Looks decent enough to me. If the hubs are cheap open bearing (which I’m assuming they are) would recommend packing with a load of fresh/quality grease to begin with.
Depending on the fitness level of you GF you might want to consider the weight of the bike.
My GF is rather small and thus struggled to get on with heavier bikes, especially carrying luggage.
Any reasons why this wouldn’t be a good touring/bikepacking option for the other half?
