Razor Electric Dirt Bikes: How Fast Can You Go?

Razor offers a range of electric dirt bikes, including the MX350, MX500, and MX650 Dirt Rocket models. These bikes are designed for off-road adventures, combining performance with motocross design. The top speed of the MX350 model is 14 mph, while the MX500 and MX650 models are capable of higher speeds, with some users reporting speeds of up to 27 mph. The bikes feature adjustable handlebars, disc brakes, and powerful motors, delivering an exciting and super-charged riding experience.

The Razor MX350 Dirt Rocket's speed and range

The Razor MX350 Dirt Rocket is an electric-powered dirt bike designed for kids and teenagers aged 8 and above, with a maximum rider weight of 140 pounds. It is a scaled-down, electric-powered dirt bike, combining top-notch performance with an authentic motocross design. The bike's high-torque, chain-driven electric motor powers riders up to speeds of 14 mph (22 km/h) for up to 30 minutes of continuous use in the default high-speed mode. The low-speed mode offers a maximum speed of 10 mph (16 km/h) and up to 60 minutes of continuous use. The bike's rechargeable 24V battery system takes around 12 hours to fully charge.

The MX350 Dirt Rocket features an adjustable-angle, riser-style handlebar, 12" spoked wheels with pneumatic knobby tires, and a retractable kickstand. The rear-wheel drive delivers greater power and traction, while the twist-grip throttle and hand-operated rear brake provide simple, intuitive hand controls for younger riders. The front and rear disc brakes provide ample stopping power, even at high speeds. The authentic motocross frame geometry scales down the dirt bike to size, while the high-torque, rear-wheel chain drive delivers increased power and traction.

The Razor MX350 Dirt Rocket is a great choice for those who want to experience the thrill of dirt biking without the noise and pollution of a gas-powered bike. It is easy to control and has a comfortable seating position, making it accessible to riders of all skill levels. The bike's overall performance and affordability make it an excellent entry-level electric dirt bike.

The MX350 has a maximum operating range of 7 miles, with a run time of up to 30 minutes on a single charge in high-speed mode and up to 60 minutes in low-speed mode. The bike's electric motor is virtually silent, making it ideal for riding in quiet neighbourhoods or parks. The pneumatic knobby tires can handle various terrain, from soft dirt to muddy conditions, providing maximum support and performance for off-road adventures.

The MX500's speed and voltage

The Razor MX500 Dirt Rocket is an electric-powered dirt bike designed for off-road adventures. It features a high-torque, variable-speed motor, large pneumatic tires, and hand-operated dual disc brakes for enhanced control.

The MX500's electrical system is powered by a 36V (three 12V) sealed lead-acid, rechargeable battery. The voltage of an electric motor determines its speed, and the MX500's 36V battery allows for a faster top speed compared to lower-voltage options.

The relationship between voltage and speed is directly proportional; increasing the voltage will result in a higher speed. For example, a 24V motor drawing 10 amps produces 240 watts of power (24 volts x 10 amps = 240 watts). If the voltage is doubled to 48V, the power output quadruples to 960 watts (48 volts x 20 amps = 960 watts).

It is important to note that while increasing voltage can enhance speed, it also increases the amount of heat generated. Additionally, the amp output of the batteries, rather than the voltage, is typically what will cause an electric motor to "fry" or burn out. Therefore, it is crucial to monitor the amp output when modifying the voltage to avoid overloading the motor.

The MX650's speed and design

The Razor MX650 Dirt Rocket is a high-performance electric-powered dirt bike with Supercross-inspired design elements. It is powered by a 650W variable speed motor, which can generate speeds of up to 17 miles per hour. The bike's 36V onboard battery pack allows for up to 40 minutes of continuous operation, though this may be significantly decreased when riding on non-flat terrain.

The MX650 is designed for older children and young adults, with safety features including hand-operated front and rear disc brakes, and twist-grip acceleration control. The adjustable riser handlebars ensure a customized fit for riders of different sizes.

The MX650's design also includes authentic dirt bike frame geometry and large pneumatic tires, which deliver a super-charged off-road experience. The high-torque, variable-speed motor provides increased torque and power for tackling hills, while the large tires offer improved stability and traction when riding on uneven surfaces.

While the stock MX650 offers impressive performance, some users have sought to modify their bikes to increase speed and runtime. Upgrading the motor to a 48V 1600W model, for example, has been reported to increase top speeds to 31 miles per hour. However, it is important to note that modifications may void warranties and compromise safety if not performed correctly.

The MX350's battery and age range

The Razor MX350 Dirt Rocket is designed for kids aged 13 and above, but most users have found it better suited for 6- to 8-year-olds. The bike has a 24V (two 12V) sealed lead-acid rechargeable battery pack, which delivers 30 minutes of runtime. However, some users have reported getting 40-45 minutes of runtime, especially younger and less heavy riders. The battery takes 4-6 hours to charge, which some users have criticised.

The bike's battery life depends on how well it is used, maintained, and stored. While the MX350's battery quality has been upgraded due to technology improvements, the running time remains the same. Some users have reported owning the bike for 4-5 years before the battery fails to hold a charge, while others experienced failures much sooner.
