We source the majority, if not all of our bikes from thrift stores. We typically don’t accept solicitations on bikes for sale. If we purchase bikes private party, we typically seek out the bikes on our own.
We run all serial #’s through a city/police database known as RAPID (Northwest Regional Automated Property Information Database).
This is because we have a Secondhand Dealers permit. From the City of Portland website: "Shops that buy and sell used or new property that is frequently the subject of theft ("regulated property") must have a permit. Acquisitions of regulated property must be reported to the Police Bureau and the items must be held for a set period of time before it is made available for sale."
