A highly recommended tuning module specifically for Yamaha SyncDrive Sport drives, such as those found on GIANT e-bikes. Since it's controlled via an app, the tool offers a wide range of optimization options, including setting the level of motor support to a custom value. The light button allows you to turn the tuning on or off at any time. The e-bike display shows correct data, even when tuning is active—however, the data available via the app is even more comprehensive.
