What Is the Fastest Electric Dirt Bike? Top Speed Machines Ranked

If you’re hunting what is the fastest electric dirt bike, you’re probably picturing MX-level punch, long straights, and a GPS that keeps climbing. Today’s performance e-motos range from featherweight trail rockets to full-on motocross platforms—and the fastest of them can eclipse 100 mph in independent tests.

In this guide, we rank the fastest electric dirt bikes by claimed or verified top speed, highlight realistic numbers from reputable brand/retailer pages, and include a quick note on kids’ speeds so parents don’t accidentally shop a missile.

Two quick primers before we rank: (1) top speed depends on gearing, rider position, and surface; (2) a bike that’s “fastest” isn’t automatically best for you. For tight singletrack, controllability and weight matter more than peak mph. We’ll show you both the raw speed ladder and where each platform fits.

Sources include official brand pages and well-established retailers (e.g., Stark, Surron/Sur-Ron, Talaria, Cake, KTM, Electric Motion, Segway), plus reputable reviews that measured or documented speed. You’ll see those cited near each entry so you can sanity-check the numbers yourself. For younger riders, we’ll anchor typical 36V kids’ minis (~15–17 mph) with a representative link you can use once without over-branding.

Fastest Electric Dirt Bikes (2025): Top Speed Ranking

Ordered by credible claimed or independently verified top speed. Where brands don’t publish a figure, we cite respected testing or retail data.

1) Stark VARG (MX) — ~100+ mph (GPS-verified tests)

Stark’s flagship MX platform is the current top-speed king among production e-dirt machines. While Stark’s own product page focuses on power (up to 60 hp) rather than a printed mph number, independent testing has recorded GPS-verified 103–104 mph on the VARG, with the dash limited to ~88 mph. 

Why it’s fast: high power output, MX gearing, and aero at speed.
Good to know: built for track performance and price reflects that; not the ideal beginner pick.

2) Surron / Sur-Ron Storm Bee — ~68 mph (110 km/h)

The Storm Bee steps up from lightweight play bikes into full-size territory. Official spec pages cite ~68 mph top speed with a robust 104V battery and serious torque. Some U.S. retailers list comparable figures; off-road and road-legal trims exist. 

Why it’s fast: bigger voltage, mass, and aero stability vs. 60V class.
Trade-off: heavier than the featherweight category; more bike to muscle in tight woods.

3) CAKE Kalk platform — +90 km/h (~56 mph)

CAKE’s Kalk lineup posts “+90 km/h” (≈56 mph) on its official pages, with light weight and premium suspension. Street-legal and off-road variants exist; top-end depends on version and gearing. 

Why it’s fast: efficient chassis and gearing; strong power-to-weight feel.
Best for: riders balancing pace with design, refinement, and low noise.

4) KTM FREERIDE E (2025) — ~59 mph (95 km/h)

KTM’s latest FREERIDE E generation lists 95 km/h (≈59 mph) in official and press materials. Earlier model-year tests reported 50–55 mph depending on map and gearing; the 2025 refresh raised the ceiling with a new drivetrain.

Why it’s fast: full-size chassis and WP suspension deliver stability up top.
Bonus: wide dealer network and a platform many riders can demo locally.

5) Talaria Sting (MX family) — 47+ mph

Talaria’s U.S. page states “Top speed 47+ MPH” with ~43 miles @ 25 mph and ~58 kg weight. Higher-trim variants and gearing changes can nudge the number, but 47+ mph is the published baseline.

Why it’s fast for its size: strong 60V drive and well-sorted chassis.
Sweet spot: playful trail fun, approachable mass, upgrade ecosystem.

6) Sur-Ron Light Bee X — ~75 km/h (~46.6 mph)

Brand/retailer pages cite ~75 km/h top speed and ~57 kg curb weight for the current Light Bee X, with a 75 km cruising figure (conditions vary). It’s a benchmark in the lightweight class. 

Why it’s beloved: lively torque + very manageable weight.
Tip: gearing, tires, and rider weight move the needle on top speed.

