A free alternative to a bike computer

A dedicated GPS bike computer can cost a hundred dollars or more. For casual riders, a phone in a handlebar mount or jersey pocket is more than enough to track speed and trip distance with very similar accuracy.

Cadence, speed, and pace

This tool focuses on ground speed — the same number a cycling computer shows. Combined with your perceived effort and a watch, it gives you a great picture of how hard you are riding without any special hardware.

Outdoor accuracy

Cycling routes are usually outdoors, which is exactly the condition GPS works best in. With a clear sky, expect speed readings to stay within a couple of km/h of your true ground speed.

Tips for an accurate bike speed reading

  • Mount your phone on the handlebars or stem so the GPS antenna can see the sky — a pocket against your body works less well.
  • Forested trails, tunnels, and overpasses can cause brief dropouts; the average will recover once you are back in open air.
  • Switch to the Analog Dial display if you prefer a glanceable readout while riding.
  • On windy days, your perceived speed and your ground speed can differ a lot — trust the GPS reading.
  • For night rides, switch the page to dark mode using the toggle in the top bar.

For speed, very similarly — they all use the same GPS signal. Dedicated devices add features like cadence sensors, heart rate, and detailed routes, but for a straightforward speed and distance readout, a phone is enough.

No. Vehicle Speed Test only shows live readings during your session. Your location never leaves your device, and nothing is saved when you close the tab.

Use a proper handlebar mount and only glance at the screen briefly, exactly like you would with a bike computer. Never tap the phone while moving.
