I had a friend whose father was really into motorcycles and he LOVED CHiPs. So when his boy wanted a toy to ride around you better believe it was going to be based on CHiPS. I remember him definitely having that big wheel one because of the siren (which we all wanted so badly), but I think he also got the larger one. It was an awkward one to get because by the time he got it, he already wanted a regular bike. If he still owned it, the thing would probably be in mint condition.
