TL;DR: Which Razor Electric Dirt Bike Should You Buy?
Looking for the straight answer? The Razor MX350 and SX350 are practically twins separated at birth – same guts, same performance, different outfit. The SX350 rocks Jeremy McGrath’s signature graphics and costs a bit more for the privilege. Your wallet and your kid’s style preference will make this decision for you.

Deep Dive: What Parents Actually Want to Know
Speed & Safety: 14 MPH Sweet Spot
Both bikes max out at 14 mph – fast enough to feel like flying, slow enough that you won’t need therapy. This speed hits the perfect balance for teens learning to ride without giving parents premature gray hair.
Pro Tip: That single-speed throttle acts like an on/off switch. It’s not gradual acceleration – it’s “hold on or eat dirt.” Your teen will love it; you might need a stiff drink the first few rides.
Battery Life Reality Check
30 minutes of continuous runtime sounds short until you realize most kids need a break after 20 minutes of bouncing around on a bike with zero suspension. It’s actually perfectly timed for attention spans and avoiding overexertion.
Charging Time: Plan for 8-12 hours between rides. Perfect overnight charging routine.
The Suspension Situation (Or Lack Thereof)
Neither bike has suspension, which means:
- The Good: Less maintenance, fewer parts to break
- The Reality: Your kid’s spine becomes the suspension system
- The Solution: Those chunky off-road tires help absorb some impact
Translation: Great for smooth dirt paths, less ideal for motocross track dreams.
Braking: Rear-Only Reality
Both bikes feature rear brake only via hand lever. For a 140-lb max weight bike hitting 14 mph, it’s adequate but requires:
- Proper technique training (no front brake to rely on)
- Understanding of longer stopping distances
- Extra caution on steep descents
Who Should Buy Which Bike?

Choose the MX350 If:
- You’re budget-conscious but want quality
- Your kid prefers classic, understated style
- You’re buying for general recreational riding
- You want the most bang for your buck

Choose the SX350 If:
- Your kid is obsessed with motocross culture
- The Jeremy McGrath connection matters
- Style and graphics are important factors
- Budget isn’t the primary concern
The Honest Parent Review
What We Love:
- Chain-driven system (not cheap belt drive)
- Pneumatic tires for better traction
- Solid build quality from Razor
- Perfect starter bike power level
- Easy to maintain and repair
What Could Be Better:
- That on/off throttle takes getting used to
- Zero suspension means bumpy rides
- 30-minute runtime feels short on good days
- No front brake requires riding adjustment
Frequently Asked Questions
Q: Can adults ride these bikes? A: If you’re under 140 lbs and don’t mind looking like you borrowed your kid’s bike, sure. But you might want to consider the adult-sized options instead.
Q: Are replacement parts available? A: Yes, Razor has excellent parts availability. These aren’t disposable toys – they’re built to be maintained.
Q: How long do these bikes typically last? A: With proper care, expect 2-3 years of regular use before major maintenance needs kick in.
Q: Is the SX350 worth the extra money? A: Only if the McGrath graphics and styling matter to you or your rider. Performance-wise, you’re paying for looks.
The Final Verdict: MX350 or SX350?
Here’s the deal: both bikes will put the same smile on your kid’s face. The MX350 gives you identical performance for less money. The SX350 gives you motocross street cred with Jeremy McGrath’s blessing.
Our Pick: For most families, the MX350 offers the better value proposition. Save the extra cash for safety gear, which you’ll definitely need more than fancy graphics.
However: If your teen is motocross-obsessed and the McGrath connection will make their year, the SX350’s premium is worth it for the happiness factor alone.
Ready to Pull the Trigger?
Both the Razor MX350 and SX350 represent solid entry points into electric dirt biking. They’re not perfect – that missing suspension and abrupt throttle will remind you this isn’t a premium bike – but they’re reliable, fun, and built by a company that knows electric ride-ons.
Bottom Line: You can’t go wrong with either choice. Your biggest decision isn’t which bike to buy – it’s how much you’re willing to spend on the inevitable gear upgrades your new dirt bike rider will want next.
