Speed booster adapter Ninebot ZT3 Pro E/D

The Speed booster adapter Ninebot ZT3 Pro E/D is a custom-fit speed unlock that makes it possible to release the hidden performance of your electric scooter. With this adapter, you can unlock a maximum speed of up to 35 km/h when the battery level is 100%, while the scooter continues to work with the original software and Ninebot's official app.

The product is designed as a plug-and-play solution, which means no programming, no firmware modification and no third-party apps are required. After installation, you retain full functionality in the Ninebot app, including display of battery status, riding mode and system information. The updated version also eliminates the previous overspeed alarm, giving a quieter and more pleasant riding experience.

The adapter is built with durable materials and a reinforced PVC cable for a long life and stable signal transmission. The connectors consist of a 6-pin male and female that ensure a fast and reliable connection without play. The product is compatible with the latest firmware versions and can be used immediately after installation.

Important to note is that the speed may gradually decrease as the battery level drops, which is normal for the Ninebot system. Maximum performance is achieved at full charge.

If your electric scooter is the German version, you must choose the Ninebot ZT3 Pro D variant of this adapter. For other markets, the ZT3 Pro E version is used. Choosing the right version is essential for correct function and compatibility.

This speed booster is the perfect choice for anyone who wants to upgrade their Ninebot ZT3 Pro in an easy, discreet and reversible way. Order today from Wheelyshop and take control of your riding experience.

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.
