Ashbro, oh the irony!
So, I just got a call from TfL, they told me that the on-street team doesn’t have a target for collecting damaged bikes, in the same way that they have targets for redistribution.
He said they only pick up damaged bikes when a ‘certain number’ of red-lights have appeared on that docking station (he wouldn’t tell me what the magic number was). So, damaged bikes could be sitting there for days if no other bikes are reported as broken in the same docking station.
He did refer to ‘enough to fill a van,’ though. So I wonder if he means they wait until there are enough red lights in a particular neighbourhood (now that docking stations are classified by neighbourhood) to justify sending a van out.
