    • ask someone for help to put the chain back on.
    • identify and name key bicycle parts like chainring and cog in French.

    Words you’ll actually use

    Listen once. Try it slowly. Then say it without looking.

    Checking available voices…

    Ma chaîne a déraillé.

    My chain has come off.

    ma shɛn a deʁaje

    The most common way to say the chain has derailed or slipped off. Use in informal or neutral contexts.

    La chaîne est tombée.

    The chain has fallen off.

    la shɛn ɛ tɔ̃be

    A simpler, equally natural alternative. Often used when the chain is completely off the gears.

    Pouvez-vous m'aider à remettre la chaîne ?

    Can you help me put the chain back on?

    puve vu mɛde a ʁəmɛtʁ la shɛn

    Polite request for help. Use 'Pouvez-vous' with strangers or in shops; with friends, 'Peux-tu m'aider à remettre la chaîne ?' is fine.

    Je n'ai pas d'outils.

    I don't have any tools.

    ʒə ne pa d‿uti

    Explain why you need help. Useful when you lack a chain tool or Allen key.

    Est-ce que vous pouvez regarder ?

    Can you take a look?

    ɛs kə vu puve ʁəɡaʁde

    A general request for someone to inspect the problem. Works in bike shops or with a helpful passerby.

    Pronunciation guides are approximate. Slow playback keeps the original pitch.

    Make it make sense

    Useful pattern

    To describe a mechanical issue, use 'avoir' + past participle: 'Ma chaîne a déraillé' (My chain has derailed). This pattern works for many bike problems: 'Mon pneu a crevé' (My tire has punctured), 'Mes freins ont lâché' (My brakes have failed). For a more literal 'fallen off', use 'être' + past participle: 'La chaîne est tombée.' Both are correct; 'déraillé' is more specific to derailing, while 'tombée' emphasizes the fall. Note that 'dérailler' is intransitive and takes 'avoir' in the passé composé, while 'tomber' is one of the verbs that takes 'être' and agrees with the subject.

    When to use it

    Use 'Ma chaîne a déraillé' when you want to be precise about the chain coming off the chainring or cassette. Use 'La chaîne est tombée' if the chain is completely off and lying on the ground. When asking for help, 'Pouvez-vous m'aider à remettre la chaîne ?' is polite and clear. In a bike shop, you might say 'Bonjour, ma chaîne a déraillé. Est-ce que vous pouvez m'aider ?' In informal settings with friends, switch to 'tu': 'Peux-tu m'aider à remettre la chaîne ?'

    A conversation you could have

    Listen to each line, then take one part and reply out loud.

    A

    Excusez-moi, ma chaîne a déraillé. Pouvez-vous m'aider à la remettre ?

    Excuse me, my chain has come off. Can you help me put it back on?ɛkskyze mwa, ma shɛn a deʁaje. puve vu mɛde a la ʁəmɛtʁ
    B

    Bien sûr. Vous avez un outil ?

    Of course. Do you have a tool?bjɛ̃ syʁ. vu zave œ̃ nuti
    A

    Non, je n'ai pas d'outils. Je ne sais pas comment faire.

    No, I don't have any tools. I don't know how to do it.nɔ̃, ʒə ne pa d‿uti. ʒə nə se pa kɔmɑ̃ fɛʁ
    B

    Pas de problème. Je vais vous montrer. Il faut la remettre sur le plateau.

    No problem. I'll show you. You need to put it back on the chainring.pa də pʁɔblɛm. ʒə vɛ vu mɔ̃tʁe. il fo la ʁəmɛtʁ syʁ lə plato

    A little context goes a long way

    In France, cycling is popular, and many people are familiar with basic bike repairs. However, don't assume everyone knows how to fix a chain. In bike shops, staff are usually helpful, but it's polite to greet them first with 'Bonjour' before asking for assistance. In informal settings, using 'tu' is common among peers, but with strangers or in professional contexts, stick to 'vous'. Regional differences: In Quebec, you might hear 'ma chaîne a décroché' or 'la chaîne est sortie', but 'déraillé' is also understood.

    One thing to watch for

    Saying 'Ma chaîne est déraillée' (using être instead of avoir).

    Try this instead: The correct form is 'Ma chaîne a déraillé' because 'dérailler' uses avoir in the passé composé. 'Est déraillée' would be passive voice, implying the chain was derailed by someone, which is not what you mean. Stick with 'a déraillé' for the active meaning. Note that 'dérailler' is intransitive and takes 'avoir' in the passé composé, while 'tomber' is one of the verbs that takes 'être' and agrees with the subject.

Remember to greet with 'Bonjour' and use 'vous' with strangers. Knowing the words 'plateau' (chainring) and 'pignon' (cog) helps you explain the problem clearly.
