EBMX Extended Swing Arm: Sur-Ron Light Bee, E Ride Pro

Significantly increase the size and strength of your Sur-Ron Light Bee S/X or E Ride Pro S/SS 2.0 with the EBMX Extended Swing Arm upgrade. The EBMX Swing Arm extends your wheelbase by over 2" and increases your rear wheel travel by 3/4". This makes your bike more stable and planted, while keeping the front wheel down during hard acceleration.

Features & Specs

• Massive strength upgrade over OEM swing arm
• 60mm (+2.4") Longer Wheelbase
• 220mm (+3/4") suspension travel (with EBMX YSS shock and linkage)
• Stronger and more rigid for less flex
• Support for wider tires
• Dirt-shedding design improves reliability
• Extended 60mm for better high-speed stability and cornering

Rear Shock Upgrade Recommended:  An extended swing arm upgrade increases the force added your rear shock and must be paired to a high-quality shock with a higher spring rate for best performance. OEM style shocks will not perform well with this swing arm.

Compatibility

• E-Moto Compatibility: Sur-Ron Light Bee, Segway X160/X260, E Ride Pro S/SS 2.0
• Compatible with stock sprockets and 54T-58T, and 64T rear sprockets
• Works with most upgraded suspension systems and rear wheels
• Supports larger sprocket setups with integrated chain guide (available separately)

Additional Features

• Reinforced CNC-Machined Design Built from aerospace-grade billet aluminium, this new swing arm boasts a dirt-shedding geometry and robust construction. The fully CNC-machined structure ensures tighter tolerances, greater durability, and a finish that speaks to both performance and premium craftsmanship.
• Extended Length for Stability & Control The extended geometry improves rear wheel traction and stability—especially valuable in high-power, off-road conditions. This means better control, smoother landings, and improved handling under acceleration.
• New Chain Guide System (sold separately) A complete new chain guide system now supports 54T-58T, and 64T sprockets, catering to torque-focused setups for trail, climb, or stunt applications. This system helps keep your chain in line, even under extreme conditions
• Improved Mud & Debris Clearance The new swingarm features precision-cut channels that actively shed dirt and debris, reducing buildup and minimizing maintenance. Ideal for riders who don't shy away from tough trails and muddy terrains.
• Aftermarket Ready – Chain Replacement Required Due to the extended design, your existing chain will be too short. A new chain is required and should be sized appropriately for your sprocket selection and tension preferences.
