Our take on the MotoTec Big Alien 50cc 2-Stroke Kids Gas Dirt Bike

The MotoTec Big Alien is a 50cc two-stroke gas dirt bike for young riders, with a pull start and a clutchless centrifugal automatic. Its air-cooled EPA-approved engine makes roughly twice the power of a same-size four-stroke, and it tops out around 25 mph. Telescopic forks, a rear mono shock and disc brakes at both ends set it apart from entry-level bikes that often run a single brake. It suits beginners ages 13 and up up to 130 lbs on dirt lots and easy trails; in California it is competition-use only.

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

The MotoTec Big Alien is a 50cc gas dirt bike for young riders on their first motorized machine. It has an air-cooled, EPA approved two-stroke engine with a pull starter and an updated carburetor. The auto centrifugal transmission means the rider doesn't use a clutch or shifter.

Telescopic forks at the front and a rear mono shock absorb ruts and small jumps. Disc brakes at both ends provide the stopping power. The frame is steel, the wheels are 14 inches with outdoor tires, and the padded single-rider seat sits 22 inches from the ground. The handlebars are angle-adjustable.

On a full 1 liter tank, the bike covers 10 or more miles and reaches a top speed of 25 mph. It can be used in wet or dry conditions. It weighs 48 lbs dry. MotoTec recommends it for ages 13 and up with a maximum rider weight of 130 lbs.

Questions and answers

Is the Big Alien good for a complete beginner?
Yes. The auto centrifugal transmission means no clutch and no shifting, so the rider only works the throttle and brakes. The 22-inch seat and 130 lb weight limit suit older kids and young teens rather than small children.
How does it compare with a 50cc four-stroke mini bike?
The two-stroke makes roughly twice the power of a same-size four-stroke, so it pulls harder and reaches about 25 mph. In return it needs pre-mixed fuel, runs louder and smokier, and has a pull start instead of electric.
What fuel does the two-stroke engine need?
It is a two-stroke, so it runs on gasoline mixed with two-stroke oil rather than straight pump gas. Check the mix ratio in the owner's manual before the first tank.
Can it be registered or ridden on public land in California?
No. In California it is classified for competition use only and cannot be registered for OHRV registration, so it is limited to private or closed-course riding there.
What is included with the bike?
The bike ships as a 50cc two-stroke dirt bike with telescopic forks, a rear mono shock, front and rear disc brakes and a 1 liter tank. It is a single-rider bike; check the box contents for tools and paperwork.
How fast does it go and how far on a tank?
Top speed is about 25 mph, and a full 1 liter tank covers 10 or more miles. That is enough for backyard sessions and short beginner trail rides.
