Gates GT4 Primary Belt

Upgrade your drivetrain with the Gates PowerGrip™ GT4™ Primary Belt—engineered for serious riders who demand durability, precision, and performance.

Built with a high-torque synchronous design and optimized tooth profile, the GT4 belt maintains perfect alignment with flanged pulleys found on Sur-Ron and Segway e-bikes. This results in smoother power delivery, reduced wear, and longer belt life compared to stock options.

Whether you're replacing a worn belt or upgrading before failure, this is one of the smartest reliability mods you can make.
