A stock 12V Power Wheels goes 5 mph in high gear and 2.5 mph in low. Most other ride-on brands are rated close to that same 5 mph, and a few models from Ryder and Freddo run 9 to 12 mph from the factory. This post covers the stock speeds of the vehicles we support, what the speed limits are in the U.S. and Europe, how much upgrades add, and how to tell when a car is too fast for the kid driving it.
How Fast Does a Stock Power Wheels Go?
Current Fisher-Price Power Wheels two-seaters are rated at 2.5 mph in low, 5 mph in high, and 2.5 mph in reverse. The Power Wheels Jeep Wrangler, Dune Racer, and Hot Wheels Racer all carry those numbers. Each one has a parent-controlled lockout that holds the car in low speed until you remove it, and the two-seaters carry a 130 lb weight limit.
Those ratings assume flat, hard ground and a fully charged battery. Grass, hills, a heavier driver, and an aging battery all pull the real speed down. A car with worn gearboxes or tired motors can run well under 5 mph even on pavement, and our guide on why a Power Wheels goes slow walks through how to find the cause.
Stock Speeds of Ride-Ons We Support
The table below lists the top speed each manufacturer publishes for its vehicle. Where a car has two forward speeds, both are shown.

Which Ride-On Toys Are Fastest Out of the Box?
The fastest stock ride-ons we support come from Ryder and Freddo. Ryder rates the Ryder Drifter 2.0 go-kart at 12 mph, the Ryder Toys 24v All Wheel Drive Buggy at 8 to 10 mph, and the Ryder Lamborghini Aventador SVJ at up to 10 mph. Freddo rates the Freddo 24v Buccaneer XXL at 9.3 mph, and it's built for kids 6 and older with a brushless motor and air-filled rubber tires.
Most of the rest sit right around 5 mph, including several 24V models. The Peg Perego Polaris RZR 900 and the Kid Trax 2021 Ford Bronco match the Power Wheels 2.5 and 5 mph settings. The Freddo 24v Can-Am Maverick and the Dynacraft 24v Trailrider are rated at about 5 mph, and the standard Freddo 24v Buccaneer Dune Buggy comes in a little higher at 5.6 mph.
A higher voltage doesn't guarantee more speed. The Bravo Monster Jam 24v Grave Digger and the Adventure Force 24v Thunder Tank both run about 5 mph, and the Rollplay 24v Monster Truck tops out at 4.1 mph and ships set to its 1.86 mph low speed. Those heavy bodies are geared for pulling power, which our post on 12V vs. 24V ride-on toys explains in more detail.
The ML Toys Fire Truck was built with more speed in mind. It ships with twin MLToys Performance 550 motors and upgraded gearboxes, and the Fire Truck upgrade parts collection has 18V and 24V conversion kits for when your kid is ready to go faster.
Is There a Legal Speed Limit for Power Wheels?
The United States has no federal speed limit for ride-on toys. The mandatory U.S. toy safety standard, ASTM F963, covers the electrical side of battery-powered ride-ons, including wiring, switches, circuit protection, overheating, and chargers, but it doesn't cap speed. In a 2022 letter to the ASTM toy committee, CPSC staff recommended adding speed limits like the ones Europe uses.
Europe sets speed limits through the EN 71-1 toy standard, which the UK also uses. As CPSC staff summarized it, electric ride-ons for children under 3 are capped at 6 km/h (3.7 mph). For ages 3 to 6, the cap is 6 km/h, or 8.2 km/h (5.1 mph) if the toy has a two-position limiter that holds it to 6 km/h in one setting. Ride-ons for kids 6 and older are capped at 16 km/h (9.9 mph). A revised edition, EN 71-1:2026, was published this year.
A stock Power Wheels fits inside those European numbers. Its 5 mph high gear stays under the 5.1 mph cap for 3 to 6 year olds, and its 2.5 mph lockout works the same way as the two-position limiter the standard describes.
Speed also affects how a vehicle is classified. CPSC staff list maximum operating speed as one of the factors that separate a ride-on toy from a youth ATV, which falls under different federal rules.
Ride-ons are toys, and they don't belong on public roads. EN 71-1 excludes electric vehicles meant for public roads or sidewalks, so keep them on private property, away from streets and driveways with traffic. Once you change the voltage, motors, or gearing, the car no longer matches the setup the manufacturer designed, and the safety decisions after that point belong to you.
How Fast Can a Power Wheels Go With Upgrades?
Speed upgrades work through voltage, motors, and gearing, and each one does a different job. More voltage spins the motors faster. Stronger motors turn that voltage into usable power without burning up. Taller gearing trades some low-end pull for more top speed.
Voltage is the usual first step on a Power Wheels. The 18 Volt Conversion for 12 Volt Power Wheels wires a 12V and a 6V battery together, fits most 12V Power Wheels battery compartments, and lets you switch back to 12 volts whenever you want. The upgraded batteries collection has other packs and chargers for different vehicles.
Stock motors in most Power Wheels are built for 12 volts. The Matched Pair of 550 12-18v Performance Motors are warrantied up to 18 volts and drop into any vehicle that uses 550 motors. For bigger jumps, the 775 motors in our Stage III and higher kits handle up to 24 volts. Other brands have their own versions, like the Stage III Speed Motors for Peg Perego RZR 900 and the Stage III Speed Motors for Dynacraft 24v Trailrider. The motor upgrades and motor and gearing tuned systems collections group these by vehicle.
Gearing sets the ceiling. The Stage V kits swap the stock 72 tooth first gear for a 66 tooth hardened steel gear and pair it with a 22 tooth steel pinion, which gives the lowest gear ratio and highest top speed we offer for any ride-on. You can get it fully assembled as the Stage V Super Speed Motors/Gearboxes for Jeep Wranglers, or as the Stage V D.I.Y. kit for 7R gearbox cars like the Arctic Cat, Hurricane, Escalade, and two-seat F-150. Because of that ratio, Stage V is for pavement and light gravel only, with no passengers or added weight.
