Rider lifestyle

More trail.
Fewer excuses.

We are riders first and a distributor second. Every module in the shop has been ridden on Cape singletrack, Karoo gravel and Drakensberg passes before it earned its place here.

It was never about the spec sheet. It is the extra lap when your legs are done, the climb you stop avoiding, and the Sunday that ends with a cold drink and a very dirty bike.

04 — Why SpeedBox

Built like
hardware

SpeedBox has been developing these modules in the Czech Republic since 2014. Sealed casings, proper connectors and firmware written for the specific motor.

Plug and play

The harness uses original motor plugs. No cutting, no soldering, no drilling.

Fully reversible

Unplug it and the bike is back to factory in seconds — handy for warranty visits.

App control

B.Tuning modules pair with the SpeedBox app for settings, ride data and updates.

Local stock

Held in Gauteng and shipped by courier, with backup from the distributor.

05 — Fitment

Ten minutes
on the stand

  1. 01

    Identify the motor

    The motor is printed on the drive unit, not the bike brand. Send us a photo and we'll confirm the module.

  2. 02

    Plug in the harness

    Remove the motor cover, unplug the speed sensor, and click the module into line. Around ten minutes with basic tools.

  3. 03

    Ride, then remove

    Switch on and check the display. To return to stock, unplug the module — nothing to re-flash.
