The chain-driven, variable speed motor gives the Razor MX500 its kick, but because the bike is electric, the motor is super quiet; a distinct advantage over the other gas-driven and noisy scaled-down dirt bikes. The Razor's front fork is easily assembled; universal flat/Phillips head screwdriver and Allen wrenches are included.

Amazon.com Product Description
Essentially a scaled-down motocross bike with an electric motor, the Razor MX500 Dirt Rocket is ideal for teens who want to enjoy the dirt bike experience without breaking the bank. The Dirt Rocket's powerful 500-watt motor carries riders at speeds of up to 17 miles per hour--more than enough for most bumpy dirt trails--and can cruise for up to 10 miles on a single charge. At the same time, the bike's dual suspension and riser handlebars deliver a smooth and comfortable ride regardless of the terrain, so your teen's fun isn't restricted to flat pavement. As a final bonus, the Dirt Rocket's variable-speed, chain-driven motor is extremely quiet, a marked contrast to traditional gas-powered motocross bikes.

Other details include large pneumatic knobby tires for a maximum power transfer, authentic dirt bike frame geometry, a retractable kickstand, and a double-crown fork. The MX500, which requires roughly eight hours to fully charge, is recommended for ages 14 and over and offers a maximum weight limit of 175 pounds. It's also backed by a 90-day warranty.
