Bangkok is slowly becoming more cyclable — bike share stations, dedicated lanes, and the best routes.
Bangkok's official bike share system operates around the city — docking stations near BTS and MRT; app-based; 10–30 THB per trip.
Bang Krachao (the Green Lung — the best cycling by far), Chao Phraya Sky Park, Lumphini Park perimeter, Chatuchak Park.
Bangkok traffic is intimidating — stick to parks and dedicated lanes; avoid Sukhumvit and major roads entirely by bike; tuk-tuks and taxis don't yield.
Ferry across from Bang Na or Klong Toei piers; bicycle rental at the landing (80–150 THB/day); marked loop route through orchards and canals.
