A bike computer puts navigation, power and climb data on a screen sized for the bars, with a battery that outlasts most GPS watches on a long ride. Garmin Edge dominates the category, Wahoo and Hammerhead are the established alternatives, and COROS and a group of Chinese value brands now compete hard on battery life and price.
Which bike computer brand suits which rider
- Garmin Edge suits the rider who wants the deepest training and navigation tools, with Rally power pedals, Varia radar and Garmin watches working around the head unit. The Edge 1060 is the flagship at £699.99 / $799.99, and the Edge upgrade guide shows when an older Edge is worth replacing.
- Wahoo ELEMNT suits the rider who wants a computer that is quick to set up and easy to use with gloves on. Wahoo’s button-first interface is easier to use than the touch-designed menus on Garmin’s button-only Edge models. The Bolt 3 is the best first serious bike computer, and the Roam 3 is the better choice for riders who follow a lot of routes.
- Hammerhead Karoo 3 suits the rider who wants third-party apps on the bars. Hammerhead opened its Karoo Extensions SDK in late 2024, and the Ki2 extension brought Shimano Di2 data to the Karoo 3.
- COROS Dura 2 Solar suits the long-distance rider. COROS claims 120 hours of GPS riding, and the Dura 2 Solar adds voice control and named streets on the map. It goes on sale on 3 November 2026 from £429 / $499.
- Magene, iGPSPORT, Coospo and Bryton suit the rider who wants GPS, power and navigation for a fraction of an Edge’s price, and accepts rougher software in return.
Battery or a bright screen
Garmin’s current Edge generation, from the 550 to the 1060, uses a bright transmissive screen, and its demanding-use battery sits between 12 and 20 hours. The Edge 1040 Solar keeps the older reflective MIP screen, runs 45 hours before solar, and gains around 20 minutes per hour in strong sun. A solar layer only works in front of a reflective screen, so the brighter Garmin models cannot carry one.
That leaves two solar bike computers, compared in Dura 2 Solar vs Edge 1040 Solar. The Dura 2 Solar lasts longer on paper and charges faster. The 1040 Solar reroutes on the device and is often discounted. For multi-day events and bikepacking, one of these two is the sensible starting point.
Voice control arrived in one week
Three brands added a microphone within days of each other in October 2026: Garmin with the Edge 1060 and the Edge Explore 3 Plus, and COROS with the Dura 2 Solar. A rider can now reroute, ask for ride data or report a hazard without taking a hand off the bars. On the Edge 1060, that capability costs $100 more than the Edge 1050 did at launch, with the screen, battery and training features unchanged, as the Edge 1060 vs 1050 comparison sets out.
The previous generation is often the better buy
Garmin passes most new Edge software down the range. Public betas 33.13 and 31.67 bring Edge 1060 software, including GroupRide and Garmin Cycling Coach, to the Edge 1050, 850 and 550 and to the Edge 1040, 840 and 540, as reported in Edge 1050 and 1040 gain Edge 1060 features. A discounted Edge 1050 therefore delivers most of the flagship’s training tools, and Edge 1060 vs 850 vs 550 sets out which Edge to buy by rider.
Wahoo grows its computers the same way through sensor support. The ELEMNT ACE, ROAM 3 and BOLT 3 now show core temperature, sweat loss and breathing thresholds beside power and heart rate.
What the value brands get right
The Coospo CS600 looks and feels like a Garmin for under $150, with 36 hours of battery and full GNSS, but it does not match rivals at twice the price. Hardware is no longer what separates the value brands from Garmin and Wahoo. Software polish, mapping and the sensor ecosystem are.
The value brands are closing that gap through firmware. Magene added a ClimbPro-style climb screen to the C606, and the C506 is a sound entry-level unit. iGPSPORT covers the same ground with the BSC300T and the larger iGS800, and riders choosing between these brands most often compare them with each other rather than with an Edge.
Racing and the UCI size limit
The UCI will cap bike computer dimensions at 126 x 71mm in competition from 2028. No current device is banned, but the rule closes off the larger formats the industry was heading towards, which matters to racers weighing a big-screen unit such as the Wahoo ELEMNT ACE.

Quick answers
Which bike computer has the longest battery life?
COROS claims 120 hours of GPS riding for the Dura 2 Solar. Garmin’s longest-running current Edge is the Edge 1040 Solar, at 45 hours before solar charging adds around 20 minutes per hour in strong sun.
Is a cheap bike computer good enough?
A value computer such as the Coospo CS600 records GPS, power and heart rate well and lasts 36 hours. It falls short of Garmin and Wahoo on software polish, mapping and sensor support.
Which bike computers have voice control?
Garmin Edge 1060, Garmin Edge Explore 3 Plus and COROS Dura 2 Solar, all announced in October 2026, take spoken requests for routes and ride data.
