Bike Computer FAQ
Now that we’ve given you our picks of the best bike computers, it’s time for us to further examine some of the most asked questions about bike computers. We searched the internet, looking for the questions that most riders ask about bike computers, and we’ve compiled them all here.
Then, we researched the answers to these questions, and put all the handy information that you need, right here, in one place. You don’t have to do the work, because we’ve already done it for you.
How Does Bike Computer Work?
Here’s a fun bit of history about bike computers. The first bike “the computer” or cyclometer was invented in 1895. Curtis Veeder developed a simple device that would count the number of rotations of the bike wheel.
Using a cable the count of the revolutions was sent to an analog odometer. The rider could use the number of revolutions counted, to determine the distance traveled, using a simple formula.
While the early cyclometer was super simple, it offered the same advantage to the rider that today’s bike computer does. It gave helpful information about the distance traveled.
Today’s bike computers do much more, however, their basic operation hasn’t changed much. The modern bike computer is made of a group of components, each of which makes the operation of the computer possible.
The head or display is the brain of the bike computer. It takes the signal sent from other components and translates it into information such as current speed, average speed, distance traveled, riding time, and the clock time.
More advanced computers may also provide heart rate, incline, altitude and weather details such as temperature. The rider can switch between the information displayed by pushing buttons that are on the head.
Usually, the head is fairly small, and will only display one value at a time. This small size keeps the bike computer from being too much of a distraction to the rider and keeps the rider’s vision unobstructed.
The information regarding things like speed and distance comes from the wheel sensor. The traditional wheel sensor uses a magnet attached to the spokes or hub of the bike wheel, combined with a magnetic reed switch. The reed switch is attached to the fork or back of the frame.
When the sensor on the wheel passes by the reed switch it counts the revolutions. Just like with the original cyclometer, the computer receives the count of revolutions and converts that information to distance, speed, and revolutions.
In order for the sensor to work properly and provide accurate information, the computer needs to be calibrated with information about the wheel size.
The cadence sensor is similar to the wheel sensor. Some bike computers may come with a cadence sensor instead of a wheel sensor.
The cadence sensor magnet is attached to the crank arm of the bike, with the sensor attached to the bike frame. The sensor measures the revolutions per minute of the crank arm, instead of the revolutions of the wheel.
The transmitter is the mode used to send the information from the sensor to the head. In the case of bike computers, there are two types of transmitters, wired or wireless.
If you are using a wired version, the information from the wheel or cadence sensor is transmitted through the wire to the head where it is converted to useful data. If you are using a wireless transmitter, the signal is sent through an unwired signal to the computer head.
While your bike computer provides you with incredibly useful information, they are relatively simple pieces of equipment. And though your modern bike computer provides you with a great deal more information, they still work in a similar manner to the cyclometer first invented by Mr. Veeder
Which Is Better Wired Or Wireless Bike Computer?
There are advantages to both the wired and wireless bike computer. Which you select really depends on your riding style, the type of information you are looking for and of course how much you want to spend.
Wired bike computers are the simplest of computers, and they tend to have fewer issues with recording data. The wired connection gives you consistent readings from the beginning of your ride to the end.
You rarely have to worry about the connection between your sensor and your computer head failing you in the middle of the ride. Wired sensors also function on a single battery.
When you need to replace the batteries on your bike computer, you only need to replace the one on the computer display. The downfall with wired bike computers is the wire.
If you don’t mind dealing with another cable on your bike, a wired computer is a good option. Wired bike computers tend to be a bit more affordable, so if you are on a budget, you may prefer this option over the wireless.
However, if you are frequently riding challenging terrain, or if you don’t like the idea of another cable lacing its way across your bike, the wired bike computer isn’t your best option.
Wireless bike computers are no less accurate than a wired computer. They provide the same information as a wired computer, without the wires.
If you are riding challenging terrain or single-track with lots of trees, a wireless computer will provide you fewer things to catch on branches or rocks.
The downfall of wireless computers come with connections. Sometimes wireless computers tend to lose connection with the computer. This can result in inaccurate measurements of time and distance. This can also happen if the sensor or computer battery goes dead while you are riding.
This is the other downfall of wireless bike computers, instead of a single battery to replace you will need to replace the batteries in both the computer and the sensor.
Finally, wireless bike computers are more expensive. They do a great job of measuring your ride, but you’ll spend more for them. If you are on a budget, a wireless bike computer might not be the best option for you.
How Does A Wireless Bike Computer Work?
A wireless bike computer works in much the same way that wired bike computers work. They are composed of a display unit or computer head, a wheel or cadence sensor and a transmitter.
When you install a wireless bike computer on your bike, you first install the computer head or display. Then you will attach the sensor to the bike’s wheel, either on the spokes or on the wheel hub. If you are using a cadence sensor, you will attach the sensor to the bike crank arm.
With the sensor attached, you will calibrate the display with the sensor, using the wheel size or crank arm rotation. During calibration, you will also set up the computer so that it “talks” with the sensors. Each brand of bike computer will have specific instructions on how this is done.
As you ride, the sensor will count the rotations of your wheel or crank arm and convert that count into the distance. This information will be shown on the computer display.
