Hmmm... half the bodyweight, eh? How about 3/4?
I weigh 240 lbs. and this is my preferred way to travel:
22 bike
30 Trek Mt. Train single-wheeled pedal trailer for son
55 six year old son
30 Bell two-wheeled trailer for daughter
44 five year old daughter
5 picnic supplies, toys and water.
186 lbs. or 77.5% of my body weight. 89% if I take the 22 mos. old also.
Granted, we never go more than 25 miles this way, make frequent unscheduled stops to chase butterflies, look at interesting bugs, collect leaves and generally explore stuff, and, yes, we do slow down a lot going up hills (but I still never get to my lowest gear, undoubtedly because I have such a fine stoker behind me), but I can't think of a finer way to travel. They ain't heavy. They're my kids.
