Whether you’re a professional cyclist or just bought your first bike, cycling computers are an essential accessory everyone should own. You don’t have to spend a fortune to buy one though as there are a lot of non-mainstream brands that offer sub $100 GPS computers. In this review we’ll be looking at one of those, the iGPSPORT iGS320 cycling computer. This is iGPSPORT’s latest computer and has a minimalist design and affordable price point. The iGS320 retails for $79.90 and features a high-contrast 2.4” LCD screen. Although it has a limited segmented display screen, iGPSPORT has incorporated turn-by-turn directions into the computer. The computer also features a 1000 mAh battery with a claimed 72 hour runtime with USB Type-C charging port. Additionally the computer uses a widely compatible Garmin quarter-turn style mount.

Where to Buy (US)iGPSPORT


The iGS320 comes in a bright white and orange cardboard box with specifications printed on it. Simple cardboard dividers inside the box separate the GPS computer from the accessories. Inside you’ll find:

  • iGS320 GPS computer
  • USB Type-C charging cable
  • O-ring style handlebar mount
  • User manual

iGPSPORT also offers a full range of accessories and sensors that can be used with the iGS320.


To attach the iGS320 to your bike, iGPSPORT has incorporated a standard Garmin quarter-turn style mount into the base of the computer. It’s a simple puck style design with tabs that extend on each side that connects with a 45 degree rotation that can be found on a variety of bicycle accessories. The computer comes with a basic o-ring style mount that can be attached to handlebars or stems. Although the mount works well, we’d recommend an out-front mount such as the Topeak UTF mount or iGPSPORT’s own M80 out-front mount. The M80 is a plastic mount that retails for about $9.99 and helps place the computer directly in front of the stem for a cleaner installation.


The iGS320 has a traditional rectangular plastic profile with the battery integrated underneath the screen. There are no visible screws or hardware on the computer which gives it a more premium feel. On the front of the iGS320 you’ll find the iGPSPORT logo on the slightly angled edges. The 2.4” LCD screen is well sized and has a glossy finish. iGPSPORT also boasts that the computer has a laminated screen which helps improve the clarity of the screen and reduce glare. To split up the otherwise semi-gloss black body there is a glossy black accent along the base of the computer.

Despite the claimed 72 hour runtime, the iGS320 has a fairly sleek profile with Garmin quarter turn mount.

Underneath the computer you’ll find the Garmin style quarter-turn mount molded into the body of the GPS and the USB-C port below it. A simple rubber gasket cover protects the USB-C port from water and debris. We’re happy to see both the Garmin style mount and USB-C charging port on the iGS320 as they are modern interfaces that allow the computer to be used with a variety of existing accessories. Note, the USB-C port is not USB C2C compatible though, so you’ll need to use the included charging cable or other standard USB-A to USB-C cables to charge the computer.


Being a lower-end GPS computer, it’s not surprising that the iGS320 doesn’t offer much in the way of customization. Instead, the GPS configuration menu only has five basic pages marked as E1-E5. Again, due to the segmented LCD display the UI is highly restrictive so each configuration page has minimal icons or titles to indicate what you’re doing. The five options are:

Pairing (E1): Visually the page display looks like it says “PIAA” but in actuality it is “PAIR”, it’s just a limitation of the segmented style screen in differentiating between a capital “A” and “R”. Aside from that confusion (note iGPSPORT should have used mixed cases to avoid this with “PAIr” instead), this step is needed to connect your cellphone to the computer the first time you pair the iGPSPORT app. You should see a prompt on your phone to confirm the pairing, similar to pairing to a car infotainment display. After that, you shouldn’t need to re-enter this mode unless you change phones.

Timezone (E2): Set the timezone for your location. Aside from the “00:00” display and page label there aren’t any other hints at what this option does. This is automatically calibrated using the GPS signal as well.

Sensor Pairing (E3): Using ANT+ and Bluetooth connectivity, the computer will search for any nearby heart rate / cadence or speed sensors. Note, power meters are not supported with this computer. We had no trouble connecting to our Bryton cadence sensor.

Wheel Circumference (E4): Set the wheel circumference in mm. This is only needed if you use a speed sensor to ensure the speed and distance values are computed correctly. The included user manual has a table with wheel / tire size combinations, and you can easily measure this with a ruler by marking a spot on the wheel and moving the bike in a straight line until the same mark touches the ground.

