Thank you for your observation.
I have asked our design team about this and they were able to inform me that if you want to keep the luggage mounted at the same time as completely folding up the bicycle, then just as you describe, the longer side of the hinge clamp lever conflicts slightly with the back of the luggage frame. To complete the final stage of the fold it is much more convenient to remove the luggage. .
Perhaps surprisingly, this point has been raised with us on only a few occasions.
Our design team feel that on the whole our bicycle users value being able to use the clamp as quickly and easily as possible above wanting to keep the luggage mounted through all the stages of the fold.
I do understand the desire to keep the luggage mounted to the frame, though. Some people are able to lift the folded bicycle with the luggage attached and this can leave them with a spare hand/arm which is useful when passing through station ticket-barriers, for example.
To achieve both requirements at the same time, it would appear necessary to either redesign the back of the luggage frame or shorten the longest side of the hinge clamp lever. The second of these options will reduce the ease of use of the hinge clamp lever, but perhaps could be done relatively easily as a modification if you wish.
Mounting the bracket further forward is unlikely to be a good idea because it would also require a different front carrier block, which will cause greater leverage, and less strength.
Our design team has been glad to receive this feedback and although we do not currently have plans to change this aspect of the design, the point has been noted and will doubtless be looked at again at alter date.
Thank you very much for taking the time and trouble to communicate your observation to us. I do hope you can enjoy continued use of you bicycle without much impediment by this aspect of luggage use.
