About halfway through the episode, when Jon and Ponch lose the car thieves and are being watched by the detectives on the hill, they stop. When they continue down the dirt road, you can tell that they're on the bike trailer, because you can hear the trailer squeaking, and they begin moving before they start the engines.
From CHiPs Online: Whenever Ponch and Jon drive down the hill while chasing the stolen cars (first in Jon's truck and then hours later on motorcycles) it's foggy...even though the skies are clear everywhere else. It was even clear when they were skydiving. Just after Jon stops his truck because of the "accident" on the road, we see Bonnie walking along taking a measurement of skid marks. Why? Did someone die? Accident reconstruction teams aren't supposed to be called in unless someone died. How could someone have died when the worst that happened was the truck slowly tipped over? And we know the drivers are OK since Ponch says, "Luckily no one was badly hurt." Before Ponch knows who the ice cream is from, he's about to eat it. Isn't that dangerous? What if someone had something against the CHP and wanted to hurt an officer?
Jon: (to the "Supercops") Sergeant promised us an ice cream cone if we came out here and ride fast, flash our lights, toot our sirens and chew gum at the same time.
