I think the top comment up the chain has already mentioned one approach, which is "chop up stolen bikes". There are plenty of other options, but that one would be a solid start. Given the typical price of the kind of bikes that get stolen and chopped, that's a pretty solid income for drugs.
Seattle's local news station had an interesting coverage last year on the topic of stolen bikes specifically[0]. Take a look at the following quote:
> “So we have 1, 2, 3, 4, 5, 6, 7, 8 bikes all reported stolen in the Seattle area,” says Hance. “Not all of them have prices. This one does. It’s $5,000 bucks. This one’s $1,500. This one’s $5,000. This one’s $900.”
Obviously the stolen ones will be selling for cheaper than the prices you see above. But even if we say that the stolen price is only 25% of the real cost (totally guessing, as i have no idea for the price conversion of stolen to clean), that's still quite plenty for drug money.
