Biking The Ho Chi Minh Highway

Given that it is also comparably inexpensive, it really is a fantastic place everyone should try to visit sometime.
Downsides: Lots of people have figured out how awesome Vietnam is already, so you certainly won't be the only tourist.
Also, after you've spent five minutes on a Vietnamese street corner you'll appreciate that riding the Ho Chi Minh Highway is indeed quite dangerous... but just for reasons that have absolutely nothing to do with being a tourist.
I had to pay 150$ for a 1 month visa, so I don't know how they can encourage tourism with such high visa costs.

It's a shame the author skipped the Cham monuments in the middle of Vietnam. It's truly fascinating to see such robust physical evidence of ancient Hindu civilization amongst a modern, Sinitic one. This is part of the real beauty of Southeast Asia as a region. https://en.wikipedia.org/wiki/M%E1%BB%B9_S%C6%A1n
My family are actually about to spend a couple of weeks down in Yunnan's Wenshan prefecture on the Vietnamese border. It has great karst scenery, villages historically inaccessible except by boat through cave systems, cliff tombs, neolithic cave paintings, etc. That's just one corner of Yunnan (we also have Tibetan zones, tropical zones, etc.)
Another good option cycling out of Vietnam is northern Laos, toward Phongsali from Dienbienphu - really 'out there' villages, still real - and you can include your bike on boat trips down some of the rivers in the area.
Finally, if anyone's dead serious I am thinking of shipping two Weta trimarans - http://wetamarine.com/ - I sail on Fuxian Lake in Yunnan down to Halong Bay for a sailing/camping exploration of the archipelago before selling them. Been once before by public boat, there's some great beaches!
A similar highway exists in Thailand, the Mae Hong Son Loop[1], which I also did on motorcycle while I was backpacking Southeast Asia. Also highly recommended.

I would like to do something like this with a group of people.
Note I'm not particularly in shape, not "brave" by any traditional sense of the word, and hadn't ridden a bike in 15 years before my first bike ride, from Poland to Turkey (the above is my second). I have traveled quite a bit before then though.
I'd recommend knobby tires. There are a good number of other riders I met along the way, but only one was using a road bike.
Yup, I was alone.
I think a cyclocross bike with slick tires would be the best choice, assuming you want to do 100+ mile days. The 28mm tires were fine–the issue was fork clearance when they started to pick up dirt on the wet sections. If you wanted to ride on the dirt (mud) roads here you'd want at least 35mm.
The section I recommend (Day 5, Mile 70 to Day 10, Mile 64) is pretty light on traffic, especially trucks + buses.
