If you have a source for any of the parts required please share it in this thread and I will add it in to the parts-list under the resources menu. Likewise if you want to share your experience with suppliers listed.
The goal with this is to document where people can find local suppliers to buy the parts needed to build a cyclekart. It will also act as a point of reference to assist with peoples designs and help them to choose suitable suppliers
Online sources that post to Australia are also welcome as they often provide cost effective alternatives.
