My bike suddenly lost power while I was riding. What could cause this?

A sudden power cut-off during a ride can be caused by:

• The battery having unbalanced or dead cells, leading to an inability to deliver consistent power under load.

• A fault in other electrical components like the 5-in-1 connector, the pogo pins connecting the battery, or the bike's controller.

• It's helpful to note if the bike completely shut off and won't turn back on, or if it just cut out but could be powered back on shortly after. Diagnosing the specific component causing the issue is necessary, and the solution will involve replacing that faulty part (which could be the battery, controller, wiring, etc.).
