  3. I have a problem with fitting the battery ks26, the base plate on the frame is drilled in the incorrect position. I recieved on the 18 of May 2022 and reported defect immediately . Still no resolution apart from send bike to China or Italy from Ireland to get fixed why is this the only solution ? The warranty is not being honored ?

    1. Hi Sean,
      thanks for your message. about the aftersale, you have to contact your seller, you didn’t buy from our official website: cmacewheel.com.
      well, usually, if our customers have this problem, we will ask for a video to check the problem, and if any parts are wrong, we will send a new part to replace. We don’t ask to send the bike to Italy or china to repair it, it’s not a good way.
      too much shipping cost.

      andy

  4. Bonjour
    J’ai acheté un M26 et le compteur ne m’affiche ni la vitesse ni les kilomètres parcourus !!

    1. Hi friend,
      if you don’t have cmacewheel bikes, I don’t suggest you use it. because we don’t know it if fit your bike .

  5. Bonsoir

    Votre réponse n’est absolument pas satisfaisante, vous êtes le fabricant donc c’est à vous de m’apporter une solution!
    Votre réaction ne favorise pas le sérieux de vos produits et maintenant je comprends qu’il y est si peu de commentaire positif!

    1. Hi friend,
      if you need me to fix it, you need to pay the money for the new display and shipping. but if you ask your seller, you will get a warranty. that’s why I ask you to contact your seller.
      if you buy on cmacewheel.com, then just contact [email protected] they will settle it for you. If you buy another place, we can’t do a free warranty.
      about the positive comments, this is a place to solve customers’ problems. not for reviews.
      thanks,
      andy
