A bit space consuming. During the indigogo campaign they optionally offered a socalled "one cable solution" that did not need/use the connector. I'd consider this a good solution for the Brompton. It seems that only a handful of people ordered that, possibly beccuase they were not aware of the space issues on the Brompton. What makes it even more interesting is that the weight of the battery is on the frame, not on the handlebars. A bit more sophisticated is the solution on the nano Brompton kit where the battery is also in the brompton bag, but the connection is done via the luggage block, so no need do connect or disconnect cables.
