G'Day,

The infamous Jiaoji Road bike market had a few shops selling them outside on the main road (Jiaoji Road towards the end, past the actual market, past Red Egg Man / Ms.+Mr.Muffler):

Checked websites like Taobao / Alibaba / Made-In-China yet for the mini pit bikes (bought some to trash around for approx. 400RMB per bike last year, they lasted one afternoon and some beers). Quite a few manufacturers are located in the Yongkang area.
