What's this speeding along a track? Is it a plane? A rocket? A bullet? It's really a bicycle shaped like a bullet! These models are often made by enthusiasts for record-breaking speed attempts. This one was made by Canadian triathlete Greg Kolodziejzyk because he wanted to break the record for a human-powered vehicle (HPV). And he did break the 24-hour distance record! His bike had food, water and waste bags. At 70-pounds, it is capable of hitting 60 mph on a flat road.
