MotoTec Big Supermoto 50cc

21 November 2025

The MotoTec Big Supermoto 50cc with large knobby tires is the perfect kids starter dirt bike. The latest generation of 50cc mini bike engines are faster, torquier, more reliable and even easier to set up and start than ever before. 2-Stroke engines are preferred as they provide almost double the power of the same size 4-stroke. Easy pull start, improved carburetor and all of the standard safety features, support and reliability MotoTec provides.

Suitable for both wet and dry conditions. This bike will offer hours of fun in almost any children’s outdoor environment. Built Solid, this bike can handle most beginner terrain. A steel frame, with the ability to bear your child’s weight as they grow, and real outdoor rubber tires separate this bike from similar products. Responsive acceleration, disk brake, motocross styling and big bike attitude, makes this the perfect children’s choice. Simple to ride, it’s fully automatic, so just twist the throttle and go.
