indoor bike rack

problem:  -bikes take up needed space inside of a small flat.
               -some bikes are bulky, or heavy.
             
solutions:- not ride a bike.(skate, unicycle, scooter)
              - lock it to a pole in front of your home.

              -use suction cups attached to hooks to hold the bike up on a wall without damaging the wall.

         -you could put two shower poles on your ceiling, then hang a hammock or strings with hooks in strategic places to hold up a bike.

                                                        DECISION MATRIX
 

the most easy solution would be to have a bike lock or a chain with a pad lock, but because that's too simple I'm making a CAD model of my 'bike hammock' or just strings suspended with hooks attached.

looks pretty good lets see how it does in the four quadrant feedback table->

not too shaby.
