For ESL learners
on your bike means: Go away.. Register: very informal, slang. Suitable only for casual conversation, chat and social media. Do not use in business, academic or news writing. A common learner mistake is using the word in a register it does not fit, or assuming a single global meaning; native speakers immediately notice when slang appears in formal contexts, so always check the surrounding register before producing it yourself.

For specific readers
Why is this section here?
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.

- on yer bike83%
A British idiom meaning 'get lost', 'scram', or 'you're not welcome here' — said with varying degrees of heat depending on the situation. It can be a jokey way to tell someone to stop bothering you or a genuinely hostile dismissal. The phrase got an extra layer of meaning in 1981 when politician Norman Tebbit referenced his unemployed father 'getting on his bike' to look for work, turning it into a loaded piece of British political shorthand about self-reliance.
