There is an Item on Henry Cutlers Site Bakfiets - en meer.nl Henrys Workcycles about the Long John and how really useful they are.
He was introduced to them soon after his Arrival in theNetherlands in 2000 which inspired him to open His Bicycle Business Selling his Excellent Bakfiets and City Bikes.
I mentioned that there is one in Dublin and here it is on South King Street beside Saint Stephens Green.
I have noticed on my way Home from the City this Long John Ambling along the Cycle Path into Town on the Nth Strand Road and tried to Photograph it but it was on the far side of the Road so I did not bother to try and chase it. So I eventually Photographed it on South King Street. It looks like they Cobbled it together from Bits and Pieces.
