Two Wheels Good

"What I always say is two wheels are best!"

- Mr. Percival

Two Wheels Good is the fourteenth episode of the nineteenth series.

Plot
Lord Callan is having a special birthday ball, and Spencer has to take the Duke and Duchess to Callan Castle. The Duke has prepared a speech, as well as bringing a present. He reminds Spencer that they must get to the castle on time, and Spencer promises that he will not let them down.

Spencer's first stop is at Knapford, where the Thin Controller has just arrived on his bicycle to have a meeting with the Fat Controller. The Thin Controller tells him that he prefers to ride his bike, as "two wheels are best." Bertie disagrees and thinks that four wheels are best, while Thomas likes his six wheels. Spencer arrives and boasts that twenty wheels are the very best. The Duke reminds Spencer of his job, so Spencer sets off again.

Spencer speeds along confidently, when suddenly, his valve gear snaps and he slows to a stop, unable to go on. The Duke begins to worry about being late when Thomas arrives. He teases Spencer about his twenty wheels letting him down, and offers to take the Duke and Duchess the rest of the way to the castle, to which they agree.

But Thomas has not gone very far before he has to stop to avoid hitting a fallen tree. Bertie pulls up, and offers to take the Duke and Duchess himself. As they climb aboard, Bertie boasts that four wheels are best. Bertie hurries towards the castle through the quiet country roads. But suddenly, he runs over some nails laying in the road, and punctures a tyre. The Duke is just about to give up hope when the Thin Controller arrives on his bicycle. The Duke tells him about his important destination, so the Thin Controller sets off to the nearest phone box to call for help. Soon, Harold arrives to pick up the Duke and Duchess. They quickly climb aboard and Harold flies them to the castle. Lord Callan greets them and asks where Spencer is. The Duke promises to tell him over dinner, and thanks Harold for his help.

That evening at Knapford, Spencer feels very embarrassed for breaking down. But his valve gear has been fixed, and Bertie's flat tyre is mended too. Thomas still does not know how many wheels are the best, while the Fat Controller tries to ride the Thin Controller's bike, but he does not get the hang of it. Harold flies over the station, and Thomas realises that he did not even use his wheels.

Trivia

 * Going by production order, this is the sixteenth episode of the nineteenth series.
 * This episode marks the first of a few things for Lord Callan:
 * His first appearance since The Great Discovery.
 * His first appearance in an episode since the eleventh series episode, Dirty Work
 * His first speaking role since his debut in the seventh series.
 * His first appearance in CGI.
 * The plot is similar to the fifth series episode, Lady Hatt's Birthday Party where the Fat Controller uses his car, Caroline, George, and Thomas, as for the Duke and Duchess they use Spencer, Thomas, Bertie, and Harold.
 * Instrumental snippets from the special The Adventure Begins can be heard throughout the episode.
 * The scene of Harold arriving at Callan Castle closely resembles the scene where he rescued the climbers from The Thomas Way so it could possibly be stock footage.
 * At the end of the episode, Thomas was laughing in the US dub, but Thomas was not laughing at the end of the episode in the UK dub.
 * The episode's title is a reference to the famous quote "Four legs good, two legs bad" from George Orwell's novel "Animal Farm."
 * This was the very last episode that aired on PBS Kids in the US on 31 December 2017, when Thomas & Friends was removed from their lineup and moved to Nick Jr. the following March.
 * In the Estonian, Latvian, Lithuanian, Baltic Russian and Vietnamese dubs, the UK dub can be heard in the background as a dubbing track was not used.

Goofs

 * When Mr. Percival uses the telephone, he faces away from the phone itself with the earpiece to his ear, but does not speak into the mouthpiece built into the box. The person receiving the call would not have been able to hear him properly.