7) Segway X260 — 46.6 mph

Segway’s own product materials specify 46.6 mph max speed and 74.6 miles max range (test conditions apply). It’s comparable to Light Bee X/Talaria Sting in envelope and feel. 

Why it’s a contender: familiar brand; swappable battery and big aftermarket.
Caveat: as with others in this class, control and range > bragging rights.

Honorable mentions: trials-style electrics

Electric Motion’s Epure Race lists ~43–43.5 mph depending on year; it’s built for precision, not top speed. If your riding is obstacles and balance over straights, trials bikes belong on your short list. 

Fastest Kids’ Electric Dirt Bikes (Reality Check)

For young riders, “fastest” should not be the goal. Mainstream kids’ 36V minis typically publish ~15–17 mph top speed with short ride times—perfect for supervised practice. (Example: Razor MX650 lists up to 17 mph with a 36V system.) If you need a live product anchor, use one representative link once and keep the copy brand-light: a 36V mini electric dirt bike for around-the-yard fun and mellow trails. 

Top Speed vs. Real-World Riding: What Actually Matters

• Gearing & terrain: Tall gearing raises top speed but can blunt hill punch; trail gearing does the opposite.
• Weight & handling: Sub-130 lb machines feel like big mountain bikes with throttles; heavier platforms are calmer at 60+ mph.
• Brakes & tires: Four-piston hydraulics and appropriate rubber increase confidence more than +2 mph.
• Range at a steady speed: When comparing, use cruise @ ~25 mph (brands publish this—e.g., ~43 miles for Sting; 75 km for Light Bee X). Aggressive pace and climbing cut those numbers fast. 
• Charging: Many lightweight platforms quote ~2–3 hours to full depending on charger; check if fast charging is supported and what it does to battery warranty.

Safety & Legality (Read Before You Rip)

Most electric dirt bikes (no pedals) are sold off-road only. Street operation usually requires a street-legal motorcycle (factory) or a conversion where your jurisdiction allows it—DOT lighting, mirrors, VIN/title, registration, insurance, and often a motorcycle endorsement. Quiet ≠ legal. Always check your state/region’s current rules and the product page (many clearly mark off-road only). 

Buying Tips (If Top Speed Is Your Priority)

• Be honest about terrain. If your rides are tight trees and rock gardens, a nimble 60V bike may deliver more joy than a 100 mph missile.
• Compare apples to apples. Look for brand/retailer specs: top speed, cruise range at ~25 mph, weight. (Sting/Light Bee X/Segway post transparent numbers.)
• Plan for brakes/tires. If you’re chasing top speed, budget for premium pads/rotors and road-appropriate rubber where allowed.
• Mind charging. Confirm time to 100% and whether a higher-output charger is available/supported.
• Test before you buy. Dealer networks (e.g., KTM) or multi-brand retailers can arrange demos; speeds feel different in the dirt than on paper.

Example Youth Option (use once to keep branding balanced)

For supervised learners, a 36V mini electric dirt bike (~15 mph, dual suspension, short charge time) keeps speeds appropriate while skills grow. (Link once: 36V mini electric dirt bike—colors vary.)

Conclusion 

So what’s the fastest electric dirt bike right now? For sheer top speed, the Stark VARG sits on the throne with GPS-verified 100+ mph in independent runs—well beyond what most riders need, and more than many venues allow. Just behind, Surron’s Storm Bee cracks the ~68 mph bracket, while CAKE’s Kalk, KTM’s FREERIDE E (2025), and the lightweight trio (Talaria Sting, Light Bee X, Segway X260) occupy the 46–59 mph band depending on gearing and trim. 

But top speed is only one metric. If you ride tight singletrack, a lighter 60V platform with strong brakes, good tires, and quick charging is often the best choice for actual fun. If you track-ride or crave maximum straight-line pace, premium MX platforms justify their cost. For kids, stick to 36V minis around 15–17 mph and keep it supervised. Either way, compare weight, range at ~25 mph, charge time, and parts support before you buy—and always check where you can legally ride. That’s how you pick a fast bike you’ll still love in six months.
