I have a couple of bikes that I only ride once in a while . If someone is visiting or needs a bike ride and doesn’t have a bike , they are handy. I hired a homeless guy to do some work at my shop and he had just had his bike stolen. I had a mountain bike I hardly ever used and gave it to him. He completely destroyed the bike in about two days so I decided any other donations would go to our Hub , a local co-op. They so appreciate anything they get, even an unwanted frame. They have so many parts( at least three or four boxes from me) , a frame becomes a complete bike and gets sold on. It is rewarding to support them , they teach folks how to work on bikes and charge very little for it. Another vote for donate!
