New for 2025. This Speedbox works with eBikes fitted with a Bosch Smart System (Gen5) motor + Rim Magnet Sensor. Once fitted, it removes the 15mph or 20mph factory speed limit, allowing you to enjoy faster, unrestricted rides. It can be switched on or off at anytime using the handlebar controls.
This premium bluetooth version offers the easiest way to customise your tuning kit via the Speedbox app (available for iPhone & Android). Within the app you turn the kit off & on, set a custom max speed, see diagnostics & track your rides. This makes it a great option for bikes that don't have a digital display.
Installation Info (Read Before You Buy)
This tuning kit is a moderate to advanced installation, click here to see how it's fitted. It comes with three key components:
• Tuning module
• Replacement speed sensor
• Electromagnet unit
For some bikes, the motor may need to be removed to install the electromagnet. The factory speed sensor is removed and replaced with a wired sensor, which is mounted to the chainstay. If you’re not comfortable working on your eBike’s motor, we highly recommend having it installed by a professional bike technician.
