No official statement, that we can find as yet from Babboe. But NL Times have reported:

The company set up a website where customers with a Babboe CITY or MINI cargo bike can enter their frame number to check whether their bike falls under the recall.

Your frame number should be on the Seat Tube as pictured below:

We have entered some of our frame numbers on this Dutch language site, the website has taken our contact details and said that they will get back to us.

Please use this site to register your frame number. We will be trying all of our models in stock to see whether is limited to the City and Mini models. We still need clarity on this direct from Babboe.
