The problem with multi-rider cargo vehicle is the space and time the extra
rider(s) would cost, unless the cargo is heavier than one rider can handle.
Electric motor assist is gaining popularity here.
Couple of weeks ago, I got leg cramp going up a train overpass, after ~3 hrs
riding the futon trike, ~200 lbs with cargo to and back from work. I
was surprised that I could limp my way up hill, while loosened up the legs for
another go back home. The next overpass, I had no hesitation getting off the
trike and pulling it up hill (no ego damage). It seems that pedaling cargo
uphill costs a lot more energy than pulling.
So do we have a new requirement for python walk-ability, with full load going
uphill?
