What is the battery warranty and how should I maintain it?

We offer a comprehensive warranty for our e-bike batteries. For detailed warranty terms, please check our Return & Warranty policy page.

How should I store my e-bike battery during winter or long periods of non-use?

If you plan not to ride your e-bike for an extended period (such as during the winter months), proper battery care is essential to protect its lifespan:

  • Charge it to about 50%-60% before storing; do not store it completely full or completely empty.
  • Disconnect the battery from the bike and store it indoors in a dry, temperature-controlled environment (ideally between 50°F–70°F / 10°C–20°C).
  • Check and charge the battery every 1 to 2 months to prevent deep self-discharge, which can permanently damage the cells.

Is an adult signature required upon delivery?

Yes, for your security and to prevent package theft or loss, all of our e-bike shipments are dispatched with an Adult Signature Required service.
