Then we look at the main differences between them and the advantages of each dirt bike, in turn. Finally, we’ll summarize the pros and cons of both rides, to help you make the right choice for your kids, and for you.

Razor MX125 vs MX350 – Quick Comparison

The Razor MX350 was our Budget Choice when we reviewed the best electric dirt bikes for kids and youths recently. But the MX125 is a great alternative if your child is a bit younger. Let’s take a closer look at how they compare against each other.

In the table below we’ve summarized the main features of each bike in a side by side comparison, to make it easy to see the differences between them.

Razor MX125Razor MX350

Note on Age: Razor’s recommended age for the MX125 is 7 but this is very conservative. An age range of 4-8 (real world guide from many buyers) with parental supervision may be more suitable. Because it is so small – the Razor MX125 seat height is 17″ so older kids would fit better on its bigger brother, the MX350.

Likewise, Razor’s recommended age for the MX350 is a highly conservative 13 but an age range of 5-10 (real world guide from many buyers) with parental supervision may be more suitable. It is bigger than the MX125 but is still a small bike with a seat height of just 20″ – for comparison, a youth size bike may have a seat height around 34″.

Tip: if you’re worried about kids falling off as they learn to ride, you can buy Razor dirt bike training wheels which fit either model (and larger models). They are height adjustable so you can raise them an inch or two as your kiddo becomes more proficient.

See the videos in the next section below for a real world view of the appropriate ages for these bikes.

Main Differences

The biggest difference between both dirt bikes is the size and age of rider that each was designed for.

The Razor MX350 is the bigger brother of the MX125 – its frame is 21% longer, 14% wider and 22% higher. The MX350 also supports a heavier rider (140 lbs vs 110 lbs) and so is more suitable for older children – Razor recommend age 13 for the MX350 compared to 7 for the MX125.

Thanks to a more powerful motor (350W vs 100W) and extra battery (24V vs 12V), the top speed of the Razor MX350 is much higher than the MX125 (14 mph vs 8 mph). However, the battery recharge time is 12 hours compared to 6 hours for the MX125 and the MX350 has a shorter ride per full charge (30 minutes vs 40 minutes)

The MX350 also has adjustable angle, riser style handlebars whereas the MX125 has cross bar reinforced style handlebars.

Pros of Both Bikes

Here is a summary of what we love about both models:

  • Specifically designed for young children with user friendly controls
  • Quick enough to give kids a fun ride but slow enough (compared to gas dirt bikes) to minimize risk of a high speed crash
  • Knobby rubber pneumatic tires (unlike plastic tires of cheap bikes and ride on toys) can tackle many ground conditions including off-road
  • Rear-wheel drive ensures greater traction, stability and balance
  • Steel frame with authentic motocross frame geometry
  • Single speed (simple stop/go) is easier for kids to handle than variable speed
  • No pollution (compared to a gas dirt bike)
  • Quieter than a gas dirt bike and requires much less servicing
  • Razor is a long established US manufacturer – spare or replacement parts are readily available from their website

Cons of Both Bikes

Here is a summary of what we don’t like so much about both models. But most of these issues are common to all electric dirt bikes in this price range:

  • Relatively short battery life. But 30 or 40 minutes is still enough to cover about 7 miles (MX350) or 5 miles (MX125) respectively
  • Battery full recharge time is 6 – 12 hours so charging needs to be planned. Or you could buy spare batteries and switch over instantly
  • No headlights or rear lights so can only be driven in daylight
  • No suspension can make for a less comfortable, bumpy ride if ridden off-road
  • Helmet and protective clothing may be uncomfortable in hot weather (see our Electric Dirt Bike Buying Guide for recommended safety gear)
  • Must be stored in a dry area, due to the electrical components
  • Batteries must not be stored in temperatures below freezing and should be recharged at least once a month


A much smaller frame and lower maximum weight capacity may make the MX125 a good choice for very young kids, especially those who are small for their age and new to dirt bikes. However, we worry that kids may grow out of it all too quickly, due to its very small size and relatively slow speed.

We think the MX350 is a better choice for most young ones – the larger frame, adjustable angle handlebars and higher top speed mean that it should be a suitable size to last kids for several years. Adding training wheels may be a good idea for little ones, until they have found their feet.

The Razor MX350 Electric Dirt Bike is one of the most popular options for a non-gas powered kid’s bike. It’s obvious that Razor has focused on reliability and overall design, but is it actually worth buying? Surprisingly (at least to me), it really is a solid choice for youngsters… plus the kids like it because it looks just like a real dirt bike.

