in our garage we have 7 bikes... well, honestly there are 9 -but we're selling 2 of them this week
2 roadbikes < 20lbs
1 29er MTB < 25lbs
and 4 26" heavy steel bikes > 30lbs
the kids bikes are the heavier ones (how does that happen anyways!?!)
The kids aren't "little" per se; our youngest is 11...
I love the though of the hoist setups but I'd be afraid of the kids yanking the bikes up/down all the time. A floor based rack is easy - but takes up a lot of space.
4 of the bikes are continually on the move for work/school, etc and the others don't get much ride time - but are around nonetheless...
