SpeedBox 1.3 for Shimano EP8

SpeedBox 1.3 for Shimano EP8

Important to note before ordering!

There are two versions available of the SpeedBox 1.3 for the Shimano EP8 model. Please check the status of your electric bike's E-Tube ports:

• If your bike has a free E-Tube port, you can order the standard version.
• If there is no free E-Tube port, choose the +E-Tube port version. (See the guide image. Please note that the location of your bike's ports may differ from the example.)

How does SpeedBox 1.3 work?

SpeedBox is easily controlled using the light switch:

• Lights off: SpeedBox is activated.
• Lights on: SpeedBox is deactivated.

If you'd like to use the tuning independent of the light function, leave the red wire disconnected during installation. In this way, SpeedBox will remain active at all times.

Features and compatibility:

• Activation: Using the light button (light function must be activated)
• Maximum speed: Unlimited
• Displayed speed: Always accurate up to 23 km/h.
• Compatibility:
  • Shimano EP8
  • EP8RS
  • Giant Revolt (always up to 35 km/h)
• Electric bikes that generally do not have a free E-Tube port:
  • Bikes with Di2 electronic shifting
  • Bikes with a frame-integrated ON/OFF switch
  • However, check the E-Tube port status
• Not compatible:
  • EP801
  • EP6
