Designed for riders who want to get more speed from their Brose/SRAM powered eBike. This ebike tuning kit removes the 15mph or 20mph factory speed limit, allowing you to enjoy speeds up to 28mph (45kmh).

Compatible with all Specialized eBike models (excluding Gen4 Levo & SL versions) and eBikes equipped with Brose SRAM, Brose S-Mag, S, T motors.

Once fitted, this Speedbox can be switched on/off easily using the handlebar controls. You also have the option to set a custom max speed if you need to. 

Installation is fairly quick and simple with just a few basic tools needed. Once fitted, it's hidden neatly inside the motor cover resulting in a clean, OEM style finish. You can view an installation video here

Software Updates

Updating your eBike’s motor firmware may block or disable your tuning kit.

We recommend avoiding firmware updates especially through service centres unless absolutely necessary. Most updates are optional, and a working eBike doesn’t usually need one.

Keep in mind:

✔ Firmware upgrades can remove tuning compatibility

✔ Tuning is only guaranteed to work with the firmware version available at time of purchase

✔ A blocked tuning kit due to a firmware update is not covered under warranty

If you’re unsure, reach out before updating. We’re here to help you keep your ride running exactly how you like it.