ML Toys publishes real speed numbers for several kits. On the Kid Trax 1969 Bronco, the Level I kit raises top speed to 6 mph, Level II to about 8 mph, and the 18V Level III to about 10 mph, all starting from a 3 mph stock car. You'll find all three on the Kid Trax 1969 Bronco tuned kits page. The Adventure Force 24v Tank Motor Upgrade Package and the Grave Digger package each take their trucks from 5 mph to 8 or 9 mph.
Drag racers push well past these numbers with purpose-built cars, and that's a separate hobby with its own parts and rules. Our post on getting into Power Wheels racing and the racing parts collection are the place to start for that.
What Breaks When You Add Speed
The first gear is the weakest part in a Power Wheels 7R or Phoenix gearbox, and it's usually the first thing to strip when you add voltage. We strongly recommend steel first gears at 18 volts or more, and on the Fire Truck the Firetruck 24v Conversion Kit requires them. The Power Wheels Steel First Gear w/ 2 Steel Ball Bearings is cut from one solid piece of heat-treated steel and carries a lifetime warranty.
Heat is the next problem. Motors running at 18 volts get hot fast, and the 550 Cooling Fan Kit runs fans over heatsinks to pull that heat away. Some ride-ons also ship with a low-amp self-resetting breaker that trips over and over once you add power, so we recommend swapping in the Self Resetting 35 amp Breaker. If your car uses fuses instead of a breaker, leave the fuses in place. The electrical upgrades collection covers the rest of the wiring side.
Power tool batteries need extra care. Our performance motors aren't rated for lithium batteries unless you add the 18-20v Lithium Soft Start Low Voltage Module. Expect shorter run times as voltage goes up, too, since the motors draw more from the same battery.
Traction matters more at speed. Hard plastic tires spin on pavement and wear down quickly, so a faster car often needs a tire swap from the tires and wheels collection. Our post on plastic vs. rubber tires explains the trade-offs.
How Fast Is Too Fast for a Kid's Ride-On?
A ride-on is too fast when your child can't steer it and stop it on their own every time. Our product notes say the same thing: we don't recommend adding speed until your child is ready to drive the car themself. Age gives you a starting point. The European limits allow 5.1 mph for kids 3 to 6 and 9.9 mph for kids 6 and older, and the fastest stock models in the table above are rated for older kids, like the Buccaneer XXL at ages 6 and up.
Upgrades can also take away the parent remote. Many imported ride-ons rely on a remote for younger drivers, and aftermarket speed controllers like the Titan Electronic Speed Control often won't pair with the original remote. The Buccaneer XXL doesn't come with a parental remote at all. If your child still needs you on the remote, they aren't ready for a faster car.
Weight limits still apply after an upgrade. Stock Power Wheels two-seaters are rated for 130 lb, Stage V kits are meant for one driver with no added weight, and our speed control isn't recommended for any vehicle and driver total over 160 lb. Stick to the surfaces the parts are built for, too, since tall gearing on grass or hills overheats motors and high speed on loose ground makes a car harder to control.
If you're adding speed, add control along with it. The MLToys Ride-On Speed/Brake Control v2.0 replaces the on/off pedal with a variable throttle and a variable brake pedal, so the car speeds up gradually instead of jumping to full power. It also has an automatic safety brake that kicks in if your child doesn't press the brake.
Supervision, a helmet, and a closed area away from streets matter more as speed goes up. Our post on ride-on safety covers what to set up before a faster car goes out.

Find your vehicle's tuned kits page, such as the Power Wheels Jeep Wrangler tuned kits, and start with the stage that matches how well your kid drives today. Read the Before You Buy and Installation Instructions on each product page before you order, so the motors, gears, battery, and breaker all match the voltage you plan to run.
FAQ
What is the fastest stock Power Wheels?
Current Fisher-Price Power Wheels 12V two-seaters are rated at 5 mph in high gear. Among the other brands we support, the fastest stock ride-on is the Ryder Drifter 2.0 go-kart at 12 mph.
Is there a speed limit for kids' ride-on cars in the U.S.?
No. The mandatory U.S. toy standard, ASTM F963, covers electrical safety for battery-powered ride-ons but doesn't set a top speed, so each manufacturer chooses its own.
What is the speed limit for ride-on toys in Europe and the UK?
The EN 71-1 toy standard caps electric ride-ons at 3.7 mph for kids under 3, 5.1 mph for ages 3 to 6 when the toy has a two-position limiter, and 9.9 mph for kids 6 and older.
Can I put a 24V battery in a 12V Power Wheels?
Only if the rest of the drivetrain can handle it. Stock Power Wheels motors are built for 12 volts, so 24V needs motors rated for it, like our 775 motors in Stage III and higher kits, along with steel first gears. Most owners start with an 18V conversion.
Does a 24V ride-on always go faster than a 12V one?
No. Gearing and vehicle weight matter as much as voltage, which is why the 24V Bravo Grave Digger and the 24V Rollplay Monster Truck run at or below the 5 mph of a 12V Power Wheels.
How do I keep a Power Wheels slow for a younger child?
Leave the high-speed lockout in place so the car stays in its 2.5 mph low gear. For more control on an upgraded car, a variable throttle like the MLToys Speed/Brake Control lets your child ease into speed instead of getting full power at once.
Can kids drive a Power Wheels on the sidewalk or street?
Ride-ons are designed as toys for private property, and EN 71-1 excludes electric vehicles meant for public roads or sidewalks. Keep them in a closed area away from traffic.
