:
Most models of bike computers will display information such as current and maximum speed, distance traveled, time of day, and temperature. More advanced models will also include such information as altitude, GPS data, heart rate and even power output.
Why Use a Bike Computer?
Bike computers are used by every style of rider; from the casual to the course trainer. You can use a bike computer both for fun, and to track your trip distance and time, or you can use it as motivation to be even better next time.
As Veeder Manufacturing Company, the 1895 inventor of the cyclometer, said in their promotion slogan: “It’s nice to know how far you go.”
Benefits of Riding with a Bike Computer
Whether you are riding for pleasure or training for the next Tour de France, the best bike computer has many advantages.
The most obvious of these benefits is in the distance traveled. Knowing how far you have gone helps in training as well as your early morning ride. Coupling distance with time or speed will benefit you by providing motivation to always beat your best.
With the ability to track your heart rate and power production, you will know if you need to change gears for that aerobic workout or taper things off to maintain your preferred heart rate.
Healthy, active lifestyles begin by knowing where you are at and knowing where you want to be. Having a best cycling computers on your handlebars will help you, in real time, know just how far you have to go to get there.
How Does a Bike Computer Work?
A bike computer uses sensors placed in various positions around your bike to send data information to a transmission.
This transmission converts to the head unit computer.
Once the computer has the data, it transforms it into human-readable information and displays it on the head unit LCD screen.
Type of Sensors
There are two types of sensors: magnetic and GPS. Each type has its advantages and disadvantages.
Magnetic sensors are generally used for cadence and speed. A magnet is mounted to the spoke of a wheel or the crankarm. A sensor is then mounted on the frame or front fork of the bike and reads every time the magnet passes the sensor.
Because the magnetic field is strong, these sensors are immune to dirt, dust, water or mud. The accuracy can be counted on in any condition.
GPS sensors use a GPS enabled device to monitor data through GPS signals. This data is then sent to the head unit by the transmission to be displayed on the screen for the rider.
While the GPS sensors can easily be moved between bicycles, they are more expensive. One downside to a bike GPS cycling computer is that the sensor runs on rechargeable batteries that will need to be regularly maintained.
Types of Data Transmission
There are two types of data transmission from the sensors to the head unit: wire and wireless.
Wired transmission models are simply sensors with a wire that must be attached to the bike frame leading to the head unit.
Besides the tangle of wires that need to be properly installed, the downside to a wired transmission is that they are not easily swapped between bikes.
These are generally lighter units than wireless making them better for light bike needs. However, they are not the best option for mountain bike computers because the wires can come loose, get cut or ripped off the frame.
Wireless transmission uses a signal to send data to the head unit instead of a wire. The best bike computers with GPS are going to be wireless.
Because of their nature, wireless units are generally heavier than wired units. This could be a problem for those looking to save on the overall weight, such as competitive riders.
Road riders will appreciate the inexpensive and durable wired units, while mountain bikers and competitive riders will like the efficiency and reliability of wireless units.
What Bike Computer Measures/Functions
Bike computers measure a lot more than distance nowadays.
No two models are alike and each will come with different features and measurements. Deciding what features you require and what features you want will help you determine the best bike computer for you.
The basic functions of nearly all bike computers are standard. You will find functions and features such as:
A lot of road bike computers and mountain bike computers will offer advanced features. Depending on your riding style these advanced features may prove more useful to you.
Whether you choose wired or wireless transmissions, magnetic or GPS sensors, or basic or advanced functions, each bike computer will have various features. These features will come into your decision on which model to purchase.
Installation and functionality will play a large part in your buying experience. The features listed here will explain what you should look for and the purpose of each one.
Rear Wheel Sensor
Some models will offer the use of a rear wheel sensor.
These usually tie in with the cadence sensor on the crankarm and use a wire mounted to the frame to the head unit.
When looking for a rear wheel sensor, be sure that the model is designed for it.
Most wheel sensors are designed to be mounted on the fork of the front wheel.
Because of the chain, pedals and gears, mounting on a rear wheel can have disadvantages.
You may be required to extend the cable, or if you are using a wireless sensor, it may not have a strong enough signal to reach the head unit.
Unfortunately, we can’t always ride in perfect weather conditions. Having a bike computer that is water resistant is an important feature to look for.
While your sensors are generally going to be weatherproof (especially the magnetic sensors), the head unit may only be water resistant. You should ensure that it is rated for water resistance and take the needed precautions when riding in the rain or after a rain shower.
Checking your head unit for cracks or damage should be a part of your pre-ride routine. Having a head unit short out because of water damage will not only cost you money, but it won’t be able to record your data for that ride.
A lot of the best bike computers will offer the advantage of paring with your smartphone. Either using apps or monitoring.
