Broken and unwanted bikes (Roche PL26)

Hi. If you have a bike sat broken or unwanted it could really help me. This year I dreamed of doing a charity challenge to help me through my depression. A banger rally challenge to Benidorm. I need to raise £1500 and I've been fixing up bikes to try and raise that money.

We're going to use it to fundraise for Cornwall Hospice Care who looked after a family member as well.

If anyone has anything that could help it would be hugely appreciated. Thank you.
