Yep, I like Caretaker's last point too.
I sometimes think the bicycling is part of the tour as well but with different people how that bicycling is done can be a curiosity. If I see someone with no legs riding a bike you can be sure I'm looking twice or asking a question or two about how that all works. I looked at a downhill mtb for a double amputee on the Varna website and my son and I even had a discussion about what perceived needs would need to be addressed (he downhills). Likewise, when I hear about a guy losing 1/3 of his heart muscle but still trying to ride with his friends, I'm curious how he achieves that. If the answer is e assist adapted to his bicycle I don't get worked up about it.
Now we have a guy who has diabetes and could not tour if not for e assist. How does he do it? To argue about his bike misses the human story or even how he cycles. The nit picking misses the wider, more interesting story.
