If you own a Surron Light Bee, you already know it’s one of the most thrilling electric dirt bikes on the market. But if you’re tall, ride aggressively, or crave more suspension travel and stability—especially off-road—you’ve probably hit the limits of its stock geometry.
Enter the EBMX V2 Extended Swing Arm—a game-changing upgrade that doesn’t just tweak your ride… it redefines it.
After months of real-world testing, bolt-snapping mishaps, muddy trails, and high-speed cornering, I’m here to tell you: this swing arm is worth every penny. And in this deep-dive review, I’ll explain exactly why—backed by facts, firsthand experience, and a few hard-earned lessons.
Why an Extended Swing Arm? The Physics Behind the Upgrade
Before we geek out over bolts and honeycomb designs, let’s talk why you’d even consider an extended swing arm for your Surron Light Bee.
1. Increased Rear Suspension Travel
The stock Surron Light Bee comes with approximately 200mm (8 inches) of rear suspension travel. That’s decent—but not enough if you’re pushing hard on rough terrain or pairing it with a high-travel fork (like the popular 230mm Enduro forks).
The EBMX V2 Extended Swing Arm increases your effective rear travel to over 230mm (9+ inches)—thanks to a longer leverage ratio.
How it works: A longer swing arm means the rear shock moves through a greater arc for the same wheel displacement. This translates to smoother bump absorption, reduced bottoming out, and a noticeably plusher ride—especially at speed.
Riders who’ve tested both setups consistently report: “Your bike feels like it has a completely different rear end.”
2. Improved High-Speed Stability & Cornering
Many fear that lengthening the wheelbase will make the bike sluggish. But in practice? The opposite happens.
With the extended swing arm:
- The rear wheel tracks more predictably through corners.
- You gain confidence to lean harder without the back end “tucking” or sliding unpredictably.
- The bike feels planted, not sluggish—ideal for berms, loose gravel, or forest trails.
As one rider put it: “It’s like the rear finally trusts the front.”
The Problem with Gen 1: Bolt Failures & Play
EBMX isn’t new to the extended swing arm game. Their first-generation model was revolutionary—but flawed.
The Fatal Flaw: A Proprietary Bolt That Kept Breaking
The original design used a custom, ultra-long bolt to connect the linkage to the swing arm. Sounds fine—until you ride aggressively.
“I sheared that bolt twice,” says our tester (6’3”, running 18”/21” wheels). “Even with fresh linkages, there was always play—a ‘dink-dink-dink’ sound every time I hit a bump. Eventually, the vibration fatigued the bolt until it snapped.”
Worse? Replacing it meant sourcing a rare bolt or risking damage to the swing arm threads. One rider even had to sacrifice multiple linkages just to keep riding.
Enter the EBMX V2: A Complete Redesign That Fixes Everything
The Version 2 Extended Swing Arm isn’t just an update—it’s a total rethink. And it solves every major complaint from Gen 1.
✅ 1. Traditional Bolt Design = Zero Play
Gone is the fragile proprietary bolt. The V2 now uses a standard shanked bolt—the same type used in OEM Surron linkages.
- Shanked section = precise fit through the linkage bushing.
- No threads in the shear zone = dramatically reduced stress.
- Result: Absolutely zero slop. Lift the rear wheel—no wobble, no clunking. Just rock-solid suspension action.
“Now my suspension feels tighter, smoother, and more responsive. It’s like night and day.”
✅ 2. Modular Design = Future-Proof Investment
One of the smartest upgrades? Interchangeable center inserts.
- Buy it for your Surron Light Bee today.
- Switch to an E-Ride Pro or Talaria Sting tomorrow? Just swap the center section.
- Same swing arm, new mounting width, same performance.
This modularity makes the V2 a long-term investment, not a one-bike part.
✅ 3. Cleaner, Smarter Aesthetics
The V2 features a honeycomb-textured outer shell—not just for looks, but function.
- Flat inner cavity = easier to clean (no mud traps).
- Textured exterior = hides dirt, grime, and minor scuffs.
- Compare that to the Gen 1, which collected chain lube, mud, and grit like a magnet.
Even after weeks of muddy rides, the V2 stays surprisingly clean.
✅ 4. Better Hose & Fender Integration
- Brake hose mounts are now recessed, preventing rub-through (a common issue on Gen 1 that wore off powder coat in weeks).
- Rear fender compatibility: While the stock Surron fender doesn’t fit perfectly, a quick Dremel cut solves it—and now your shock stays protected from mud and debris.
Real-World Performance: What Riders Actually Experience
Let’s cut through the specs and talk feel.
🌲 Off-Road Confidence
With 230mm+ of rear travel and a balanced front/rear setup (especially when paired with a long-travel fork), the bike absorbs square-edged hits that would previously jolt your spine.
- Rock gardens? Smooth.
- Root sections? Controlled.
- Big landings? No bottoming.
🏁 Cornering Like a Pro
The extended wheelbase doesn’t kill agility—it enhances control.
“I can lean the bike way further than before, and the rear just hooks. It doesn’t wash out or feel nervous. It’s like the chassis finally matured.”
This is huge for taller riders (6’+), who often feel cramped or unstable on the stock Light Bee.
⚙️ Durability You Can Trust
After months of abuse—including jumps, hard landings, and muddy endurance rides—the V2 shows zero signs of fatigue. No creaks, no cracks, no bolt failures.
EBMX clearly listened to early adopters and engineered a robust, race-ready solution.
Who Should Buy the EBMX V2 Extended Swing Arm?
This isn’t for everyone—but if you match any of these, it’s a must-have:
- You’re over 6 feet tall and feel cramped on the stock bike.
- You run large wheels (18”/21” or 19”/18” setups).
- You’ve upgraded your fork to 200mm+ travel and want rear balance.
- You ride aggressively off-road—trails, hills, jumps.
- You’ve experienced linkage slop or bolt failure with other extended arms.
- You want a future-proof part that works across Surron/E-Ride platforms.
💡 Pro Tip: Pair the V2 swing arm with a high-quality rear shock (like the EBMX Pro Shock or Ohlins) to fully unlock its potential.
Installation & Compatibility Notes
- Fits: Surron Light Bee S/X, E-Ride Pro (with correct center insert).
- Wheels: Works with 16”–21” rear wheels (plenty of axle slot adjustment).
- Chainline: Ample room for large chainrings (up to 58T+).
- Tools Needed: Standard bike tools + torque wrench (critical for linkage bolts).
- Time: 2–3 hours for first-time install (including shock re-valving if needed).
⚠️ Warning: Do not reuse old linkage bolts. Always use fresh, high-grade hardware.
Price vs. Value: Is It Worth $500?
At ~$500 USD, the EBMX V2 isn’t cheap. But consider:
- Stock swing arm: $0, but limited travel, cramped for tall riders.
- Gen 1 extended arm: ~$450, but plagued by reliability issues.
- V2 Extended Arm: $500, but solves all flaws, adds travel, improves handling, and lasts.
When you factor in reduced maintenance, enhanced safety, and pure riding joy, it’s a high-value upgrade—especially for serious riders.
Think of it like upgrading from economy to business class: once you experience it, you can’t go back.