Display Units (E5): Select between metric (miles / Fahrenheit) or imperial units (km / Celsius) for the distance and temperature display.

iGPSPORT iGS320 Cycling GPS Computer Review - Config Menu
Due to the limitations of the LCD display the iGS320 has some confusing configuration menus with limited descriptions.

Aside from the confusing “EX” page displays, the configuration options are easy to use. The most frustrating part about that is that the bottom right button is used to save your selection and exit the menu. That means you always have to re-enter the configuration menu to do another configuration option change. Also, the computer automatically exits the configuration menu after 10 seconds of inactivity so you’ll need to work relatively quickly. The configuration menu is very similar to the CYCPLUS M1 and M2 computers and one of the main limitations of this style display.


Although the iGPSPORT iGS320 is an entry-level computer with its sub $100 pricing, it does offer a few unique features that are worth highlighting.

Turn-by-turn Navigation: Any sort of navigation is rare to see at this price point so we were surprised to see it here. Unfortunately, the limited segmented display design means the iGS320 has no map or breadcrumb style display. Instead the navigation feature is limited to a small data field in the top left that will show distance to the next turn or an off-course symbol. The lack of street names or even a basic bread-crumb style display makes the navigation feature essentially unusable unless your route is easy to follow. There is also no rerouting, so if you do end up off course the navigation essentially stops. Setting up a route requires connecting to the iGPSPORT app and uploading a route directly to it. The computer does not save routes, so you need to upload the route to the computer before you want to use the feature.

Live Tracking: This is a similar feature to Bryton S500 and other computers on the market that allows you to share your GPS location to a selected list of email addresses. You’ll need to use the app to set the recipient list and activate the tracking feature. If that is setup, then the recipients on the list will receive a web link as soon as you start recording a ride. It’s a great feature to use if you have a significant other at home or trying to meet up with others mid ride as you can quickly see the last known GPS location. One improvement we’d like to see is an option to send additional people the location after a ride has started instead of having to pick the recipient list before starting the ride.


The iGPSPORT iGS320 has a simple non-touch screen display with two physical buttons on the bottom edge. Both buttons are large and have great tactile feel which means they can easily be used with gloves on. Red coloring on the left button helps highlight the fact that the button is used for turning the computer on and off. The short press on the right button cycles through the three screen displays while holding the button activates the configuration menu. Although most computers use a three or four button interface, the two button design of the iGS320 works well as the interface is straightforward. The only potential downside is that iGPSPORT has dropped the lap function which some cyclists may find useful.

The iGS320 has two large physical buttons with an intuitive user interface.


As with most computers on the market, the iGS320 can be paired with iGPSPORT’s app. It’s a free app that’s available on both Google Play and Apple’s App Store. The app has a simple four tab design that displays a home screen, activity log, device manager and a user profile. You’ll need to create an account before you can access the app but once you’ve logged in the interface is intuitive. You can review previously recorded ride metrics, monitor mileage by week/month and even set goals for extra motivation. While the app design and layout is well done, there are little bugs such as Chinese character displays on some fields and some slow load times when viewing activities.

The main reason to use the app is to enable auto-syncing between the computer and third party tools such as Strava which have better ride analysis and sharing platforms. Also the navigation feature of the iGS320 does require using the app to create and upload routes to the device. Route creation is a clumsy process that requires creating multiple waypoints by aligning the dot at the center of the map to the desired location. Unless you are setting up a simple route, we’d recommend using the import feature instead. You’ll need to upload the route to the computer before you can use the feature as the iGS320 does not store routes.


Overall, we found the iGPSPORT iGS320 to be an easy to use GPS computer with a high contrast display. The simple segmented LCD display is easy to read with a black text on white background that works well in low light or direct sun. We also found the two button interface and simple menu structure easy to navigate. The budget friendly price of the iGS320 makes the computer more accessible but does mean the computer lacks layout or data field customization. While we were impressed to see that the iGS320 offers turn-by-turn navigation, the basic turn and distance display is essentially not usable as there is no map view or even a simple breadcrumb view. That said, the combination of the budget friendly price, USB-C interface and Garmin style quarter turn mount make the iGS320 a good entry-level computer.

  1. Can you tell us more about the M80 mount?
    Is it stuff enough to carry a bike computer and a GoPro at bottom, AND not wobble?

    1. The M80 is just a simple plastic out-front-mount, it’s only one-sided so you can’t mount something under it. At $10 it’s a decent mount but its thicker than metal equivalents. if you want to carry more gear, I’d recommend the Topeak UTF or Magicshine TTA dual-sided metal mounts. Otherwise there are a lot options on the market for dual-sided mounts.
