    I am very interested in your back wheel kit however my bike is thru axle. Have you got plans to develop your kit for thru axle and if so when is this likely to BA available? I see Boost have already released theirs but I would rather purchase a Geeko kit if possible

      Hello, thank you for your attention and have a nice day!
      We are planning to develop through-axis motors. But as you know, it is not easy. There are many sizes of axles, so adaptability is very important. We will let you know if there is any progress, thank you!

      je suis aussi très intéressée par le kit arrière à axe traversant.

        Bonjour, merci de votre attention et bonne journée !
        Nous envisageons de développer des moteurs à axe traversant. Mais comme vous le savez, ce n’est pas facile. Il y a plusieurs tailles d’axes, donc l’adaptabilité est très importante. Nous vous tiendrons au courant des avancées, merci !

  9. jose Menes says:

    les vélos avec des freins à patins conviennent-ils pour ce type de kit?

    1. Gina says:

      Bonjour, merci pour votre demande et bonne journée !
      Si votre disque est un disque à verrouillage moyen qui n’est pas fixé par 6 vis, il n’est pas compatible avec le kit Geeko. Nous vous suggérons d’acheter le disque chez nous et nous l’installerons à l’avance, ce qui est plus pratique.

    Need a front hub motor that is according to EU standards (Pedelec) with all parts. Motor, sensors, brakesand if possible battery. Below our Bike

    The final product is ready and we are sending the first units to Europe to dealers. We exposed it at the Eurobike 2023.

    1. amber says:

      Hi, please kindly check for our front kits and select the suitable model.

      Any other questions please feel free to let me know.

  12. Diego says:

    Whats the limitation for the tyre width? My tires are 26″ 50mm width, and I see they wouldnt fit. But I cannot understand why… is it because of the provided rim that can only fit up until 42mm tyres?

    1. amber says:

      Hi, the rim supports max 60mm tyre. Because the British standard of 2.35 corresponds to the French standard of 60MM. Sorry there is the mistake in the blog.

      1. Diego says:

        Thank you very much 🙂

    Bonjour, mon VTT Decathlon RR 520 S est il compatible ?
    Si oui pouvez vous me dire quelle configuration choisir.
    Je pensais à celle ci :
    Prime25078R , 9S , 584-27,5″-650B

    1. amber says:

      Bonjour, après avoir vérifié les photos de votre vélo, nous avons constaté que notre kit convient à votre vélo. Veuillez sélectionner le prime-25078R avec une taille de roue de 27,5″.

      Je vous souhaite de bons achats !

  14. Dean Teasdale says:

    Hi, I see these size requirements, but your cart also asks to select Cassette from 7s to 12s, my Cassette has 8 different sprockets, which of these should I select?
    Also it asks to select from a list of Prime25078R etc, what do these mean?


    1. Senquan says:

      Please select “8S”.
      Prime25078R means the battery is Prime 7.8AH, and motor 250W rear.

  15. Omar says:


    Funktioniert das Kit auch für Reifen ohne Disk break (sprich normale Felgenbremse) ? Im Installationsvideo tut man die scheiben bremse ja vom alten Rad abmontieren und ins gelieferte einmontieren. Kann man bei anderen Bremssystemen das einfach lassen?

    LG Omar

    1. Senquan says:

      Hallo, Ja Geeko Kit ist auch kompatibel mit Felgenbremse.

  16. Juri Bassauer says:


    ja wir möchten die anpassung auf 130mm hinten nutzen.

    wird dies eine erneute bezahlung erfordern falls ja bitte ich sie uns dies mitzuteilen damit wir alles erledigen können.

    Es wäre auch sehr schön wenn sie uns einen vorausichtlichen Liefertermin mitteilen könnten.
