Controller NIU KQi3 Sport/KQi3 Pro/KQi3 Max

The controller NIU KQi 3 Sport/KQi 3 Pro/KQi 3 Max is an original-fit control unit developed for the entire NIU KQi 3 series and optimized for a top speed of up to 32 km/h. This controller acts as the heart of the electric scooter and is responsible for power transmission, acceleration, brake response and communication with the system's other components. Perfect as a replacement part in the event of a fault or water damage, or if you want to restore your scooter's original performance.

The controller is completely plug-and-play and requires no programming, flashing or modification. All connectors and mounting points match the original exactly, making installation quick and safe even if you don't have advanced technical experience. After installation, the controller automatically pairs with the NIU app, where you can manage riding modes, view diagnostics, update the firmware and use anti-theft features.

The housing is made of durable metal that effectively dissipates heat and protects the electronics against vibrations and external stresses. Inside are high-quality components and capacitors that ensure stable operation, smooth power delivery and a long service life even with daily use. An obvious choice if you want to buy a reliable, original-like controller for your NIU KQi 3. Order today and get your electric scooter back in top condition.

Electric scooters (e-scooters)
Rules for e-scooters are not fully harmonised across the EU – each member state sets its own requirements. In most EU countries, e-scooters are limited to a top speed of 20–25 km/h for use on public roads, and some countries also require type approval, insurance or a minimum age. Models that exceed the national limits – for example with higher top speeds or stronger motors – may generally only be used on private property. Always check the current rules with the national transport authority in your country before riding on public roads.

Electric bikes (pedelecs)
Across the EU, an electric bike is treated as a regular bicycle if the motor has a maximum continuous rated power of 250 W, only assists while you pedal, and cuts out at 25 km/h (EU Regulation 168/2013 and EN 15194). Such pedelecs require no registration, licence or insurance. The motor may temporarily deliver a higher peak output, as long as the continuous rated power does not exceed 250 W.

Faster or more powerful models (such as speed pedelecs with assistance up to 45 km/h) are classified as mopeds (category L1e-B) and are subject to type approval, registration, insurance, helmet and licence requirements that vary by country. Models that do not meet these requirements may only be used on private property.

We strongly recommend wearing a helmet, even where it is not mandatory.
