Kit for E-Bikes: How to Remove the Speed Limiter and Where to Find the Best Price

If you own an electric bicycle and want to increase its speed beyond the legal 25 km/h limit, e-bike tuning kits are the solution. These devices, also known as "speed-unlockers," allow you to bypass the speed limiter, enabling your e-bike to use its full motor potential. In this guide, we'll explain how these kits work and show you where to find the best deals and the most competitive price on the market.

How Tuning Kits Work

E-bike speed tuning kits work by simply and effectively manipulating the speed sensor signal. The sensor, usually located on the rear wheel hub, sends a signal to the motor to communicate the speed. Once the bike reaches 25 km/h, the motor disengages to comply with legal limits.

Tuning kits intercept and halve this sensor signal. This means when the e-bike is actually traveling at 50 km/h, the bike's electronic system only "reads" 25 km/h, allowing the motor to continue providing assistance beyond the standard limit. It is important to note that the speed shown on the display will be inaccurate.

Types of Kits and Prices

There are several types of unlocking kits, which vary in technology and installation method:

Plug-and-play electronic kits: These are the most common and easiest to install. They connect directly to the motor and speed sensor cables without any soldering. They usually have a switch to turn the unlock feature on or off. Their price ranges from $80 to $200.

Modules or chips: These are more compact and often hidden. They are installed inside the motor housing or frame. These modules are activated by a button sequence on the bike's display. Their cost is generally higher, starting from $150 up to $300.

The best price depends on several factors, including your specific e-bike model (Bosch, Brose, Yamaha, and Shimano motors require specific kits) and the kit manufacturer. To find the best deal, we recommend comparing offers on various specialized websites and e-commerce platforms.

Legal Warnings and Considerations

It is essential to know that modifying the speed limiter of an e-bike makes it illegal for use on public roads in many countries, including Italy. An e-bike with an unlocked speed limiter no longer falls into the "pedelec" category but may be considered a moped or light motorcycle. Consequently:

It cannot be used on bicycle paths.

It cannot be ridden on public roads without a license plate, insurance, and a license.

In the event of an accident, you may not be covered by insurance.

The use of tuning kits is recommended only for private property or for competitive use, where regulations do not apply.
