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). 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. With this Premium Bluetooth version, you can control speed, monitor rides, and easily adjust settings through the Speedbox app.

This tuning kit is compatible with any of these motors;

Brose Specialized (any specialized brand bike)

Brose SRAM 

Brose S Mag,

Brose T, C or S

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. 

Note: compatible with all Specialized eBike models (except SL versions) and eBikes equipped with Brose SRAM, Brose S-Mag, S, T motors.

Fantastic service. Mega quick delivery.
Once I got the crank off it was 5 minutes to fit and set up on the app. It’s transformed my Vado turbo 4.0.. Doesn’t take away that you still have to work which is great. But it totally takes away that lag when you go down hill and up the other side. It’s seamless. Would thoroughly recommend this for any e-bike.

Love it!! the bike is now something special thanks to adding a little extra power at the top end. Had a problem with the first unit but sent an email about my problem and the guys sent a replacement without issue. Thanks for the quick turnaround and now really enjoy uphill miles.
