What are the main differences between the Vika X and the Vika+ Flex?

The main differences from the previous model include the addition of hydraulic brakes for superior stopping power, an upgraded display for clearer information, turn signals, a slate gray color option, a horn, and the use of a torque sensor for smoother and more responsive power delivery. The throttle is now located on the right-hand side of the handlebars for easier access, and the color accents have been changed to black instead of chrome for a sleek, modern look.
