Both kick scooters and bikes have their learning curves, but some kids might find kick scooters easier to start with due to several reasons:

Balance: Scooters are lower to the ground, allowing kids to easily put one foot down for stability, which can be less intimidating than balancing on two wheels on a bike.

Handling: Scooters generally have handlebars that mimic steering a toy or a scooter they might have used before, making it more intuitive for some kids.

Initial Coordination: The act of kicking off and gliding on a scooter might feel more manageable initially compared to pedaling and maintaining balance on a bike.

Portability: Scooters are typically lighter and easier to maneuver for kids, making them feel more in control.

However, every child is different, and some might find bikes easier due to the support of training wheels, the ability to coast without needing to continuously kick, or simply personal preference. In the end, it often comes down to what a child is most comfortable with and enjoys more. Some might even transition easily from scooters to bikes or vice versa, as the skills involved in both can complement each other.
