Ready to watch your kid tear up the neighborhood? We’re breaking down the epic battle between Razor’s two most popular electric dirt bikes – and trust me, the winner might surprise you.
The Bottom Line (Because You’re Probably in a Hurry)
MX350: Perfect starter bike for younger riders (ages 13+). Think of it as the “training wheels” version – but way cooler. MX500: The beast mode upgrade for serious young riders (ages 14+). This is where things get real.
But hold up – before you click “buy now,” let’s dig into why choosing the wrong one could leave you with one very disappointed kid (and a lighter wallet).
Head-to-Head Specifications: MX350 vs MX500
| Feature | Razor MX350 | Razor MX500 | Winner |
|---|---|---|---|
| Top Speed | 14 mph | 15 mph | MX500 (barely) |
| Battery Life | 30 minutes | 40 minutes | MX500 |
| Dirt Bike Weight | 65 lbs | 98 lbs | Depends on your kid |
| Max Rider Weight | 140 lbs | 175 lbs | MX500 |
| Age Range | 13+ years | 14+ years | Similar |
| Throttle Type | Single-speed (on/off) | Variable speed | MX500 |
| Brakes | Rear only | Front & rear disc | MX500 |
| Suspension | None | Front & rear | MX500 |
| Price Range | ~$400 | ~$500-700 | MX350 |
Speed & Performance: Is 1 MPH Really Worth It?
Here’s where things get interesting. The MX350 carries riders at speeds of up to 14 mph in the default HIGH speed setting, while the MX500 edges it out at 15 mph.
Real talk: That 1 mph difference? Your kid won’t notice. What they will notice is how the bikes handle that speed.
The MX350 Experience
Think Nintendo Switch – simple, effective, gets the job done. The throttle is not modulated, so you either have it all on (full speed) or off (nothing). It’s like driving with cruise control – zero or hero, no in-between.
The MX500 Experience
This is Xbox territory. The variable speed throttle lets riders dial in exactly how much power they want. Perfect for learning control or showing off those smooth acceleration skills at the local dirt track.
Winner: MX500 for versatility, MX350 for simplicity.
Battery Life: 30 vs 40 Minutes (Why This Matters More Than You Think)
The Razor MX500 provides up to 40 minutes of continuous use compared to the MX350’s 30 minutes. But here’s what the specs don’t tell you:
- Charging time: Both take about 12 hours to fully charge
- Real-world usage: Expect 20-35 minutes depending on rider weight, terrain, and throttle habits
- The “dead battery tantrum” factor: That extra 10 minutes could be the difference between “best day ever” and “this bike sucks”
Pro tip: Get a second battery pack regardless of which model you choose. Trust me on this one.
Weight & Size: The Make-or-Break Factor
This is where things get spicy. The MX350 weighs in at 65 pounds making it the best option for younger, smaller riders, while the MX500 tips the scales at 98 pounds.
Why This Actually Matters:
- Can your kid pick it up? A 100-pound bike requires serious strength
- Seat height: The seat height on the MX350 is about 22.5 inches – can their feet touch the ground?
- Storage: Good luck fitting the MX500 in your average garage corner
The harsh reality: If your kid can’t handle the weight, the coolest bike in the world becomes an expensive lawn ornament.
Safety Features: Where Your Peace of Mind Lives
Braking Systems
- MX350: Hand-operated rear brake only
- MX500: Front and rear disc brakes
Before you panic about the MX350’s single brake system, remember it’s 33 pounds lighter and designed for younger, less aggressive riders.
Suspension Showdown
- MX350: Zero suspension (ouch)
- MX500: Full front and rear suspension (ahh)
The MX350 relies on its knobby pneumatic tires to absorb impacts. It works, but your kid’s spine might disagree after a long session.
The Throttle Situation: On/Off vs Smooth Operator
This is huge and often overlooked:
MX350: Single-speed throttle = instant full power or nothing. Great for confidence, terrible for finesse.
MX500: Variable speed throttle = smooth power delivery. Perfect for mastering control and impressing friends.
Real-world impact: The MX350’s all-or-nothing throttle can be jarring for new riders, while the MX500’s variable control helps build proper riding skills.
Age & Size Recommendations: Getting This Right Matters
Razor’s Official Guidelines:
- MX350: Ages 13+, max 140 lbs
- MX500: Ages 14+, max 175 lbs
Our Real-World Take:
- MX350: Perfect for ages 10-14, especially first-time electric bike riders
- MX500: Ideal for ages 13-17, including teens who’ve outgrown smaller bikes
The parent test: If your kid can comfortably handle a regular bike and weighs over 100 pounds, lean toward the MX500.
Price vs Value: What’s Your Money Really Buying?
MX350: Lower:
CHECK PRICE
- Entry-level perfection
- Lower maintenance
- Easier storage
- Great resale value
MX500: Higher:
CHECK PRICE
- Premium features
- Longer lifespan (kid won’t outgrow it as quickly)
- Better performance
- More “wow factor”
The math: Spending an extra $100-200 upfront could save you from buying a second bike in two years.
Which One Should You Actually Buy?
Choose the MX350 if:
- Your kid is 13 or younger
- This is their first electric dirt bike
- Budget is tight
- Storage space is limited
- You want something simple and reliable
Choose the MX500 if:
- Your kid is 14+ or experienced with bikes
- You want room to grow
- Performance matters more than price
- You have adequate storage
- Your kid weighs over 120 lbs
The Plot Twist Nobody Sees Coming:
Consider the MX350 even for older kids if they’re new to electric bikes. The simpler operation and lighter weight make it an excellent stepping stone before upgrading to something more powerful.
Maintenance & Long-Term Ownership
Both bikes are surprisingly low-maintenance, but here’s what you need to know:
Battery replacement: Expect to replace batteries every 1-2 years with regular use (~$50-80) Tire wear: The knobby tires last 6-12 months depending on terrain Chain maintenance: Monthly cleaning and occasional lubrication
Pro tip: Buy replacement parts when you buy the bike. Trust me, something will break at the worst possible moment.
The Final Verdict: MX350 vs MX500
After extensive research and real-world testing, here’s the truth:
The MX350 is the smarter choice for 80% of families. It’s reliable, affordable, and perfectly sized for its target audience. Most kids will have a blast and never miss the features they don’t have.
The MX500 is worth the upgrade if your situation specifically calls for it – older/bigger kids, experienced riders, or when you want maximum longevity.
The wild card: Consider buying a used MX350 first. If your kid becomes obsessed (and they probably will), you can always upgrade later.
