Peartune MSO 4.0 For Brose Specialized Turbo Levo 2.0 | 2.1 | 2.2 Motors

This 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 manipulates the speed signal without altering the motor's power relative to pedaling speed. This guarantees a smooth motor control without speed limit interruptions. Depending on a tuning kit, some determine when assistance stops, while others remove the restriction entirely for continuous support. However, the achievable speed mostly depends on the eBike model. Achievable speed can be calculated using a simple formula:

Speed = Cadence [rpm] * Wheel circumference [mm] * Front Chainring Teeth / Rear Chainring Teeth * 60 [min/h] / 1.000.000 [mm/km]

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). Or one long press of the '+' button in the case of 2.0E Vado.

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.
