GPS Speedometer for Motorcycles, Dirt Bikes & Custom Builds
Perfect for motorcycles, dirt bikes, track bikes, and bikes without built-in speedometers. Mount your iPhone and track speed, distance, and performance.
Why Motorcyclists Choose GPS Speedometer
No Installation Required
No wiring, no drilling, no modifications to your bike. Just mount your iPhone on handlebars with a phone mount and you're ready to ride. Remove it when you park.
Saves Money
Motorcycle speedometer replacement costs $150-$600+. GPS Speedometer is free to download with core features available at no cost. Much cheaper than OEM or aftermarket gauges.
1-2% GPS Accuracy
GPS provides 1-2% accuracy - often more accurate than motorcycle cable speedometers which can drift 5-10% with wear. Measures actual ground speed directly from satellites.
Works Offline
Core speed tracking works without internet or cell service. Perfect for off-road riding, remote trails, and areas without coverage. Once GPS locks, you're good to go.
More Than Just Speed
Track distance, trip time, max speed, average speed, altitude, route history, and G-Force. Features traditional motorcycle speedometers don't provide.
Customizable Display
Choose from multiple themes and layouts. Adjust display for day/night riding. Bigger fonts for easier reading at speed. Customize to match your bike's style.
Motorcycle-Specific Features
The data riders care about — G-Force on the track, altitude on the trail, top speed on the canyon road.
G-Force Meter for Performance
Track acceleration, braking, and cornering forces. Perfect for track days and performance testing. See ACCEL, BRAKE, LEFT, RIGHT forces in real-time.
Max Speed Tracking
Record your maximum speed during rides. Track improvements over time. Compare performance on different bikes or tracks.
Altitude & Elevation
Monitor altitude changes during mountain rides. Track elevation gain/loss. Useful for adventure and touring riders.
Trip Recording & History
Record complete rides with route, distance, duration, speeds. Review past trips. Export GPX files. Perfect for documenting tours and adventures.
Speed Limit Alerts
Automatic road-based speed limit detection. Get alerts when exceeding limits. Useful for street riding and touring.

Important Motorcycle Mounting Tips
Use Vibration-Damping Mounts
Motorcycle vibration can damage iPhone cameras, especially on high-displacement bikes. Use mounts with vibration dampening or silicone isolation. Consider RAM mounts or similar motorcycle-specific options.
Weather Protection
Use waterproof phone cases or mounts with weather covers. Protect from rain, dirt, and debris. Consider a Ram Mount X-Grip with waterproof case for all-weather riding.
Power for Long Rides
GPS uses battery. For long rides, use a motorcycle USB charger. Many modern bikes have USB ports, or add an SAE to USB adapter to your bike's battery.
Security
Remove iPhone when parking. Use quick-release mounts for easy removal. Don't leave expensive phones unattended on your bike.
Screen Visibility
Maximum screen brightness for sunny riding. Consider anti-glare screen protectors. Position mount to minimize sun glare.
