Modify the shape of your bike with the EV Freaks swing arm extension. This aircraft-grade aluminum extender moves the rear wheel back 50mm to create more space and stability. These Sur-Ron accessories also allow you to install larger tires on the Light Bee X. Like all of our Sur-Ron upgrades, we have designed and tested these parts for performance. By extending the rear wheel backwards, you’ll be able to climb large hills and increase acceleration from the beginning, but you will also lose some maneuverability. For this reason, we don’t recommend these Sur-Ron parts for extreme off-road use.
