is very good product highly recommend it

Works perfectly! 🙂

Using it for a NIU Mqi-Gt, very nice product, I've mounted it outdoors inside an electrical box and humidity (which was my main problem) doesn't affect it at all. The charging speed is a little bit slower than the original charger but it's not much of a difference.

Sorry, no reviews match your current selections
Needs better manuals, but the equipment is perfect.
Very fast and professional service. I wanted the max. Speed for my MQi GT (45kmh) to be max and so we set the speed for Sport mode to 100%. The result was a GPS speed of 65-70 kmh and 70-75kmh on the display. Two weeks from Hungary….

I own a NQI GTS 2024. After exchanging several messages and receiving clear and helpful responses, I decided to proceed with purchasing the software service. I then sent my controller in to be programmed.
The configured speed settings are as follows:
• Position 1: 50 km/h
• Position 2: 70 km/h
• Position 3: Maximum
With me riding the scooter, it reaches 50 km/h in Position 1 and 70 km/h in Position 2, exactly as configured. In Position 3 (maximum mode), the highest speed I have achieved is 87 km/h, measured on a flat road under ideal weather conditions.
The service itself is excellent. Communication via WhatsApp is fast, clear, and very polite. I also think it was a very smart decision to purchase the limiter, allowing me to disable the highest speed position whenever necessary, just to be on the safe side.
Overall, I am very satisfied and would definitely recommend this service to friends.
Advertised and confirmed an improvement if 20 km/h… Actually 10 km/h. Also do not think lightly about removing the controller.
