The Ultimate Pulley Racer is designed after Doc Fizzix's own record setting mousetrap powered vehicle that traveled over 182 meters in 2003. The secret to this vehicles success is it's unique pulley system that is designed to maximize the transfer of potential energy over a 400% greater pulling distance than conventional propulsion systems. For ever turn of it's large drive gear the Ultimate Pulley Racer travels 10 meters of linear distance and has a total pulling distance potential of 200 meters. The Ultimate Pulley Racer comes ready-to-assemble with pre-cut and pre-drilled parts so you can be ready for action and racing on the same day. As with all our kits, The Ultimate Pulley Racer Kit comes with step-by-step instructions that are filled with tons of top secret performance tips and tricks that have been developed exclusively by Doc Fizzix so that you will have all the information you need to make The Ultimate Pulley Racer Kit a record setter. The Ultimate Pulley Racer takes more work to build than other mousetrap racer kits and is designed for those individuals who have had previous mousetrap vehicle building experience. The Ultimate Pulley Racer can be assembled in less than 120 minutes for most builders but setting-up and testing can take more than an hour.


  • High-tech pulley system
  • Reduced Friction Bearings
  • Adjustable Steering
  • Light-weight balsa wood
  • Brass tubing axles
  • Pre-cut and pre-drilled
  • Low inertia DVD layer wheels
  • Doc Fizzix's easy-wind, snag-free propulsion system
The high-tech pulley system replaces the conventional direct drive system with a combination of belt driven gears. A large light-weight plastic drive gear is attached to a smaller drive axle with a ultra thin cassette tape ribbon. The ratio of the drive gear to the drive axle is such that for every turn of the large drive gear the vehicle travels 10 meters linear distance. Because of the gear ratio of this vehicle, the Ultimate Pulley Racer requires almost 10 meters of cassette ribbon to be pulled from the drive axle through its 200 meter journey. This kit requires more work and testing than other kits so it should only be built by those that have experience building and testing mousetrap cars.
