Slow Down Frozen Car

Hey Everyone!
I am rewiring a Frozen car to make the foot pedal into a push button for hand control. But for this child, the car goes a little too fast. What can I buy/do in order to slow down the car a little bit? Thanks so much!

Seen this done with a potentiometer (spelling?). The folks at Central Conn State University Go Baby Go just did this for Fisher Price Power Wheels Jeep during a recent build.

We usually add a motor controller. I have most frequently used a Riorand, but Nick has developed an excellent combination motor controller (reduces the speed of the car) that also provides gentle acceleration to the desired speed and gentle deceleration when the switch is released. It is adjustable and also programmable, and very well documented. You can contact him here:
Best regards, – Doug

Am active power stepdown is probably the best choice but i will note that if there two back motors for each back weel disconnecting one will result in a less powerfull slower car.
