With the release of Dr. Stone: Science Future part 2 episode 3, the anime saw Senku and the Kingdom of Science outsmart the American team by using a decoy. The anime later saw Kingdom of Science deploy their bikes to travel across South America, leaving Stanley and others stranded.
The anime's previous episode saw Senku and others find Dr. Chelsea during one of their stops to stockpile some fuel. Dr. Chelsea, a geographer, joined Senku's team to help them reach their destination. While Stanley Snyder did inch closer to the Kingdom of Science's boat, they managed to get away.
Dr. Stone: Science Future part 2 episode 3 - The Kingdom of Science creates bikes

Dr. Stone: Science Future part 2 episode 3, titled The Escape, opened with Dr. Chelsea suggesting to Senku and others about possibly going to their destination through the Panama Canal. However, considering it had been thousands of years since humanity had maintained it, there was a good chance that the canal had gotten covered up.
That's when Ukyo came up with the plan to use the American team's radar operator's skill against them. In the hope of getting Stanley Snyder away from them, Senku and others deployed their lab car unmanned toward the Panama Canal. This development forced Stanley to chase after the lab car as if it weren't a decoy; the American team would lose track of the Kingdom of Science.

In the meantime, the Kingdom of Science set off to a nearby land to cultivate sap from rubber trees. Soon after they acquired the sap, they produced rubber and set forth again for South America. During this journey, Taiju was tasked with the heavy-duty work of turning the rubber into sheets, which Senku later turned into tires.
Soon after the Kingdom of Science entered South America, they began ripping apart their boat to use the materials to make bikes. Senku planned on making six bikes: one boss bike and five mini bikes. The boss bike would be tasked with turning wood into fuel for the other five bikes.

Elsewhere, after Stanley Snyder realized that the lab car headed to the Panama Canal was a decoy, he headed to Ecuador, where Senku and others were. However, the moment they were about to make landfall, the Kingdom of Science deployed its newly created bikes and began travelling across South America.
In response, the American team attacked the Kingdom of Science with their guns. However, the Science team managed to evade them. Amidst this, the American team also deployed its aircraft. Unbeknownst to them, Senku had already tampered with it. Hence, the aircraft came crashing down. While Senku and others indeed escaped, Dr. Xeno managed to give Stanley a message through Morse code.
