EBMX Extended Swingarm

EBMX Extended Swingarm

Looking to significantly increase the size and strength of your SurRon or E Ride Pro? The EBMX swingarm will extend your wheelbase by over 2" and increase your rear wheel travel by 3/4".  This will make your Surron or E-Ride more stable and planted and reduce the front wheel from coming up during hard acceleration.

• 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 

Highly recommended to pair this with the EBMX YSS rear shock and linkage for the increased loads on your rear shock with this extended swingarm.  A longer swingarm increases the forces into your rear shock and must be matched to a high quality shock with a higher spring rate.  OEM style shocks will not perform well with this upgrade.

Key Features

• Reinforced CNC-Machined Design
  Built from aerospace-grade billet aluminium, this new swingarm 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 and 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 minimising 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.
