Big Chris is Silver Hatch race track's mechanic. He occasionally commentates, and starts races. He lives in Rusty the caravan, and looks after the race track and cars. Big Chris has a typically northern catchphrase, "You bend it, you mend it." Big Chris is portrayed as being very messy and absent-minded, often "losing" objects directly in his line of sight, and eternally surprised by his own walkie-talkie. While working on the cars, he often practices his karaoke with an out-of-tune version of a song called "Motor Man". He is voiced by comedian Peter Kay.