Of course, it’s not perfect and there are some negatives, but then again, nothing really is. It does come equipped with decent knobbies and a powerful-enough electric motor. Unlike gas-powered dirt bikes, the MX350 is super quiet! The top speed of the MX350 is 14mph, fast enough for any mini-daredevil, but also safe enough as it is designed for children.

A 24V sealed lead acid rechargeable battery is included when you purchase the bike and charger. This means no need to wait for a Razor MX350 battery to arrive before your little one can start having fun.

Who is Razor?

If you’re like me, when you hear the company name, you probably think of those little foot-powered scooters. Turns out Razor has a lot more to offer than just those.

Razor has been focused the electric niche. They don’t provide gas-powered options… which is cool because at least they’re focused on what they’re good at.

MX350 Dirt Rocket Features

With endless amounts of various kids’ dirt bikes on the market, it can be confusing to know where to start looking. It can be even harder to whittle it down to the best bike, which is also the best value for money.

Some of the main features of the Razor MX350 Electric Dirt Bike include:

  • Battery-powered: being a battery-powered dirt bike means this bike is environmentally friendly. Unlike gas-powered dirt bikes, the MX350 won’t be releasing pollutant toxins. It also means you can quickly put the battery on charge to allow for more riding time. The battery life of the MX350 is 30 minutes, as reported by Razor. However, many find that their kids can ride much longer… even up to an hour.
  • Large knobby tires: having knobby tires makes this bike perfect for all terrains. Allowing your child to have unlimited amounts of fun, wherever.
  • Twist grip throttle: this allows your child to have complete control of acceleration, which ensures safety as they can control the speed.
  • Hand operated back brake: this allows for extra safety too because the rider is in total control, with easy access to the brake.
  • Adjustable riser handlebars: this is an excellent feature because the handlebars can be adjusted to suit different heights. If you have two children of similar age but different height, they will both be able to use it.
  • Retractable kickstand: this allows for easy storage and helps to prevent scuffs and scratches on the casing of the bike.
  • Foldable foot-pegs. the foldable foot-pegs allow for easy storage and helps prevent breakage.

Positive Reviews

These are just a few of the main pros of the Razor MX350 Dirt Bike. It is a great choice for parents looking to buy their child an electric dirt bike that is safe, well designed, and that will last.

Negative Reviews

As with most things in life, there are some cons. So you will need to weigh both the positives and negatives and see whether you think the Razor MX350 is the bike you want to choose for your child.

  • Compared to a lot of electric dirt bikes, the 30 minutes run time is a lot less battery time. If you are planning on taking the bike out for an extended period, this bike might not be for you as the battery life is only 30 minutes, and then it will need to be charged till full. It’s worth noting that many are able to ride theirs for more than 1/2 hour, but that is what the company promises.
  • This bike does consist of some assembling, so if that isn’t your forte or you would rather not have to do any assembling, then you might want to look into other electric dirt bikes that come ready assembled.
  • Although the adjustable handlebars are on the pros list, they are also a con. If they aren’t appropriately tightened and 100% secure after altering, they could cause severe damage and injury if they become loose while in use… not a big deal, just make sure they’re tightened up.

Where to Buy a Razor MX350 Dirt Bike?

I recommend buying the MX350 from Amazon. You can check out all the bike details to ensure it is the right bike for your child. You can also read other people’s reviews to see if they have any additional information that you should consider.

The benefit of buying from Amazon is the money-back guarantee, and it is one of the world’s most well-known companies, so you know that it is a trustworthy website.

Is the MX350 Worth the Money?

Yes, it’s worth it. Overall, the MX350 Electric Dirt bike is a good all-rounder in the world of kid’s dirt bikes; it is trendy looking, safe, and adjustable for different heights. The speed limit could become an issue as your child gets older, but it’s also a bonus due to safety reasons.

So, if you are on the hunt for a kid’s electric dirt bike, then the Razor MX350 is an excellent option. It is reasonably priced when it comes to electric dirt bikes. Your child is guaranteed to have endless adventures, riding, and fun with the MX350 Electric Dirt Bike.

Your kid won’t stop raving about dirt biking and the fun that it comes with. But you are well aware that he can’t be speeding up and down dirt trails on a gas-powered 50cc at his tender age. So, what do you do to quench his thirst for an outdoor adventure?

With this, you’ll be able to ensure that your little prodigy has all the ingredients for exciting off-road biking without necessarily risking his safety. Razor is a brand that quickly comes to mind when you think of personal electric transport.

