  • Lights and Reflectors: Attach front and rear lights, especially if riding during dusk or dawn, and reflectors for visibility.

7. Emergency Preparedness

  • Tool Kit: Carry a basic bike repair kit with a pump, spare tube, and multi-tool.
  • First-Aid Kit: Include bandages, antiseptic wipes, and other basic items in case of minor scrapes.
