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.

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 ControlThe 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 ClearanceThe 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 RequiredDue 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. Seen during our prototype testing here:
