Frequently Asked Questions

How do I use Rally Radio?

Open the Radio tab and tap "Start Rally Radio." Other riders nearby with the app will automatically appear. Hold the blue mic button to talk, release to stop. Toggle "Open Mic" for hands-free mode.

Does Rally Radio need cell service?

No. Rally Radio works peer-to-peer over WiFi Direct. Both devices need to be within ~100 meters of each other. No internet connection required.

How do I inquire about a bike?

Open the Bikes tab, tap a bike you're interested in, then tap "Inquire About This Bike." This opens an email to our team with the bike details pre-filled.

Are the cycling routes accurate?

Routes are sourced from real GPX files recorded in the Black Hills region. Conditions may change — always check trail status before riding.

Is the app free?

Yes, completely free with no ads or in-app purchases.

Can our bike co-op use this app?

Yes! The app is open source. Visit our GitHub repository for instructions on forking and customizing it for your community.
