MotoTec Big Alien 50cc 2-Stroke Kids Gas Dirt Bike

The MotoTec Big Alien 50cc Kids Dirt Bike is a fun, beginner-friendly gas mini bike designed to give young riders a real off-road experience. Powered by a responsive 50cc 2-stroke engine, it offers quick acceleration and solid torque compared to similar 4-stroke starters. With a pull-start ignition, improved carburetor, and fully automatic twist-and-go transmission, it’s easy to operate even for first-time riders. Built on a strong steel frame with telescopic forks, rear mono shock suspension, knobby tires, and rear disc brakes, this bike is ready for backyard tracks and light trail riding in wet or dry conditions.

MotoTec MotoTec Big Alien 50cc 2-Stroke Kids Gas Dirt Bike Features

Fast, torquey 2-stroke performance – The latest 50cc 2-stroke engine delivers lively power and strong low-end pull, making riding exciting but still manageable for beginners.

Easy pull-start ignition – A simple pull-start setup with an improved carburetor helps the bike start quickly and reliably.

Fully automatic twist-and-go riding – The auto centrifugal transmission eliminates shifting, so riders just twist the throttle and focus on control.

Built solid for beginner terrain – Steel frame construction supports growing riders and stands up to regular outdoor use.

Comfortable, controlled suspension – Telescopic front forks and a rear mono shock help smooth bumps and keep the ride stable.

Confident stopping power – Rear disc brakes provide consistent braking control for safer starts and stops.

Aggressive motocross styling – Alien-inspired plastics and big-bike attitude give kids a dirt bike that looks as cool as it feels.

They Stood By Me

I was a DIY solar power wannabe... that is 'til I connected with Manny... The man's a prince! He not only knows his stuff; he walked me through all things electrical. To make sure I had all I needed... he gave me his cell phone # to text him anytime I got confused... nights and weekends included. The prices were very competitive... definitely go with Manny -- you won't go wrong!

Bruce D.

Awesome Service!

I am always hesitant to buy things at places I have never shopped... I want to give a shout out to Manny who with great patience and knowledge helped me get my orders... I felt valued as a customer and I will definitely be back in the future. I highly recommend them, they make you feel like family.

Jennene A.

Real Person, Honest Service.

I'm about to go off grid. I called Manny, he walked me through everything so I could truly understand what I needed and never tried to upsell me. He was honest and made a customer for life.

Ray B.

Easy Return

I would personally like to thank Manny... I purchased the inverter and decided I needed to return it... Manny was very understanding and went out of his way to help me return the product and not even have to pay for shipping return. He gives this company reputation, honor and quality customer service!

Roger V.

Totally Off Grid.

I have been talking with Manny the owner... He has not only helped me design a system but he's been assisting with the install and components. I am super pleased so far with the assistance.
