Dimension des batteries

Vérifier les dimensions de la batterie avant l’installation

Dimensions batteries SYKLO

Lorsque vous envisagez d’installer une batterie, il est important de prendre en compte les dimensions nécessaires du cadre :

  • La longueur disponible pour accueillir la batterie
  • Le diamètre du tube diagonal pour la fixation de la batterie
  • La forme du tube diagonal pour la fixation de la batterie


Pour un vélo typique de style hollandais, il est préférable d’installer la batterie sur le tube de selle. Dans ce cas, la longueur du tube de selle doit être suffisante pour accueillir la batterie. Il est important de vérifier que la batterie peut être installée confortablement sans affecter le confort du cycliste.

Check battery dimensions before installation

Dimensions batteries SYKLO

When planning to install a battery, it’s important to take into account the necessary frame dimensions:

  • Available battery length
  • Diameter of down tube for battery mounting
  • The shape of the down tube for battery mounting

For a typical Dutch-style bike, it’s best to install the battery on the seat tube. In this case, the seat tube must be long enough to accommodate the battery. It is important to check that the battery can be installed comfortably without affecting the rider’s comfort.
