Looking to significantly increase the size and strength of your SurRon Light Bee or E-Ride Pro SS 2.0? The EBMX Extended Swingarm increases your wheelbase by 60mm (2.4") and boosts rear wheel travel by 3/4", giving your bike improved high-speed stability and more controlled power delivery. It reduces front wheel lift under hard acceleration and provides a more planted ride feel—especially when paired with a high-performance rear shock.
+60mm (2.4") Longer Wheelbase
+220mm (3/4") Rear Suspension Travel (when used with EBMX YSS shock and linkage)
Massive Strength Upgrade Over OEM Swingarm
Supports Wider Tires and Larger Sprockets
Designed for Extreme Off-Road Use, Stunts, and Racing
Important Fitment Note:
Due to the added leverage on the shock, this swingarm is highly recommended to be used with the EBMX YSS rear shock and linkage. A longer swingarm increases the forces transferred into the shock, and OEM-style shocks will not perform well under these added loads. Use of a higher-rate spring and high-quality shock is required for best results.

Key Features
-
CNC-Machined Billet Aluminum Construction
Fully CNC-machined from aerospace-grade billet aluminum, the EBMX swingarm offers a substantial rigidity and strength upgrade over the stock unit. Built to withstand the abuse of hard enduro, track riding, and freestyle use.
-
Extended Geometry for Stability and Traction
The +60mm extended length improves cornering confidence and reduces rear wheel lift during jumps or under throttle-heavy acceleration. Ideal for torque-heavy motor setups or high-speed terrain.
-
New Chain Guide System (sold separately)
The updated geometry includes mounting support for a new EBMX chain guide designed to handle 54T–58T and 64T sprockets. Whether you’re running a torque-focused gearing setup or a high-speed sprocket, this guide keeps your chain tracking straight under extreme load.
-
Mud and Debris Clearance Built In
Precision-cut dirt-shedding channels help reduce buildup in wet and muddy conditions. Maintenance is easier, and long-term performance is improved.
-
Aftermarket-Ready (Chain Required)
Because of the longer wheelbase, your OEM chain will be too short. A longer chain is required and should be sized appropriately for your gearing and wheel position.
