A bit of interesting history.
SAE was really into '2-wheelers' when I took over as SAE's head Buggy Nerd in the early '70's.
We kicked ass, uphill. One of our 'un-faired' 2-wheelers' was named 'Arnold' - after Arnold Schwinn.
I was buggy chairman at SAE for several years when SAE was still using 2 wheelers; SAE was then 'into' bikes (2 wheelers) for many years, and was very competitive - Top 6 for many years.
The key was that they were super light (compared to 4 wheel buggies), and we could beat anyone up Hill 1 - thence the problemo begins.....
Here's the rub:
Our 2 wheelers where killers on hill 1 and 2. But then the buggies had to pass them during the free roll - the free roll speed of 2- wheelers was so-so, and the buggies had to pass them somewhere during the free roll.............
The bike driver could see what was happening, but the buggy driver(s) could not - hence possible danger. Hence, much griping by the '4-wheel buggy' teams.
Our 2-wheelers would corner well (in The Chute) and roll OK, but were a bitch to get started (Hill 1) and push off (Hill 2), without torquing them and causing an instant 'dump'.
So......we beat them all up Hill 1 and then played 'catch up' on Hills 3 + 4 + 5. Still, we got into the top 6, often
Bottom line is that 2-wheelers were deemed 'unsafe' (BS) - and - to be fair - and some 2- wheelers were very unstable when pushed - so SAE (during my generation in the early '70's) - slowly converted to 'real' buggies.
SAE's 2 wheelers were great in The Chute, but never got really hauling (reached terminal velocity right away just prior to The Chute) ) - forcing the 'real buggies' to pass them during a difficult moment.
A bit of history.
A guess - I'll bet that the ultimate ultimate buggy would be a 2-wheeler, especially is it had some sort of 'active' nerdoid stability control.
