North Plainfield police say 57-year-old Katie Miller was riding the bike through an International House of Pancakes parking lot in North Plainfield when she was hit Monday.
Restaurant manager Jose Preciado tells The Courier News of Bridgewater that he, a cook and several diners acted because Miller was having difficulty breathing and turning purple.
Police Chief William Parenti tells the newspaper the bystanders might have saved Miller's life. He says the 57-year-old woman suffered broken ribs and possibly a punctured lung.
Police say the pickup driver was turning and didn't see Miller until it was too late. He wasn't cited, but the accident remains under investigation.
