Legal note

Please be aware that using modified electric bikes, such as those with Speedbox or a Smoothway speedmodule, on public roads may be illegal in some countries. These modifications are strictly prohibited on public roads, cycling paths, and public places, and should only be used on private property, entirely at your own risk. Additionally, using a Speedbox or the Smoothway speedmodule may void your e-bike's warranty. Smoothway does not accept liability for any warranty loss, property damage, or harm resulting from the use of the Smoothway speedmodule.

How does it work?

The speedbox works by altering the signals sent between the e-bike’s speed sensor and its controller(the display on your handelbar). Essentially, it tricks the system allowing the motor to continue providing assistance beyond the standard limit.

As the battery percentage drops, the speedbox will gradually limit the maximum power assistance. For example, when the battery reaches 50%, the speedbox will cap the maximum speed at approximately 28 km/h.

Will using a Speedbox affect my e-bike’s battery life?

Higher speeds can slightly reduce battery range since the motor provides increased assistance. As the battery percentage drops, the speedbox will gradually limit the maximum power assistance. For example, when the battery reaches 50%, the speedbox will cap the maximum speed at approximately 28 km/h.

Shipping

I ship out orders at least once a week, but let’s be real—I usually hit the post office 2-3 times because I know you’re itching to get your stuff. 🚀 Just remember, it’s just me running the show, packing each order with love. As soon as your order is shipped, you’ll get a notification with tracking info. If I could teleport your package, I would—but until then, patience, my friend!
