Amorphous, highly elastic materials (glass comes to mind) are often not great for long-wearing designs like bicycles. At least to present, amorphous metals wear more like glass or carbon fibre than steel: invisible structural damage leads to quick catastrophic failure. Rather than dings you get severed seat tubes and exploding wheels. For the time being, no one's invented anything better than cro-moly steel for the good old bicycle. It does sound like an utterly fascinating material, however. The slow, glass-like viscosity curve would be an amazing property to play with.
