The Gates PowerGrip GT4 20mm Primary Belt is a direct OEM-width replacement and performance upgrade for the E Ride Pro SR and Pro-SS 3.0 electric dirt bikes. Designed specifically for the wider factory belt pulley system used on E Ride Pro platforms, this belt delivers higher torque capacity, improved tracking, and longer service life for riders putting real miles on their e-moto, on trails, tracks, and street riding. Unlike narrower belts commonly used on Sur Ron LBX, E Ride 2.0, or Talaria XXX, the E Ride Pro 3.0/SR uses wider flanged belt sprockets, allowing a 20mm belt to properly distribute load, maintain tracking, and handle higher torque without edge wear or heat buildup. The Gates PowerGrip GT4 20mm belt uses a high-torque synchronous construction with an advanced GT4 tooth profile designed to run true on flanged pulleys. When paired with the correct pulley setup, it offers improved durability, smoother power transfer, and longer service life, especially on modified or hard-ridden bikes. Whether you’re replacing a worn belt or upgrading proactively, this is the correct belt for riders who want reliability from their E Ride Pro drivetrain.