In this post, we review one of their offerings, the MX350 dirt bike for kids. It’s been touted as one of the best models you can find in the market today for a young bike enthusiast. But how does it stack up against the competition? Keep on reading for more…

Maximum Speed : 14mphMOTOR: 350W high-torque, chain-driven motor FRAME: Steel with authentic dirt bike geometryBRAKE TYPES: Hand-operated rear brakesBATTERY: 24V (two 12V) Lithium-ion sealed lead acidWHEELS: Spoked 12-inches TIRES: Big, pneumatic knobby tires


The Razor MX350 features a formidable steel frame that can comfortably carry riders weighing 140lbs or less. Measuring 44 by 24.5 by 31 inches, this bike has the geometry of an authentic dirt bike. Its 65lbs weight ensures that your kid remains agile in the rugged terrain.

Overall, the bike has an appealing design that is fit for a professional dirt bike rider. Riser handlebars with ergonomic grips and spacious seat help to deliver a sleek and comfortable ride in all kinds of surfaces; your boy’s fun won’t be restricted to the flat pavement alone.

This bike also comes with a retractable kickstand, as well as folding foot pegs, meaning you’ll have an easy time squeezing it into the corner of your garage. Its frame also allows you to pack it in the boot of the car while transporting it.

Ideally, this bike can be utilized by children up to 13 years of age. However, it is best suited for kids aged between 5-7 years, who will have less difficulty maneuvering it and have the bike grow with them as they get older.

The MX350 is equipped with convenient hand-operated rear brakes that help to improve your son’s hand-to-eye coordination. Just like in a push-bike, engaging the brakes only requires squeezing the handlebar lever.

This makes things quite easy for young riders, although there’s an issue when it comes to scaling up the hills. I feel the rear brake could make do with the extra help of a front brake or a disc to deliver a more stable stopping power.


The MX350 uses a 350W motor that will allow your child to achieve a decent maximum speed of 14mph; just enough to get the adrenaline pumping but nothing dangerous.

This chain-driven motor offers a long lifespan but slightly suffers when it comes to torque.Your kid will lose speed rapidly when ascending inclines! Nevertheless, twisting the handlebar throttle will deliver a smooth but limited acceleration.

One thing that stands out from the chain-driven motor is the low sound profile that it provides.

Unlike gas-powered dirt bikes, this electric transporter ensures that your kid won’t be a nuisance in the neighborhood because of the irritating engine noise.


Just like any other electronic toy, the Razor MX350 comes fitted with a 24V battery that is made up of two 12V sealed lead acid rechargeable system. The battery will require 12 hours of continuous charging when you acquire it before your son takes it out on its first run in the dirt.

This battery will offer your boy almost 30 consecutive minutes of unadulterated fun on a full charge, although the exact duration will be determined by the weight of the rider and the speed at which he’s riding. Usually, the faster the bike goes, the less time there will be to ride.

Generally, the battery will require as many as 8-12 hours to completely recharge when it runs out of power. This is one of the few let downs on the MX350; 8 hours of waiting may feel like an eternity for any young rider who has just been bitten by the dirt bike-riding bug.

Your child will enjoy the versatility that this dirt bike offers on all types of surfaces. The ride remains stable and exciting on dirt trails, grass fields, bumpy roads, as well as gravel, allowing him to go anywhere he wants, and as fast as he wants to.

One thing to keep in mind is that the battery on this bike doesn’t come pre-charged. So, you might want to charge it for 12 continuous hours if you want your excited son to start riding it immediately on the following morning.


The MX350 motocross bike consists of spoked wheels on large 12-inch pneumatic knobby tires for maximum power transfer. The tires are well-treaded to result in a stable ride, even on slippery surfaces, to provide your learning biker with the rider confidence he needs.

These can also be filled using a standard bicycle pump, and the fact that they are air-filled means you need not worry too much about pressure.

What Do We Like?

There are many great features on the MX350 that enable it to leave other rival dirt bikes in the dust. First on the list is the rugged design and authentic motocross feel that the bike offers. Your boy will look like a pro in the making on this amazing two-wheeler.

The ride is generally smooth with simple controls that anybody getting their feet wet can master in a short matter of time. Your inexperienced kid will be riding this mini-machine like a pro after a few test sessions.

The bike is compact enough to be carried in the trunk of a car when you need to transport it. This comes in handy when you have to take your child out to local trails for a greater sense of adventure.

This bike has a sturdy frame that enables your child to remain stable and comfortable throughout the ride. The kickstand is a handy addition that becomes useful when your kid has to take a breather in the trail where there’s no designated place to park the bike.

You’ll also appreciate the 90-day warranty period that the manufacturer offers on purchase of the motorbike. This allows you to have the bike exchanged in the rare case that you end up with a faulty product.
