Using one of the best bike computers can enrich your ride, whether you’re a road cyclist or you enjoy hurtling down mountain bike trails. A cycling computer will keep tabs on where you ride, when, and how fast you ride, among other data. They’re small devices designed to sit on the handlebars of your bike, and can start from under $100 but rise to several hundred dollars for the very top bike computers with GPS and full-fat features.
Three brands tend to dominate the best bike computers arena: Garmin, Wahoo, and Lezyne. As such you’ll find all three in our guide below, simply because they make the best cycling computers money can buy. Wahoo, of course, also makes one of the best bike trainers for training during the off-season - these basically turn your bike into an indoor fitness machine. Though for spin class workouts, we’d still recommend the best exercise bikes.
Once upon a time, Garmin’s Edge GPS bike computers were the undisputed champions, but then came Wahoo with its impressive Elemnt range. Either will see you right, while Lezyne has great bike computers for triathlon training.
For connecting ANT+ sensors, compatibility with lots of services, durability, bike-to-bike communication and more, investing in one of the best bike computers is a smart move. You can buy cycling computers purely for training metrics in addition to wearing a fitness tracker, or splash out on a fully featured device for proper training insight. Here we look at a range of bike computers to suit different budgets and needs.
1. Garmin Edge 530: Best bike computer overall
The Garmin Edge 530 does it all without the top-end price. That means complete connectivity with ANT+, Bluetooth and Wi-Fi, a full color screen with adaptive brightness, a decent 20 hours of battery with optional expansion pack for 80 hours, plus all of Garmin's ever advancing Connect IQ apps. Connect sensors and enjoy Garmin's analytics to help you actually use that data to see visible improvements in performance.
The turn-by-turn navigation is the best you can get on a cycle computer with smart rerouting should you go off track and very clear maps on the color display. The only thing you don't get is touchscreen and address specific routing, but if they're not deal breakers then this is a great way to have it all without breaking the bank.

2. Wahoo Elemnt Bolt: Best bike computer for Strava
The Wahoo Elemnt Bolt is one of those rare GPS bike computers that's been designed to be super-aerodynamic so it's works with your bike. It's also light at 2.2oz and - as you'd imagine from those speed focused specs - it's crammed with features for the serious rider.
The screen might be monochrome but it's super clear and offers turn-by-turn navigation routing with smart rerouting if you go off course. There are also lots of app customizable data fields, with 11 per screen, for the many sensors this can connect to via ANT+ or Bluetooth.
Button controls are fantastically intuitive and this is Strava Live Segment friendly too. If you can live without a color display this is one of the best bike computers you can buy that really gives it all for a lower than top-end price.

3. Garmin Edge 1030: Best bike computer for triathlon training
The Garmin Edge 1030 is the company's flagship bike computer meaning this does it all. It might not be the smallest or lightest at 4.3oz but it uses every bit of that to cram in everything you could want on a ride. That means a large color touchscreen display, ANT+, Bluetooth and Wi-Fi, advanced turn-by-turn navigation that works well plus a 20-hour battery life that can be extended with an add-on pack.
Constant updates with this hardware backing mean you are future-proofed here which helps to justify the price tag on this to-end cycle computer. With Strava, TrainingPeaks and other apps pre-installed plus Garmin's ClimbPro this does it all with a good-looking finish too.

4. Wahoo Elemnt Roam: Best bike computer for navigation
The Wahoo Elemnt Roam GPS is the company's top-end bike computer which means you get a color display as well as app support on this Gorilla Glass protected 3.3oz unit. Aside from the usual data fields, wide sensor connectivity and turn-by-turn navigation you'd expect from a top end device, this has LED light strips for notifications.
These can be set to alert you to turns, training zones and more for at-a-glance information that's ideal for those pushing limits without much time to gaze at a screen. Kickr trainer support and Strava backing make this a very capable device that earns its price easily.

5. Lezyne Mega XL GPS: Best bike computer for battery life
The Lezyne Mega XL GPS has a battery life that leaves the competition long behind, spanning a whopping 48 hours on a charge. Despite this, it still remains lighter than the top-end devices, at 2.9oz yet manages to cram in a 2.7-inch monochrome display that's super clear and can work in both portrait and landscape modes with up to 10 data fields at once.
Connect up to most sensors and trainers with the ANT+ and Bluetooth connectivity but you'll need to upload data via the app as there's no Wi-Fi. This is Strava, TrainingPeaks and Today's Plan compatible and you can upload navigation routes made via GPX files or those made on GPS Root which are stored offline. This does all that and undercuts the competition on price too.

6. Hammerhead Karoo GPS: Best bike computer with cadence
The Hammerhead Karoo GPS is the best looking bike computer when it comes to display. You get a massive 3.5-inch full color and high resolution 229ppi touchscreen on this beauty. That means 12 data fields per page but also beautiful navigation and routing that works really well. SIM onboard means the option to be connected, for new routes mid-ride, without taking a phone.
It works with Strava and TrainingPeaks, connects to lots of sensors including ANT+ and Bluetooth and lets you upload routes from files with over 8GB of storage. The downside is there could be more training plan options for the hardcore rider - but since this is aimed at the explorer type that may not be a big deal.

7. Garmin Edge 520 Plus: Best bike computer on a budget
The Garmin Edge 520 Plus is a great way to get all the excellent Garmin apps and features without spending too much. You still get a full color display, ANT+ and Bluetooth connectivity plus a 15-hour battery life. It just means you can't have Wi-Fi, touchscreen or address specific routing.
Navigation is excellent for turn-by-turn guidance while features like GroupTrack and rider-to-rider messaging are nice live tracking touches. Smartphone notifications are plentiful and you get things like VO2 max and FTP tracking as standard.

8. Lezyne Super Pro GPS: Best bike computer for mountain biking
The Lezyne Super Pro GPS offers the rare-these-days option to view in landscape mode which makes the eight data fields super clear. You can also enjoy clear navigation on the monochrome screen and an impressive 28-hour battery life on a charge.
Controls of the screen via the app are useful and the ANT+ with Bluetooth connectivity make sensor use easy as well as trainer pairing. Strava Live Segments is supported and data will auto sync via the app.

9. Polar V650 GPS: Best bike computer for color touchscreen
The Polar V650 GPS is a full color touchscreen bike computer that isn't damaging to your budget. You get navigation mapping with TOPO maps meaning real lay-of-the-land detail with your routing overlaid. It also means easy access to maps wherever you go.
The downside is limited app support for routing, with it done on a computer and uploaded – but this does support Strava. What it doesn't support is ANT+, as this is Bluetooth only, which could be a deal breaker for those who have already invested in certain sensors. The Flow app has some great data layouts for looking at your progress and updates are regular.
