[Closed] Donating old bikes...?

Anybody know of any schemes or places in the London or Essex region where you can donate old complete bikes or big parts e.g. Frames, Wheels?

I have an old Ridgeback Cyclone converted to singlespeed that is taking up room and I would rather pass on to a worthy cause than get £12.50 on the eBay... it's actually not in too bad nick and motors along nicely on it's rigid front forks.

Was my old commuter bike but I actually XC raced it once - never twice! And did last years London to Southend ride on it.

Help me find a good home:-)
