How Much Bike Computers Cost?
There are three categories of cycling computers. This depends on the price vs features.
- Basic and Budget (Below $100). Basic models are ideal for beginner cyclists and those who know they don’t need advanced features. These only have basic displays with speed, distance, ride duration, and time. It’s unlikely they’ll feature much connectivity beyond USB support. But again, it shouldn’t be much of an issue if you only need basic data.
- Mid-Range ($100 to $300). Those who desire a wider range of features will opt for a mid-range one. You get a bigger, customizable, and sometimes color and touchscreen too. They come with navigation functionalities, wireless connectivity such as Bluetooth, ANT+, Wi-Fi for you to upload your rides to third-party platforms such as Strava.
- Premium ($300+). These are flagship models for those who want the full suite of features akin to those found on a smartphone. They have advanced navigation, training modes, increased storage options, longer-lasting batteries, sharper displays, bigger screens, and much more.
What to Look for in A Bike Computer?
Bike computers can cost upwards of $300 for a premium model. Before you spend hundreds of dollars on bike computers, here are some important things you should know.
After reading this buying guide, you’ll be able to better determine if it’s wiser to buy a basic model, or you’ll need a more advanced model.
- Display. Most bike computers today have a screen size between 2.3″ (small) to 3.5″ (large). A larger screen allows for more data fields but at the expense of weight and battery life. If you use the bike computer often for navigation, you want to have a color screen to differentiate between the roads and paths. Mid-range to flagship cycling computers such as the Garmin Edge 830 has a color touchscreen.
- User-friendly interface. The model that you decide to buy will come down in large part to the type of interface you prefer and how easy to read the data fields and use. Some models come with customizable screens with various data fields while some aren’t. They also range from full touchscreen to button operated, with some a hybrid of both such as the Hammerhead Karoo 2.
- Battery capacity. If most of your rides are seldom more than 4 to 5 hours long, you won’t need a large battery. You can always charge them post-ride. The Wahoo Fitness ELEMNT Bolt and Bryton Rider 420 have a battery lifespan between 8 to 15 hours. You will get at least 3 to 4 rides done before the battery runs flat. The Lezyne Mega XL has a huge battery that lasts up to 48 hours.
- Wireless connectivity. This is where your individual needs will come into play. Bluetooth and ANT+ connect to accessories such as a powermeter, heart rate monitor, and cadence/speed sensors. If you’re using third-party apps like Strava, then you’ll want one that supports Wi-Fi to upload your rides.
- Bundled accessories (Speed, Cadence, HRM). Mid to high-end bike computers can come bundled with accessories such as a heart rate monitor, speed, and cadence sensors. These are optional, but if you’re a data nerd, you might want to consider getting them. In Garmin’s case, the bundle is optional and you can also buy the standalone unit. Having said that, the bundle is optional. Or in Hammerhead’s case, you can buy their HRM at half price when you buy the head unit.
Frequently Asked Questions
What is the alternative to a bike computer?
You can use your smartphone to function as a bike computer. Most cyclists bring their smartphones with them while riding and using the smartphone is a very popular choice among commuters.

Which is better – Garmin or Wahoo?
