No idea. The reason they withdrew the service in the first place was Covid-19, or so they say. Quite how bikes that would be subject to the same security checks as normal luggage would present a security issue is anyone's guess. And customs issues sounds like horseshit, unless they reckon people are going to flock to France to buy bikes and 'import' them back. And I can't see that being remotely worth it.
How is that related to bicycles in any way??
