The mystery

It was a cold misty morning, I was jogging my 10 kilometres when I came to a halt as I saw a large neon green bike, pedalling itself whilst being zip tied to an electric pole. I went back to walking when I heard a large thud behind me. It was the bike. It broke the zip-tie and started chasing me .Others bikes came and joined the green bike.They were 10 feet apart from me. I was now desperate to get away from the bikes. I looked back and I wished I never did. I was trampled on.
