Frequently Asked Questions

Peartune MSO 4.0 for Giant is a revolutionary tuning kit which suppresses the speed limiter of your electric bike.

After installing your Peartune, the display will show actual values such as maximum speed, average speed, distance travelled daily and range. And you can reach unlimited speed.

The tuning kit can be activated directly on your bike’s display. After pressing the 'WALK' or '+ - + -' buttons, from now on you will be able to ride at a speed of 25 mph (40 km/h), 31 mph (50 km/h) and even more than 37 mph (60 km/h).

To deactivate the tuning kit, press the 'WALK' or '+ - + -' buttons again. Your e-bike will then work the same as before installation of the chip.

With the new PearTune 4.0, you can set whether the tuning should automatically be ON or OFF when the e-bike is switched on.

The level of maximum motor support can be set individually with the + and - buttons, in 1mph (1 km/h) steps.

Chip lock ("Lock the Chip" function): A feature that makes the tuning module virtually invisible. If the chip lock is activated by using the + and - buttons at the control element, the tuning chip is locked on the software side so that no one can recognize that a tuning tool has been installed on the e-bike. This means that the e-bike and display will function normally, and the tuning can no longer be switched on. The chip lock can only be deactivated later, and again with a specific + and - key combination.

With PearTune 4.0 you can set an individual activation code. When switching on and off, the display briefly shows whether the tuning was actually activated or deactivated for confirmation.

Compatible with motor: Giant 2022 (Syncdrive Pro) following models: Giant Reign E+ (2022), Giant Trance X E+ (2022) a Giant Trance X Advanced E+ (2022)
