+## 🚲 Bicycle Advocacy 🚲
+
+We believe that cycling is one of the most powerful tools we have for building healthier communities, reducing carbon emissions, and reclaiming our streets.
+
+### Why Bicycles Matter
+
+- **Climate action** — A bicycle produces zero direct emissions. Replacing even one car trip per day with a bike ride can save hundreds of kilograms of CO₂ per year.
+- **Healthier cities** — Cycling reduces traffic congestion, improves air quality, and lowers noise pollution, making urban spaces more liveable for everyone.
+- **Personal health** — Regular cycling improves cardiovascular fitness, mental well-being, and longevity.
+- **Equity & access** — Bicycles are affordable, require no fuel, and open up mobility to people who cannot drive or afford a car.
+- **Economic benefits** — Cyclists spend more at local businesses per kilometre travelled than motorists.
+
+### How You Can Help
+
+1. **Ride when you can.** Every trip made by bike instead of car counts.
+2. **Advocate locally.** Attend city council meetings and support protected bike lane proposals.
+3. **Be visible.** Use lights, wear bright clothing, and ride predictably.
+4. **Welcome newcomers.** Offer to do a group ride with someone new to cycling.
+5. **Support bike-friendly businesses.** Patronise shops that provide bike parking and commuter facilities.
