Bike recycling centre Walthamstow

There is this one too http://www.bikeworks.org.uk/contact-us-map.php in Bow. They are a very helpful not for profit organisation.

Bikeworks has always got lots of old hack bikes, they often build them up as single speeds and sell them on very, very cheap.

Object email Jim there he may well take them off your hands.

15 minutes after I emailed I got a phone call. Looks liek you've just helped me rescue some bikes.
