Strong enough for MTB road bike, folding bike, kids bike, etc.
Very stable wall rack.
Design to be easily mounted on the wall for bike storage.
Material with high strength and hardness, high elastic limit, and fatigue limit.
What you need is a rack or stand that’ll hold your bike. If your walls are your own (or you have a tolerant landlord), then you have lots of choices in bike hangers that mount on the wall, ranging from simple hooks to nicely styled mouldings.
