Uni project research - home bike storage -please help! I gotta do it by Wednesday

hi everyone, i need your help!
i'm at nottingham trent uni currently doing research for a project. basically i have to write a report explaining why a new product needs to be designed, and ive chosen a bike rack to go in the home (student/city apartment with restricted space), so what i basically need to do is get everyone's opinions on what the advantages/disadvantages for the current designs on the market are, so here's a few of the best sellers.. any chance you could write what's good/bad about each one if you've used them..

i know a lot of designs are duplicated across companies, but i want to get an idea of what is good/bad about each design.

the sort of things i was thinking of were like some cause the pedals/tyres to touch the wall, damaging it etc.. or it protrudes too far into the room. that sort of thing..

so yeah, just write the number, then write something good or bad about the design, please :)

thanks in advance
