In today’s data-driven world, a cycling computer or speedometer is almost a necessity for any cyclist. They not only display your current speed, trip distance, and duration, but there’s much more to it nowadays especially if you’re a data geek.

Some of the most common questions cyclists have are;

  • Are bike computers worth it?
  • Which one should I get?

My answer is, it depends on your needs. There are those basic ones that cost less than $100, mid-level and premium ones that go as high as $300+.

How We Pick Bike Computers

When it comes to bike computers, the market today is dominated by Wahoo and Garmin. It’s no surprise then that the majority of cyclists in our local bunch use models from either brand. 

But if you look harder, you’ll soon realize there are several more brands out there. We researched them on large cycling retailers such as Competitive Cyclist, Wiggle and Amazon, then filtered out those with below average (3.5/5 and lower) user reviews. That leaves us with a handful of bike computers.

From there, we applied the criteria that we set out below to come up with this list.

  • Price Range. Bike computers can range from $30 all the way up to $300. For this list, we picked models across the price points, from basic (sub $100), value for money, mid-tier ($100 to 300), and premium range ($300+).
  • User Friendliness. We prefer models that are easy to use with intuitive navigational menus in order to access all the features and functionalities.
  • Battery Capacity. These days, bike computers should have at least 10 or more hours of battery life before needing a recharge. Generally, the larger and more vibrant the screen is, the more battery it will consume.
  • Features and Connectivity. Functionalities such as Wi-Fi, Bluetooth, and ANT+ are ubiquitous across many models these days and allows for seamless integration with apps such as Strava for ride logging and Ride with GPS for navigation.
  • Screen Size. Some cyclists want to have a lot of data fields displayed on their screens while riding. A large screen bike computer is ideal for this as all the data can be displayed clearly.

Frequently Asked Questions

Bike computers can be a very complicated piece of gadget as they become more feature-rich and advanced. We’ll try to address some of the most commonly asked questions among cyclists below.

Is there a cheaper option?

Yes there is. 

In fact, you can use your smartphone to function as a bike computer. Most cyclists today bring their smartphone with them while riding and using the smartphone is a very popular choice among commuters.

Just install apps like Strava and it can track your current speed, riding distance and time.

You’ll also need to get a secure and reliable phone mount to mount the smartphone on the handlebars.

Do I need to buy cadence and speed sensors?

You’ll need speed sensors if your bike computer doesn’t use GPS. Cadence sensors are optional.

Speed sensors. If you look around, most premium ones come bundled with cadence and speed sensors. These are nice to have especially the speed sensors.

Your speed is computed using the GPS signals. The only time the speed sensor comes into play is when you’re riding in areas without GPS signals such as through tunnels.

However, if you’re using one without GPS capabilities such as the Cateye Padrone, then the speed sensor is critical to measuring your speed.

Cadence sensors. The only time you’ll really need a cadence sensor is if you’re training to a specific cadence. Otherwise, it’s a nice to have to be able to see how fast your legs are spinning, and that’s just about it.

Can I sync the bike computer to my smartphone to view my training data?

You can sync to your phone as long as they support Bluetooth (or WiFi for newer, more advanced models).

For this to work, you’ll also need to install the companion apps such as the Garmin Connect, Wahoo Elemnt or Lezyne Ally on your phone.

Once synced, it can display things like incoming calls (useful to know who’s calling you mid-ride without taking your phone from the back pocket) and messages during your rides.

Once you’re home, you can sync the ride data with services such as Training Peaks, Strava, or Today’s Plan to view and analyze your training data.

How do I sync my rides to Strava?

Strava and Garmin Connect

These days, synching to Strava is almost seamless if the bike computer has Bluetooth and WiFi connectivity built-in. You’ll need to link the it to Strava during the initial set up phase and voila.

Each time you finish your ride, it will automatically upload the ride data when it’s connected to your home wifi or via your smartphone’s Bluetooth connection.

If you’re using a basic one, you’ll probably need to download it to your computer via USB, and then manually upload the .fit or .gpx file.

Can I use a bike computer on an indoor trainer?

Yes you can for a bike trainer that supports the ANT+ FE-C protocol such as the Garmin Edge 830, Garmin Edge 1030, Wahoo Elemnt Roam and Bolt.

FE-C stands for Fitness Equipment – Controller, which is a communication protocol developed for bike computers/apps to talk to fitness equipments, such as a trainer.

You can use your bike computer to do several things on a smart trainer :

  • Ride a virtual course. You can create the course on apps like MapMyRide or RidewithGPS, load it onto the bike computer. It’ll then adjust the resistance on the trainer to mimic the gradient of the route.
  • Ride a previous workout. You can re-ride a course you’ve ridden previously.
  • Ride a structured workout. Once you’ve loaded the workout, it’ll sync with the trainer to adjust the resistance accordingly. This is sometimes referred to as ERG mode.
  • Ride a manual workout. You can use the it as a controller to manually set the trainer’s power/resistance levels up/down.

Which is better - Garmin or Wahoo?

Both Garmin and Wahoo are the leading brands in bike computers. Garmin was the pioneer and Wahoo is the newer kid on the block and they’ve made very significant progress in the past few years.

Generally, Garmin has a broader range of computers ranging from low to high-end while Wahoo is more from mid to high-end. One important thing to note is that all Wahoo bike computers are non-touchscreen, even for their top-tiered model, the Wahoo Elemnt Roam.
