Description:If you are building a long-distance mousetrap powered or rubber band powered racer then one of the most basic design concepts to understand is gearing. Gearing in the simplest of terms is how far the vehicle will travel from the amount of string that is pulled from the drive axle. With mousetrap cars the gearing can be controlled by changing the length of the lever arm and/or changing the size of the drive axle/drive wheel system. Back by popular demand Doc Fizzix's Big Wheel is a guaranteed record setter that increases the gear ratio and the travel distance. The Ultimate Big Wheel is designed to cover almost 1 meter of linear distance for every wrap of string that is pulled from its drive axle. The Ultra-light Big Wheel is made from a very light weight corrugated plastic that can be cut and trimmed to save even more weight and even more rotational inertia translating into even greater travel distance. This is one of our best selling items, don't miss out. This is a 10-pack of 11-inch wheels, order as many sets as you need for your next large group activity.

Application:The Ultra-light Big wheel is used as the primary drive wheel on long-distance traveling vehicles. Designed to use a 3/16-inch axle, for every wrap of string that is pulled from it's drive axle the Ultra-light Big wheel will travel 1 full meter. The Ultra-light Big Wheel can be used with all mousetrap car and rubber band racer distance projects.
