The Razor MX350 offers a top speed of 14 mph, 30-minute runtime, 140 lbs max rider weight, and 12-inch tires for kids aged 8+, while the MX650 provides 17 mph, 40 minutes runtime, 220 lbs capacity, and larger tires for teens 16+ and lightweight adults.
Razor's MX350 and MX650 are popular entry-level electric dirt bikes designed primarily for young riders seeking backyard fun. The MX350, with its 24-volt system and 350W motor, hits up to 14 mph and supports riders up to 140 lbs, making it ideal for kids around 8 years old. Its compact size features 12-inch tires front and rear, a seat height of about 17 inches, and a lightweight build around 77 lbs for easy handling. Runtime is approximately 30 minutes under ideal conditions, perfect for short play sessions on grass or pavement.
The MX650 steps up with a 36-volt, 650W motor, reaching 17 mph and handling up to 220 lbs, suitable for teens 16+ or smaller adults. It has bigger tires—often 14-inch front—and a higher 22-inch seat height, weighing around 106 lbs. Runtime extends to 40 minutes, offering more trail time. Both models prioritize safety with basic suspensions, but they're limited for serious off-road use due to short runtimes and lower speeds. For families in the US wanting more power without the toy-like limitations, TSTE Bike's dirt bikes provide robust alternatives.
