The lightweight and stable SporTrike Boomerang balance bike helps children aged 3 to 5 safely develop balance and confidence before their first ride on a pedal bike. Thanks to its convertible 10”/12” frame, 12” pneumatic tires with tread, and a rear V-brake, it offers a comfortable and safe ride. Adjustable handlebars and saddle grow with your child, while soft grips and a contoured saddle ensure comfort.

Safe braking with rear V-brake

The rear caliper brake with adjustable lever and covered cable housing helps children modulate braking force and increases safety.
