Tricycle Bikes. Laoag., Bernard Spragg Photo

There are 3.5 million tricycles in the Philippines, and they’re mostly ridden by adults. Conventional motorbikes with metal passenger sidecars welded to their sides, the trikes are one of the many quirky aspects of public life here that delight tourists and, for locals, provide the bulk of public transportation in provincial cities across the country. .They’re also loud and dirty, roaring through the streets and spewing black smoke from rattling tailpipes.
