Many provinces held dry runs ahead of the big day.
In Nakhon Ratchasima’s Muang district, Muthita Kaewjinda, 27, joined 200 two-wheel enthusiasts in the 16km-long rehearsal at Boong Ta Lua Water Park, even though her left leg was incapacitated by a childhood road accident.

This week, Khon Kaen University unveiled what it billed as the “world’s first bicycle made of silk”. The prototype will also be part of the “Bike for Dad” event in the northeastern province.
One of the project’s researchers, textile and innovation expert Sutha Loyduanchai, said the silk used for the frame was light in weight but surprisingly strong. Even though the whole vehicle weighed only 10 kilograms, it could carry about 60-80kg.
Panomkorn Kwakhong, the other researcher and a chemical-engineering lecturer at the university, said this product had been patented and had caught the attention of two groups of investors.
One group wants to make 100 bicycles per day in Taiwan using Thai silk. The other plans to produce handmade bicycles that show off Thai silk patterns. It would require two days to complete one frame.
In the future they hope also to use silk to make the other bike components.
