Broken and unwanted bikes (Roche PL26)

Hi. I'm looking for broken and unwanted bikes that I can fix up to help us raise money for Cornwall Hospice care. Half of the money will go directly to the charity, the other half will go towards making our fundraising challenge this year possible as I'm not going to lie, I'm struggling after being ripped off by someone.

St austell/Bodmin area if possible please.
