A real 4-stroke quad, sized and governed for young riders
The Apollo DB-21 70cc dirt bike is built for first-time and beginner young riders. It runs on a 70cc air-cooled 4-stroke engine and uses a semi-automatic 4-gear transmission, so the rider shifts gears without using a hand clutch.
Factory training wheels add balance and help kids learn control on dirt and grass tracks. The strong steel frame, front hydraulic forks, and rear coil spring shock keep the ride stable on bumps and small jumps.
This model is CARB approved for California buyers, making it legal for sale in California under emissions rules. Kick start keeps the bike simple and reliable for outdoor use.

Rated 4.5 / 5 by 255 buyers
Bought this for my 9-year-old and he's obsessed. The adjustable speed limiter let me start him slow then open it up as he got confident. Arrived crated and well-packed.
Was nervous ordering a $1,200 ATV online but their phone support walked me through everything. Shipping was free and showed up in 5 days. Runs great.
Questions, answered
Yes — it's built youth-first. It includes an adjustable speed limiter so you control top speed, a wireless remote shut-off so a parent can stop the ATV instantly, and a tether kill switch. We always recommend a helmet, supervision, and gradual speed increases as your rider gains confidence.
The ATV ships about 70% assembled in a protective metal crate. Final assembly (handlebars, wheels, mirrors, fluids) takes most people under an hour. Prefer it ready to ride? Add the Pro Assembly + Safety Check option and a certified technician fully assembles, tunes, and road-tests it before it ships.
