About Bikel

Bikel is a decentralized cycling tracker built on the Nostr network. It records rides as NIP-1301 fitness activity events linked to the rider's cryptographic identity, which can be used across different clients and relays. It includes an Android tracker with offline drafts and photo overlays, a web dashboard for maps, RSVPs and data exports, plus a relay and a bot for prize pools, scavenger hunts and bitcoin payments. Running the parts requires Docker, npm, and Android build steps.

Key features

  • Passive ride tracking with photo overlays via React Native Android app
  • Offline-first ride drafts with GPS polling and tail-trimming option
  • Map dashboard with ride overlays, RSVPs, and CC0 data exports
  • Scavenger hunts grouping multiple checkpoints into reward sets
  • Sponsored checkpoints paying sats on 50-meter radius entry
  • Self-hostable relay, web frontend, escrow bot, and APK components
Best for: Cyclists, race organizers, and sponsors interested in Nostr-based ride tracking and reward challenges.
Good for
  • Ride data is tied to Nostr identity and usable across clients and relays
  • Android tracker works without Google Play Services, including LineageOS and GrapheneOS
  • Relay, web, backend, and APK are provided as separate self-hostable components
Watch out for
  • APK sideloading requires the phone on the same WiFi network with USB or wireless debugging enabled
  • Running the components requires Docker, Node/npm, and Expo/Gradle build steps

Bikel FAQ

How is ride data stored?
Rides use Nostr time-based events and NIP-1301 fitness activity events linked to the user's cryptographic identity for use across clients and relays.
How do sponsored checkpoints and scavenger hunts work?
Sponsors create individual checkpoints and group them into hunt sets. Entering a checkpoint radius can trigger a sat payment, and completing all points in a set can trigger a set reward.
