You have 2 options:
1. Buy a Zip zap and then take off the body of the car and remove the front steering knuckes and front wheels, and swap the with the steering knuckes and front wheels on your Bit. You can remove the knuckles by either lifting them up and pulling them out, or by unscrewing the cover on the front of the car and then taking them out.

2. Buy the ZipZap gear kit, and the ZipZap Rim and Tire kit. Take two of the rear rims from this kit and separate the rims from the gear and the axle. Now take the 2 rims that were up against the gear (these rims will not have the nub on the inside) and drill a tiny hole from the rear to the front throught the center of the rim. Now take the steering knuckles from your Bit and using a small knife or screwdriver, pop the pin out that holds in the wheel. Now put those pins through the rims you just drilled holes in and the put them back into the steering knuckles. Now put on some of the ZipZap rims and tires on that wheel and you are set.

Hope that helps.
