I agree with your point that the OP is unlikely to get a Pinion bike first off. They are available from Co-Motion, they are out on the west coast US somewhere. Expensive bikes. I followed Darren Alf, the so-called “Bicycle Touring Pro”, on his travels thru much of Europe on how Pinion equipped bike. He had nothing but good things to say about the system, but a noted they are very expensive,
