Monster Wheelie

Monster Wheelie, a rubber-band driven drag car for children

• This car is designed to allow children to have the appeal and fun of stylish Matchbox cars with the real world ability to use a self propelled vehicle that can pull wheelies!! The tension provided by the elastic band will produce a torque on the rear axle, which will be converted to the large rear wheel, and therefore, utilizing a large friction coefficient, to the ground. The moment created by this torque will lift the front wheels off the ground and a wheelie bar will keep the vehicle from flipping backwards.
• There will also be an open cockpit to allow the user to place any small toy action figure into the Monster Wheelie!!!
• The vehicle will be approximately 8 to 12 inches long. This will be very open and can be changed.
• The design of this toy focuses on the ability of elastic potential energy to be converted into mechanical energy, in this case torque on an axle. Other principles include friction and the use of counter weight (making pulling a wheelie require less torque- located on the wheelie bar most likely).
• This toy will be made of light-weight aluminum, or some form of light wood such as balsa wood in a solid frame to allow the car to maintain a light weight, but also durable structure. Therefore, production costs would be somewhat high, probably in the $6 to $9 range, meaning the retail cost could also be reasonable, somewhere in the range of $25 to $30. This cost may need to increase since the toy's structure is to be sturdy, meaning it will probably not need to be replaced or repaired
• There will also be a market for aftermarket parts that will help further modify and customize this toy
• The toy could also be manufactured with an electric motor to be self-propelled and possibly even remote-controlled
• Monster Wheelie would be recommended for age groups above 7, but because of the internal, protected elastic power source, the toy will be safe even for children of younger ages
• Different sizes of the vehicle with different power sources (ribbon spring, electric motor) could also be manufactured to allow for different age groups, interests, etc.
• The vehicle could also model real life vehicles such as formula cars, Chevrolet Corvettes, Camaros, and even monster trucks
