Software Updates
Software 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.

The product works perfectly and is great.
Works like a charm. Easy to fit and has cut my commute from 28mins to 18. Chews through the battery a bit more but to be expected. No dreaded error codes so far, very happy.
Quick delivery
Very easy to fit with clear instructions and the settings are straight forward
Does what it says on tin
Very impressed with e-bike tunner , the delivery was very quick .
The volspeed was really easy to install and so simple to use .
I cant believe how much better my bike is to ride now , no more feeling like I'm towing an anchor after 15 mph . I wish I had done it sooner .
If I change my bike I will definitely purchase a chip for it from e-bike tunner straight away
Great delivery
