Excellent work, bike looks great. Before you shorten the cables make sure you are happy that the bike will still fold. Cables on some folding bikes have to be longer to give some slack when folding the bike.
Have you considered some quick release pedals such as Wellgo QRD or MKS EZY? That would make packing into the case a bit quicker.
Thanks for the pointers to those pedals. I will look into it. The bike came with unbranded plastic folding pedals, but they're not currently mounted since I won't be doing a suitcase fold for another two months or so. The bike folds fine with the derailleur cable length so I ASSUMED it would be Ok To shorten the other cables to that length; but thanks for making me re - think that before I cut cables.
