Getting the right tire pressure for your kick scooter is important. It is not only the tire that supports the weight of your kick scooter but also the air pressure inside the tire. Tire pressure influences your vehicle performance like driving comfort and general handling behavior. The type pressure for your kick scooter is 45-50 psi or 3.10 - 3.44 bar. You can also see this information in your user manual. It's best to check your tire pressure every month.
A good battery is the most essential feature in any electric mobility vehicle or device. That's why NIU offers a 2-year Battery Life warranty, although it should be more like 3 years before you'll really notice a difference. Let's break it down - All NIU kick scooter batteries are thoroughly tested to ensure you'll reach 500 charging cycles before a noticeable difference in your daily use. If we take the KQi3 Pro as an example, we can see that with a range of 30 miles, a daily commute of ~5 miles, and you charge it every 3 days, then 500 charging cycles can last 1500 days - 4 years! In the NIU app, you can easily find all the information about your battery and charging cycles, a useful and transparent feature not provided by any other manufacturers.
There are several riding modes that you can use for your KQi scooter. The 4 modes are E-Save / Sport / Custom / Pedestrian. You can find this in your user manual. After a long press of the power button to turn on (or off) the device, short press once for the gear switch. Here is the video of how you can switch to different riding modes.E-save mode has a riding speed of up to 15 km/h for your KQi kick scooter. You will need to bind your scooter to the app and activate it by completing the tutorial. Only after this that you can switch to sport mode and get the maximum speed of your kick scooter.
There are instances when you'll wonder why your speed on the controller/ dashboard is different than what is shown in your NIU App.Your dashboard may show you 20 km/h (DE version) or 25 km/h (EU version). However, the NIU app is showing a different speed.The speed shown in the app is the average speed, not the maximum speed.
