eBike firmware Updates
eBike 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.
Absolutely amazing. Made riding a lot more enjoyable.
Let’s be honest 15mph is way too slow for the road , bought the chip and the bike is alive , customer support from the guys is amazin , emails answered quickly regarding tech support , fully recommend them .
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 🥵
A bit fiddly to fit but works really well. Impressed.
