i got the heaviest one up rack
think it will do 75lbs for each bike holder, when i was researching a while back it seems that was the heaviest weight of all of them
on the others felt the bikes, bike bags etc were putting me closer to the weight limits than i wanted to be
like that new thule electric bike rack with the ramp, that wasnt out when i was looking
but it is still lower weight rated than my one up
but i think the thule is lighter and it folds up nice
just checked and the one up is up to 75lbs each bike on the heavy duty one
plus you can add 2 more to it with the extension and go up to 200lbs total
