An electric kids dirt bike is the better first bike for most children under 12. Razor's electric models list 8-15 mph with 40-60 minutes per charge (MX125 8 mph, MX350 14 mph, SX500 15 mph). Gas youth dirt bikes generally run faster and longer, but they need fuel, oil and routine maintenance, and they're loud. Gas top speeds depend on engine size, so check the specific model.
Comparison
- Speed: electric 8-15 mph (listed); gas youth bikes are generally faster, depending on engine size.
- Run time: electric 40-60 minutes per charge; gas runs as long as there's fuel.
- Maintenance: electric needs charging and battery care; gas needs fuel, oil, air filter and chain care.
- Noise: electric is quiet, which matters for neighborhoods and backyards.
- Price: electric $218-$480 for the Razor models shown here.
Which to Choose
Choose electric for ages 7-12, backyard use and low upkeep. Choose gas for older riders who want higher speeds and longer rides and are willing to maintain the bike.

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.
