Description summary

Unleash the true potential of your Shimano-powered e-bike with the redesigned SpeedBox 1.2. This advanced tuning chip deactivates the speed limiter, letting you ride at unlimited speeds on private property. Featuring all-new hardware and firmware, it´s easily controlled via your bike´s LIGHT button—simply turn the lights off to unlock full speed. Installation is straightforward using original connectors but requires a free E-Tube port on your motor (E8000/E7000/E6100/E5000). Ride without limits

A redesigned chip tuning for your electric bike with a Shimano motor in a renewed design, completely new hardware and firmware.The SpeedBox 1.2 chip tuning allows you to deactivate the speed limiter of the electric bike.

After installing the chip, the actual data up to 23km/h is displayed on the screen of the electric bike.

If you want to monitor the correct speed and all driving data during your ride, we recommend purchasing the SpeedBox 1.2 B.

Tuning for Shimano - You can monitor the actual driving values in our SpeedBox App - right on your phone screen.

Contrary to previous versions, this new product for Shimano motors also connects to the motor´s E-Tube Port.

Therefore, it is necessary that the motor of the bicycle in which you want to install the new version of SpeedBox for Shimano, has a free E-Tube Port.

It is not possible to install SpeedBox products for Shimano without a free E-Tube Port on the motor.

E-bikes that have, for example, a Di2 electronic shifter or a power button integrated into the bike´s top tube:Satellite System On/Off Switch (EW-SW100, EW-SW300) generally do not have an E-Tube Port free.

How does SpeedBox 1.2 work?.

Also this chip is easy to control with the LIGHT button.

When the lights are off, you can ride at unlimited speed.

You can turn off the chip function simply by activating the lights.

If you want to use the tuning independently of the lights, do not connect the red spade terminal during installation, so the SpeedBox will always be active.

If you don´t have lights on your bike, SpeedBox 1.2 will also stay on constantly.

Mounting.

We use original connectors for the production of SpeedBox chips, so the installation of the chip will be really easy and the connection will be correct.

We have written the detailed instructions and made the videos that will allow each customer to install SpeedBox on their own.

Removing the tuning chip is as easy as mounting it.

If you have any problems with the connection, please do not hesitate to contact us.

If you want SpeedBox on a new bike, you must first ride at least 1 kilometer on the bike.

Ideal buyer profiles

The E-Bike Performance Tuner

This rider owns an e-bike with a compatible Shimano motor system (E8000, E7000, E6100, or E5000) and wants to unlock its full speed potential. They are comfortable with making modifications to their bike to enhance its performance beyond factory settings.

The Long-Distance E-Bike

This individual uses their e-bike for long commutes or extensive recreational rides on open roads or paths. They often find the standard speed limit restrictive and want the option to maintain higher speeds to cover distances more quickly and efficiently.

This device provides the ability to bypass the e-bike's speed limiter, directly addressing their need for faster travel over long distances. Its straightforward operation gives them the freedom and assurance to ride at their desired pace, making their journeys more efficient.

The DIY E-Bike Customizer

This person enjoys personalizing and upgrading their equipment. For them, modifying their e-bike is part of the hobby. They look for well-engineered components that integrate cleanly with their existing setup.

The Speedbox 1.2 appeals to their DIY nature by offering a specific, targeted upgrade. The design, which utilizes original connectors, ensures a secure attachment and a professional-level integration that aligns with their high standards for customization and reliability.

Competitive features

When evaluating the Speedbox 1.2, it's important to understand its specific function as a speed-increasing device for Shimano e-bike motors, rather than a traditional cycling computer. Unlike navigation-focused units like the Garmin Edge Explore 2 or Hammerhead Karoo 2, the Speedbox 1.2 is designed for a single purpose: to deactivate the e-bike's speed limiter. This core function sets it apart from competitors that offer GPS tracking, data analytics, and connectivity features.

Where it excels

The Speedbox 1.2 excels in its dedicated function of unlocking the speed potential of compatible Shimano e-bike motors (E8000, E7000, E6100, E5000). | It features a straightforward control mechanism, using the bike's existing LIGHT button to activate and deactivate the speed limiter. | The device is designed for a clean installation using original connectors, integrating directly with the bike's motor system.

Consider alternatives if...

If you require GPS navigation, route planning, or mapping, alternatives like the Garmin Edge Explore 2 or Hammerhead Karoo 2 are more suitable as they are dedicated cycling computers. | For riders seeking comprehensive ride data, performance analytics, or connectivity with sensors and smartphones, this device is not the right choice. It does not offer these features. | This device is motor-specific.

Verdict

The Speedbox 1.2 is a specialized tuning chip for e-bike owners with specific Shimano motors who want to remove the factory-set speed limit for use on private property. It is not a cycling computer and lacks navigation, data tracking, and connectivity. Its value is in its singular, focused ability to increase potential speed. For cyclists needing ride metrics and GPS, a dedicated cycling computer is the appropriate choice.
