Old bike donation

Hi all, looking to get rid of an old bike or two and was hoping to donate to some kind of cycling organisation/charity that specialises in this sort of thing, either to give to somebody to get to work or for youth maintenance training or something along those lines. Both bikes are roadworthy but were used as winter commute ‘disposables’ meaning they’re roadworthy but didn’t receive much in the way of TLC, and definitely require some maintenance and new parts.

I don’t want to just leave them unlocked outside as they’d probably end up in the Thames.

Anyone know any organisations like this in central/south/southeast London, especially ones that would come around to collect?
