Judy Dunne, who weighed between 450 and 500 lbs., received an exercise bike from her children as a birthday present. The bike was purchased from Wal-Mart Stores Inc. She rode the bike for a moment, peddling three or four rotations. The bike collapsed and Judy sustained serious injuries. The bike was designed for use by people up to 250lbs(which is 99% of the population), but the manufacturer did not specify a weight limit in marketing the bike. Is the bike defective? Can Dunne recover for product liability from the manufacturer and/or Wal-Mart? Explain.
