An Overview of Razor’s Electric Dirt Bike Line

Razor is one of the leading brands in electric ride-on toys for kids. Founded in 2000, the California-based company makes everything from electric scooters and skateboards to go-karts and dirt bikes.

Razor uses quality components on their dirt bikes including pneumatic knobby tires, steel frames, adjustable handlebars, and hand-operated brakes. The bikes have an authentic motocross design but in a scaled-down size suitable for young riders.

The dirt bikes are powered by quiet, high-torque electric motors running on rechargeable lead-acid batteries. With no loud engine noise or exhaust fumes, the Razor e-bikes provide a more family-friendly riding experience than gas dirt bikes.

Razor currently offers seven different electric dirt bike models ranging from intro bikes for 4-8 year olds up to their high-performance MX650 for older teens. The MX400 and MX650 sit in the middle of the lineup and target two very different age groups.
