I've actually got one but not used it for months & having finally bought myself a Nipper Double I want to sell my Jane but can't for the life of me remember how to open it!!! I'm pretty sure the 2 grey rings either side lift but there's obviously something else as it still won't open....

Is there a locking catch half way down to release first, Google instructions for it and should come up with a mannual

Hi, i have one of these, on the left handside of handle bar there is like a tap shape that you
turn and at the same time slide the plastic on both sides up towards you and it should open. :)

Good luck
