Frequently Asked Questions

Peartune tuning kit removes the 16mph (25km/h) speed limit, allowing the motor to help you at higher speeds. With the speed limit removed, 28-37mph (~45-60km/h) can be expected, depending on the bicycle and gearing.

All readings like actual speed, max speed, average speed, distance etc. are correctly displayed.

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) and even up to 31 mph (50 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.
