PearTune MSO 4.0 FLYON TQ

Tax included. Shipping calculated at checkout.
PearTune connects to the e-bike system with compatible and original connectors. The MSO does not need to be configured manually. The entire configuration and adaptation to the respective e-bike is carried out automatically. The MSO connects between the magnetic speed sensor and the motor unit, and between the display and the motor unit. The MSO is powered via the display connection. All speed readings like current speed, maximum speed and average speed are displayed correctly. Only the distance can be displayed a little smaller than it actually is.

The MSO can be activated or deactivated at any time while driving by pressing the "+" and "-" buttons. The device status is indicated by the speed indicator, which shows "9.9"/"2.5" for a short time after enabling/disabling the PearTune, so that the driver always knows whether the device is active or not.

Thanks to original plugs, e-bike tuning can be uninstalled without signs.

The speed limit is removed completely and without side effects. Not just shifted to 50km/h.

The only difference is that from the moment you install it, you, not your bike, determine how fast you go. The maximum speed is only limited by the cadence.

Also available in "STILL ON" version - note this when ordering and we will configure it for you to the Still ON version - the PearTune will then be automatically ON/OFF when your bike is ON/OFF. So no buttons are needed for activation.

Compatible original plugs, extremely small waterproof case. Can be uninstalled without any signs.

Microcontroller based electronics. Automatic setting of all required parameters.
Works seamlessly with HAIBIKE FLYON with TQ motor.
We offer similar ones for all other BROSE, BOSCH, YAMAHA, GIANT and SHIMANO systems.
Unlike similar devices, this device does not show any screen flickering or other unwanted effects. Everything else, except for the removal of the speed limit, remains the same.
The only difference is that you can ride your bike at whatever speed you want.
60km/h with assistance? Just plug in and enjoy!

The MSO can be activated or deactivated at any time while driving by briefly pressing the +-+ buttons once.
