I seen where people have a metal frame thing fixed to wall and they can hang bikes up there. I got my guitar hanging from wall but my bedroom walls are plasterboard and I've heard of stories of people's tv's falling off the walls. but if you use plasterboard fixings it should be ok yeah. I keep visualising a bike hanging above my bed head, I think it would look cool, u see I'm hoping to get hybrid bike which are a little lighter in weight and it would be a plan to hang it on wall when not in use. what do you think? I've not had any shelfs with dvds and statues or mirror or guitar or dart board fall off the wall yet lol
