BJ has a lot of these cool old school bikes on the streets. they could even be pre-WWII. You obviously can't get them in the stores, so i just offered some old guy 100 kwai for one, while shopping for veg in the morning market. It was a surprisingly easy deal considering i was gesticulating more than i was speaking.
My cousin thinks the ol' guy got the better end of the deal, but it was only $14, and i really dig it, and it works, and he had to walk back home to wherever he lives etc etc.
Then in the first 5 minutes of my first ride out, i almost got crunched between 2 cars. And i was informed before i arrived in China that if i wore a helmet here, everyone would think i was "special." But anyhow, so far so good. For all bikes and cars on the road, anything less than 98% attentiveness just isn't going to cut it around here.
