mousetrap cars and vehicles

Automatic and adjustable brakes
The Incredible Braking Car is one of the coolest mousetrap powered racers you will ever see. The Incredible Braking Car is a super fast racer designed to come to an instant stop by using its onboard automatic braking system that is consistently accurate to within 2 cm of just about any distance. The braking system is so easy to operate you can adjust it for almost any distance in seconds. The braking system will work consistently for any distance within 1-10 meters.




Great for "king of the hill" challenges
The Incredible Braking Car is also engineered to generate a tremendous amount of torque while maximizing the transfer of potential energy into the kinetic energy.  Because of the high amount of torque that is produced by The Incredible Braking Car it makes a great “king of the hill” climber or speed-trap dragster.
