What Age for a Kids Electric Dirt Bike?

Razor's kids electric dirt bikes start at about age 7. The Dirt Rocket MX125 is listed for riders ages 7 and up (its title says 5+, so check the page you're buying from), and the MX350 is listed for ages 8 and up. The SX500 is marketed to teens. Speed rises with each step: 8 mph on the MX125, 14 mph on the MX350, 15 mph on the SX500.

Age by Model (listed)

  • MX125: ages 7+ (bullet text), up to 8 mph, about $218.
  • MX350: ages 8+, up to 14 mph, about $298.
  • SX500: teens, up to 15 mph, about $480.

Readiness Beyond Age

Check that the child can reach and use the hand rear brake, balance at low speed and stop reliably. Use a helmet, gloves and boots from the first ride, and start the MX350 on its low speed setting.

What to Look For

Voltage (6V / 12V / 24V)

Higher voltage means more power, higher top speed, and better terrain handling. Choose based on your child's age, size, and where they'll ride. 12V is the most popular choice for ages 3–7.

Number of Seats

Single-seat models work for one child; two-seat designs are great for siblings or friends. Two-seaters often put more strain on the motor, so look for adequate power.

Terrain

Most 12V ride-ons handle flat grass and hard surfaces. If you have hills, rough grass, or gravel, look for 24V models with high-traction tires.

Safety Features

Look for seat belts, parental lockout switches, low/high speed settings, and parental remote controls — especially for younger or first-time riders.

Battery & Charging

Check battery life (usually 1–2 hours for 12V) and charge time (8–18 hours). Some premium models offer faster charging or higher-capacity batteries.
