Battery StorageUpdated a month ago

When storing your TM-B for three months or longer, follow these recommendations to keep the battery in the best condition:

• Charge the battery to around 80% before storing.

• Disconnect any power cords.

• Power off TM-B. On the Portal’s Walk screen, tap Settings > Power Off. This moves the e-bike from a normal inactive sleep mode to a deep sleep that discontinues battery usage entirely, significantly reducing battery drain. 

  • Note that deep sleep prevents any communication or locking functions.

• Check your storage temperature. Make sure the temperature in your storage location won’t exceed the battery’s rated storage and transport range: -4°F to 140°F (-20°C to 60°C). 

See the TM-B Specifications article for the full environmental spec table.

Waking TM-B back up

• To wake up the e-bike after storage, ensure the battery is installed, then press and release the downtube button under the speaker. 

• You can also wake the e-bike by connecting the charger to the USB-C port on the downtube.
