How to avoid error codes

Unfortunately no tuning kits are 100% guaranteed. You can reduce the risk of triggering an error code by following these simple steps:

  • If possible, remove your battery before starting your installation
  • If your eBike uses a smartphone app, switch off automatic updates
  • Once fitted, avoid updating your motor as this increases the chance of detection
  • Remove your tuning kit before doing any software updates
  • Avoid activating/deactivating the tuning kit mid-ride
  • Keep your average speed below 35km/h
  • On some eBikes such as models with the Bosch Gen4 motor, a countdown is required to ensure the correct milage is recorded
  • After a long ride, the countdown will take several minutes. The bike must remain on while this completes
  • When stopping for a short time, keep your foot on the pedal to stop the countdown from starting

How does the warranty work?

In the unlikely event your product develops a fault or defect. We will replace it under warranty. All Speedbox products come with a lifetime warranty.

To claim under warranty, simply contact us here and our team will assist you

Firmware 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.

Installed this on a GIANT TALON, it was a bit of a pain to install because of how the wires are located. Excellent device when in use

I installed the Speedbox 3.2 on my Giant Fathom e-bike, and it made a huge difference — now the bike reaches 31 mph! Honestly, this is exactly how the bike should have come from the factory, especially considering the price I paid. If you want to get the most out of your e-bike’s speed, this is definitely worth it. Mind you you have to put the work in to get to that speed 🥵
