The MotoTec Alien 50cc is one of the most popular starter dirt bikes for a reason — it's affordable, reliable, and sized perfectly for young riders taking their first laps on dirt. The 2-stroke engine delivers instant throttle response that makes every ride feel exciting.
Who is it for? Kids ages 6-11, up to 100 lbs. The Alien is the entry-level gas dirt bike that gets kids hooked on riding.
Why it works as a first bike:
- 50cc 2-stroke engine — simple, proven, easy to maintain
- Automatic transmission — just twist and go
- Compact frame with low seat height
- Front and rear disc brakes
- Real rubber knobby tires for dirt traction
- Pull-start with kill switch
- Adjustable throttle governor for speed control
Parent-friendly: The throttle governor means you control the max speed. Start at 10 mph for the first few rides, then gradually open it up. The kill switch is within easy reach on the handlebars.
Runs on premix gas/oil (50:1 ratio). Ships 90% assembled — attach handlebars, front wheel, and you're riding.
