How to find the correct tuning chip for my Giant eBike?

We’re going to run through the best options for all of the main Giant motors from 2017 onwards. The best way to check what motor you have is to take a look at the specifications provided in your manual or online. You’ll notice that each motor has a different level of torque (nm). Here are the most common examples;

Giant Trance X & Reign E+ with Syncdrive Pro2 (85nm) 

Giant Stance E+  with Syncdrive Sport2 (75nm)

Giant Road E+ & Explore E+ with Syncdrive Pro (80nm), Life, Core 

Giant Fathom E+ with Syncdrive Sport (70nm)

Does this affect my warranty?

It’s important to understand that installing a third party device onto your ebike can potentially void your warranty. However, the options we have discussed above are not detectable and are safe for your ebike. All of them are fully tested on the latest software versions.
