Grip that suits you

Customize traction control to your riding style and needs. It regulates the motor torque and can prevent the rear wheel from spinning. In "Custom riding modes > Advanced", you can adjust the traction in four stages.

Your trick remains

Add the "Trick Check" screen via the display configuration in the eBike Flow app. After completing a recorded trick, the respective maximum values remain visible until you perform the next trick.
