A lot of these small 16" wheeled bikes really have fantastic utility and add in the price, they punch high above what one might think of them; small wheeled; "small dahon copy"; etc

I have been considering using my son's bike for a light tour and been testing its riding and loadout and its so far been highly functional.
Bag with Drone
Bag with camera gear
1-2 days clothing, rain gear and tools
Tripod

Did a 60km the other day with my daughter and I really liked that it fell well into the type of cruising speed that most sight seeing touring will be with the ability to ramp up the speed a bit when needing to bridge boring parts of the route.
