I am reposting this request from Will Reese on Facebook reposting Sam Balto on Beaumont-Wilshire Nextdoor.
If you have a bike you would like to donate, you can make a contactless drop-off at our house in close-in SE any time. Just message me. I have a bike rack and will deliver bikes to N. Portland.
