My bike plus gear is way more than half my bodyweight. I'm 5'2" and 11x pounds where 1 < x < 6

bike: ~34
gear: 30-50
depending on season (clothes),
distance to next services (food/water),
temperature (water),
geographic region (haven't really tested this yet, but i would be carrying more spares for a remote trip),
length of trip (slight variation in spare parts),
which bags I choose to carry - my arkel bags are huge but very heavy, my others (lone peak + canondale) are lighter & smaller
