Huh? Serious ah? I haven't seen people hanging motorbikes on walls at home. How do it even go in the lift? Unless of course if you live in a landed property. Then again, your wall will crash... Or do you mean eBikes?
I've seen those things on TV, you'll have to get it online and ship from the US. I am pretty sure that it will constitue some sort of rule breaking if you ever used it on the roads here without LTA approval, but go for it, you'll get on Stomp at least, .
