GoBike 12 Inch Controller – Replacement Motor Controller for Kids Electric Balance Bike

The 12" Controller is the genuine replacement motor controller for the GoBike 12" Ebike for Kids (Ages 2–5).

The controller is the "brain" of the e-bike — it manages power delivery from the battery to the hub motor and reads the throttle input. When a controller fails, the bike often won't accelerate smoothly, cuts out under load, or stops responding to the throttle altogether.

If your GoBike 12" has lost power and the battery and motor both test fine, the controller is usually the next part to replace. This is the exact-fit unit for the GoBike 12" electric balance bike — not a generic substitute — so the wiring and connectors match straight out of the box.

Lightweight at just 2kg and simple to swap, a fresh controller is one of the most affordable ways to bring a kids electric balance bike back to full performance.
