Hi All,
Just a repeat of the other post:
Apologies for bringing back old threads, but you never know, it might help someone looking to do something similar.
As you will notice from the last post I had to unbolt the box every time I wanted to put my panniers back on, so I finally got round to making a bracket that I can remove when I want to put my panniers on:
It's made from steel bar and is lockable just as the pannier bracket.
It can be taken off so I can use it on a bigger box, etc.
Just right for all the odds and sods I need to carry, that don't fit under the seat.
