I have been a fan of charity shop giving (in particular Oxfam) for many years. However they understandably can’t take many items. So what do you do?
You join the Freecycle Network which currently consists of 4,134 groups with 3,927,000 members across the globe. It is a grassroots and entirely non-profit movement of people who are giving (& getting) stuff for free in their own towns. Due to the local nature of the exchange it also helps reduce your carbon footprint.
Each local group is moderated by a local volunteer to keep out spammers, and I have found a group for my local town. In the last two years I have ‘Freecycled’ three bicycles, two dead computer printers and a sofa-bed. Plus I acquired two boxes of unwanted candles.
If you want your bicycles to go to a really good home I suggest using Re-cycle.
