03Steps
The “removable” battery is really a bolted-in pack. Removal takes a T40 and a T50 Torx. Owner video: Sondors MetaCycle battery removal and replace.
Removal
On the side without the charging port, remove the two T40 bolts from the battery cover.
Remove the battery. The battery compartment also hides the 5 A blade fuse, so this is a good time to check it.
Reinstall
Reverse steps 1–7. Slide the battery in carefully: it can tilt or jam on the way in.
Wake the battery up: connect the battery activator or plug in the charger. This powers the internal relay (solenoid) so the battery can feed the controller and motor. You’ll hear a click inside the bike.
TODO: bolt torque values for the cover and brackets aren’t documented anywhere yet. If you know them (with a source or a photo of the manual), please share them.
