It is just the shifter switch. Just to check you can exchange the red and blue wires under the pedal(just for a second or so, do not do this permanently) to see if you get power to the wheels, if so then yes it is Definitely only the shifter, but I am sure it is just the shifter. you can also call Peg Perego Tech support which is excellent and they can help you too 1800-728-2108 and parts can be priced and found at www.mypegperegoparts.com