Some riders have noted concerns with wireless bike computers not being as responsive as wired computers or needing to be restarted if you stop in the middle of your ride. However, these are not huge issues if you are aware of them, and make adjustments as necessary.
What Bike Computers Work With Strava?
Strava is a great smartphone app that has become popular with cyclists and runners alike. It provides an easy way to track your activities, using a connection with your bike computer and your smartphone. Strava is a great way to take your training to the next level.
This great mobile app will track your ride and then break it down mile by mile and tell you important details about your performance.
This allows you to improve your ride, and push harder through the tough parts of your ride. Strava also allows you to connect with other bike athletes, sharing your rides through social media.
This connectivity with other Strava users allows you to create a community of supporters that will encourage you through your workouts and share details of their own workouts. It’s a great way to create accountability when you’re having a rough patch in your training.
However, not all bike computers, heart rate monitors or GPS units will connect with Strava. If you are already using the app, but want to take your ride tracking to the next level, you will want to be able to connect your app directly to your bike computer.
Strava will connect with most of the popular cycle computer brands, but for best results, and to ensure that you select the right computer to sync with your Strava app, you should check the Strava website first.
This will ensure that your bike computer and the Strava app will be compatible and sync easily without a ton of extra effort. Some of the most popular brands that are compatible with the Strava app include:
- MIO Cyclo
Each of these brands has a variety of models that will be compatible with the Strava app. If you don’t see the brand of bike computer that you use on this list, check the Strava website.
More computers and fitness trackers are added to the list of Strava compatible devices, frequently. Before you buy, make sure you reference the Strava website to ensure compatibility.
Also, before you buy, make sure that you know the process for syncing your device with the Strava app. This can be more complicated with some devices than others.
If you are looking for an easy connect, it is suggested that you research the device and its connection process first. That way, you don’t buy a device that stretches the bounds of your computer or smartphone literacy.
How Precise Are Bike Computers?
Despite the simplicity of their function, bike computers tend to be exceptionally accurate. Achieving an accurate measurement may be important for a variety of reasons.
You may be on a racecourse and need to know the exact distance between turn-offs, or you may be trying to accurately measure your own performance as you are training for a race or increasing endurance over longer distances.
Whatever your reason for needing accuracy in distance measurement, you want your bike computer to be as accurate as possible. Because they only have three functioning parts, there are few extras that can create variability in the measurement made by your bike computer.
In general, so long as there is nothing to change the motion of the wheel, the digital bike computer will usually give you the same reading every time for the same number of turns of the wheel.
Most bike computers are accurate within 2 to 5 percent. This variability has more to do with variations in the rotation of your bike’s wheels, than the actual function of the device. Some of the factors that will impact the accuracy of your bike computer include:
- Changes in wheel circumference. This could be caused by the installation of a new wheel, tread wear, the weight of the rider, and the surface conditions.
- Skidding due to pedaling and braking.
- A calibration error in the computer.
- Rounding differences in computer brands.
- Conversion errors in converting kilometers to miles.
- Failure of the wheel magnet to trip the sensor.
- Double counting of wheel revolutions.
- High speeds that the computer cannot keep up with.
- Low speeds that confuse the computer.
- A weak battery
To improve your accuracy there are steps that you can take that are simple and do not take much time, but can make a huge difference in how well your bike computer tracks and measures distance.
- Calibrate the computer frequently to eliminate variability due to tire and tread wear, surface conditions and wheel size.
- Change batteries on both the computer and sensors (if your system is wireless) frequently.
- On-road bikes, move the sensor to the front wheel to eliminate variability from skidding and braking.
- Use the distance units that are recommended by the manufacturer, this will eliminate the need for the computer to convert from one unit to the other.
Taking these simple steps can improve your computer’s accuracy from 5% to close to 1%. This can make a huge difference in your ride performance or locate race features like turn-offs and checkpoints.
How Accurate Is GPS For Measuring Distance?
Compared to your bike computer, you may find that using your GPS unit provides you with significantly less accuracy. GPS units have their purpose, and they can be helpful in a variety of situations.
However, if you are interested in the most accurate tracking of your daily bike rides and want to monitor things like speed and cadence, you will be better served with a bike computer over your GPS unit.
The difference in accuracy between your bike computer and a GPS unit lies in the way distance is measured. With your bike computer, distance is measured by counting the actual revolutions of the bike’s wheels.
This factor is converted to miles using a basic conversion calculation that is programmed in the bike computer. Most bike computers will give you a measurement down to 1/100th of afoot.
Even though there are things that can create variability in this measurement, you can anticipate an accurate distance, with your bike computer, within a couple of feet.
GPS units utilize your position on Earth relative to satellites in space. GPS technology has come a long way in the last few years, but there is still a long way to go when it comes to pinpointing accuracy.
Most GPS units can give you an accurate measurement, but it may not be as close to where you want to go as your bike computer.
Depending on how much you’ve spent on your GPS unit, distance can be measured accurately within 5 to 10 feet. While this is still very close, it just doesn’t compare to the on the ground measurement that you achieve with your bike computer.
Bike computers are a great way to track your ride performance or just to have a better understanding of how far from home your daily ride takes you.
