After we monitored many battery fires, we decided to build a casing which can sustain lithium fires for typical e-bike batteries: https://www.youtube.com/watch?v=v0NXXfCA2CY

Neat. How do bikes that have the battery entirely inside the metal downtube compare?

We're working on an internal downtube battery too! It's basically the same tech, the batteries work the same, it's just the form-factor which changes
