The Speed-Trap Racer is the fastest mousetrap powered racer anywhere and was designed after Doc Fizzix's own record-setting mousetrap racer that traveled 5 meters in 1.2 seconds. The Speed-Trap Racer is geared to generate a tremendous amount of torque while maximizing the transfer of potential energy into kinetic energy over a 5-meter distance. The Speed-Trap Racer is an easy-to-build top performing mousetrap racer that is designed for all high torque contests such as top-speed and King of the Hill. The Speed-Trap 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 Speed-Trap 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 Speed-Trap Racer Kit a winner.

Why Doc Fizzix:

At Doc Fizzix, we have been designing, making, and building mousetrap powered cars for more than 30 years. Unlike any other mousetrap vehicle kit you will find on the market today, each of our kits has been designed and tested over and over again to insure your success. We use only the best quality parts and components in our kits. We have been featured multiple times in books, magazines, and national aired programs. We wrote the very first book devoted exclusively to the building of mousetrap vehicle selling more than 200,000 copied world wide. Our kits are used in more schools across the country than any other brand. Mousetrap powered cars and vehicles is our specialty.


  • 6-inch high torque lever arm
  • 2-inch ultra sticky foam wheels
  • Light weight design
  • Brass tubing axles
  • Pre-cut and pre-drilled
  • Doc Fizzix's easy-wind, snag-free propulsion system


The biggest challenge with all high-speed racers is wheel traction. If wheels do not have enough traction at the start the racer will spin out wasting precious energy. The Speed-Trap Racer comes with two low inerita, ultra sticky, foam wheels that are made from a lightweight urethane that is designed to grab the floor and provide maximum traction and acceleration. While the rest of the field is spinning their wheels at the start line your Speed-Trap racer will be flying across the finish line in record time.

The Speed-Trap Racer Kit can be assembled in less than 45 minutes for most first time builders and when finished will travel 5 meters in 1.2 seconds. The Speed-Trap Racer Kit comes with a 6-inch lever arm making The Speed-Trap Racer Kit a super-fast dragster without the need for adjusting the lever arm length once assembled.

As with all our top mousetrap racer kits, The Speed-Trap Racer Kit includes our "easy-to-wind" and "snag-free " string release system that will not tangle or snag for increased performance, a technique developed exclusively by Doc Fizzix.
