Apollo AG-B21K 70cc Kids Dirt Bike | Semi-Automatic 4-Gear Off-Road
$679 A real 4-stroke quad, sized and governed for young riders
The Apollo AG-B21K 70cc Semi-Automatic Dirt Bike is a small off-road bike made for young riders who are ready to learn shifting without using a clutch lever. It runs on a 70cc air-cooled 4-stroke engine with a 4-gear semi-automatic transmission.
The bike uses kick start and chain drive. Hydraulic front forks and rear coil shock help absorb bumps while riding on dirt paths. Braking uses drum brakes front and rear.
Seat height is moderate, giving growing riders more control than very small starter bikes.

Rated 4.8 / 5 by 283 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.
