My Copper Grit Scooter

Coated in purple and black
Goes up the tallest ramps while eating speed.
Grinding and screeching against the strongest metals
Whilst going higher than the clouds.
Floating, whipping and spinning over the ramps then
Crashing and bashing on the concrete.
I fear busting an old rusty wheel will be expensive,
But I keep pushing, pulling, kicking, ripping bars.
Under the balcony it rests,
But rusts away in the rain--
Grain by grain--
Fading away, weaker and weaker it gets,
Slower and slower, it shall be ruined,
But it is still my scooter.
