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.

96 % of my riding is off road coastal paths, but where I used to lag behind my mates on the rd I can now keep up , no more hitting a wall at 16mph , also love the ease of how you can switch it on and off so only use it when needed and At 63 it really helps the old legs
Easy to find what you’re looking for and quick reply if you need any questions answering.
Very speedy delivery from time of purchase.
Absolutely Spot on Company. Fast delivery and simple instructions. Definitely be buying from these again
At the start I thought that I made a mistake bcz it wasn’t working. Then i come to realise that my speed sensor magnet was out of place. Now its working fine and I am happy. Thank you
Easy to follow instructions. Took a bit of time to fit back together with the extra wiring.
Noticed the change straight away. My bike is so much fun to ride now, no more hitting a wall.
Awesome bit of kit!!
