* Razor’s recommended age for the MX500 is 14+ but this is highly conservative. An age range of 8-14 (real world guide from many buyers) with parental supervision may be more suitable because the seat height is about 10″ lower than on a typical adult dirt bike.

* Razor’s recommended age for the MX650 is 16+ which is also very conservative. An age range of 10-16 (real world guide from many buyers) with parental supervision may be more suitable. Because this dirt bike also isn’t a full adult size – the seat height is 24″ compared to roughly 34″ or more on a regular adult dirt bike.

Main Differences

As the table above shows, both models are mechanically the same bike with the same size frame, except that the MX650 has a larger motor. This gives it a higher maximum speed and a higher maximum weight capacity.

The difference between both bikes is therefore the weight and age of rider that each was designed for.

The Razor MX500 is 2 mph slower than the MX650 and can only carry a rider weighing up to 175 pounds. It is more suitable for those aged 8 to 14 than older teens or adults.

The Razor MX650 is the fastest Razor electric dirt bike. It can carry a rider weighing up to 220 pounds so is suitable for those aged 10 to 16, including some older teens or small adults.

Thanks to a more powerful motor (650W vs 500W) the Razor MX650 also benefits from a higher top speed of 17 mph, compared to 15 mph in the MX500.

Advantages of Razor MX500 Dirt Rocket

Razor MX500 Dirt Rocket
  • MSRP (Manufacturer’s Suggested Retail Price) is about $40 cheaper than the MX650 – but check the actual prices below
  • If you purposely want to reduce risk then the top speed of the MX500 is 2 mph lower than the more powerful MX650, and acceleration is slightly slower too

Advantages of Razor MX650 Dirt Rocket

Razor MX650 Dirt Rocket
  • Higher maximum load (220 lbs vs 175 lbs) means it can cope more easily with teens and even small adults
  • More powerful 650W motor = faster top speed (17 mph vs 15 mph) and slightly faster acceleration
  • Some users who have both models report that the MX650 motor is quieter than the MX500, with the same weight of rider on both.
    Razor don’t publish noise specifications so we can’t be certain this is true. But it sounds very plausible as a larger electric motor will be under less strain and have to work less hard to propel the same weight of rider, compared to a less powerful motor

Pros of Both Bikes

The summary below highlights what we love about both models:

  • Specifically designed for kids or teens
  • User friendly controls
  • Adjustable angle handlebars can adapt to fast growing kids (longer legs)
  • Quick enough to give an adrenaline rush
  • Slow enough (compared to gas dirt bikes) to minimize risk of a high speed crash
  • Large knobby rubber pneumatic tires can tackle many ground conditions, including off-road
  • Dual suspension and dual brakes provide better comfort and safety when off-roading
  • Steel frame with authentic motocross frame geometry
  • Quieter and cheaper to buy than a gas dirt bike
  • No pollution (compared to a gas dirt bike)
  • Requires much less servicing than a gas dirt bike
  • Razor is a long established US manufacturer – spare or replacement parts are readily available from their website

Cons of Both Bikes

The summary below includes factors that we don’t like so much about both models. But note that most of these issues are common to all electric dirt bikes in this price range:

  • Relatively short battery life. But 40 minutes is still enough to cover 10 or 11 miles respectively
  • Battery full recharge time is up to 12 hours so charging needs to be planned (or you can buy a spare battery pack to switch over instantly)
  • No reverse gear – both bikes weigh 98 lbs so can be awkward to maneuver backwards
  • The seat height of 24″ may be too low for very tall teens (and many adults)
  • No headlights or rear lights – can only be driven in daylight
  • Not intended for use on public streets
  • Helmet and protective clothing (see our Electric Dirt Bike Buying Guide for recommended safety gear) may be uncomfortable in hot weather
  • Not as high top speed as many gas dirt bikes
  • Must be stored in a dry area, due to the electrical components
  • Batteries must not be stored in temperatures below freezing
  • Batteries must be recharged at least once a month to keep them fully operational

Owner’s Manual

As the Razor MX500 and MX650 are mechanically identical, apart from the motor, they share the same manual.

The owner’s manual for both the MX500 and MX650 is available in PDF format from Razor here.

NOTE: A parent’s decision to allow their child to ride either the Razor MX500 or the Razor MX650 should depend on the child’s individual maturity, skill and ability to follow rules.
