Tuning for the Giant eBike range is now available!
To tune your Giant ebike, we connect it to a laptop and update the firmware. This process enables you to establish a custom speed limit of up to 70kph without requiring any hardware modifications. This can be achieved by adjusting the wheel circumference value in the Giant firmware to a custom value based on the desired speed. It's important to note that if you have a speedometer on your ebike, the reading will be incorrect by the ratio of the original circumference to the new value. For example, if you change the limit to 50kph, the circumference is halved, which means that when the speedometer displays 20kph, you will actually be traveling at 40kph.
It's worth noting that this tuning is available for Giant Syncdrive Pro, Sport, Core & Life Motors. Additionally, it's important to never perform any software updates after unlocking the custom speed limit. The changes made are entirely reversible*, should you ever need to return to the original settings for any reason, such as warranty claims or selling the bike.
*Installing Giant firmware updates to you bike after it has been unlocked can make it difficult or even impossible to remove the speed modification.
