NIU Scooter ECU (V3 / V35S / V35NB)

Description

The NIU Scooter ECU (Electronic Control Unit) is the central brain of your scooter, responsible for regulating essential functions such as starting, shutting down, app connectivity, and GPS tracking. Without it, your scooter can’t operate or communicate with the NIU app — making it a vital component for both performance and convenience.

• For the V35S version: You can start your scooter remotely using the NIU key fob, giving you quick access without needing to turn the key manually.
• For the V35NB version: we will also pair you two remote keypads.

• no mechanical key start for both these models

For V3 ecu scooters recommend you to change to V35NB

Note: every country has a different sim card so changing the ecu will result in no more usage of the APP