While smartphone pairing is still less accurate, you can use a smartphone, or smart watch instead of a head unit. This is a great feature if you want to take your progress with you even when you aren’t on a bike.
When using your smartphone as a head unit, you have certain advantages such as a larger display and easy to read mapping capabilities. However, you will need a special mount for the phone and without the proper case, there will be less weather resistance and greater risk of damage in an accident.
GPS features give you a lot more data capabilities than standard types. You can transfer your data to a computer, for example. Using a satellite signal to transmit your ride data is very accurate and efficient.
The downside to bike GPS cycling computers is that they require a strong signal which can be affected by weather, location and availability. Mounting the GPS is easier than standard mounts as there are no wires. This means they can be transferred between bikes effectively.
That alone could save you money by not having to purchase multiple bike computers. The units are heavier, though, and for competitive riders may not be the best option.
ANT+ is a wireless technology that allows devices to talk to each other. Having an ANT+ enabled bike computer means no wires. Your sensors will fit one of three ANT+ profiles and be able to send data to the head unit using the ANT+ technology.
The most common ANT+ profile is speed/cadence combo sensor. Without fail, if a device is ANT+ capable it supports this profile. Speed only and Cadence only are still new ANT+ profiles and may or may not be supported by your device.
You should ensure your device and sensors can support the required ANT+ profile for your particular application.
There are also other ANT+ profiles for other devices that can be used with your head unit. Heart rate monitors, skin temperature monitors and even electric bikes.
Most non-casual riders have more than one bike. Different terrains and different needs require different equipment. However, you can find options for best cycling computers that allow you to use multiple bikes.
Any GPS unit will quickly move to another handlebar. There are also bike computers on the market designed for multiple bikes. When using the same device for multiple bikes, you need to have a few extra pieces.
The mount should stay on the handlebar, so you will need multiple mounts. You should ensure that your unit is multi bike ready. Different wheel sizes and frame distance from sensors to handlebars will affect the units.
Make sure that your device is capable of either manual input for tire size, or can easily be calibrated.
One important feature for night riders, or early morning riders, that is often overlooked is a back light. Most riders already have a headlight on their helmet. However, the glare from the headlight might impede the viewing of the LCD display.
Having a head unit with a back light means you can see it at any time. Not only does a back light provide visibility of the head unit in any lighting conditions, but it is also a safety feature.
By keeping your headlamp on the road as well as your eyes and attention, you can avoid accidents and wrecks.
Multiple Data Screen
Why bother tracking different data if you can’t view it? With multiple data screen capabilities, you can monitor multiple inputs at the same time.
Tracking speed while monitoring the temperature or altitude, can give you real-time feedback on your performance. Likewise, watching your heart rate and cadence together can be useful for training purposes.
Head units come in different sizes and shapes. Being able to read the display quickly and return your attention to the road is important.
If you have less than perfect eyesight, you may need to opt for a larger display. Another option is to pair your device to your smart phone. The bright, vivid display will allow you to quickly keep tabs on your data and your attention on the road.
What to Consider When Choosing A Bike Computer
There are several factors to consider when choosing which is the best bike computer for you. Needs and functionality are among the top factors. However, you should also decide your wants, expectations and even the type of rider you are.
These factors will help you narrow your choice down to the best bike computer for you.
What Type of Rider Are You?
Knowing the type of rider you are will go a long way to determining the bike computer that will best suit your needs. Casual, trails, training or competitive, the best bike computer for you depends a lot on how you will use it.
If you like to torque on the heavy tread and hit the trails, then the best mountain bike computer will better suit you than the best road bike computers.
Likewise, if you are trying to train or increase your cardio workout, then you will be better suited for a road bike computer. Deciding on features is easier when you can narrow down how exactly you will be using your bike computer.
A cycling computer is a great option. However, if you have to save some cash, then a phone will work too.
Garmin is a much more superior option here. It has an easy interface, a simple setup, and the best overall features.
Garmin Edge 520 Plus. is the best Garmin bike computer option for most riders.
You can turn your phone into a bike's computer by using the cycle meter option if you are okay to put your phone between handlebars.
Mount your bike computer close to the hub. The closer you mount, the more slowly it will pass by the sensor, it will offer more time to respond.
So, there you have it. Our rundown of the five best bike computers. With so many options to choose from it can be difficult to know which to choose.
We hope our reviews have helped you make the right decision. If you are a casual rider, a trail monster or a competitive racer looking for an advantage, you need the right bike computer for you.
Track your distance, your heart rate and your miles and train to get better every day. Cycling in today's’ technologically advanced world means more ride data is available to you than ever before. A bike computer makes sense for any rider, from trainer to enthusiast.
