Crank Spin

Popped right out of the sneaker and bolted straight out to the sunny driveway! A mountain bike was leaning against the brick siding on its kickstand, rear wheel lifted just off the concrete. Pure potential energy right there. I grabbed the serrated edge of the low pedal, hoisted myself up, and stomped down with all my weight. The crank arm rotated with a sharp metallic clatter, whipping the oily chain across the gear teeth! That massive knobby tire spun into a roaring blur of silver spokes and whirring hub clicks. The whole frame hummed under my boots—felt just like revving a rocket engine!
