What bikes does the Gates GT4 560-8MGT-20MM belt fit?
- E Ride Pro-SR
- E Ride Pro-SS 3.0
- E Ride Pro-SS 4.0
Why do the E Ride Pro-SS 3.0 and Pro-SR take a 20 mm belt?
Because their belt sprockets are wider. Unlike the narrower belts used on the Sur Ron Light Bee X, E Ride Pro-SS 2.0 or Talaria XXX, the E Ride Pro-SS 3.0 and Pro-SR use wider flanged belt sprockets, and a 20 mm belt is what lets those sprockets distribute load properly, maintain tracking and handle higher torque without edge wear or heat buildup. Fitting the narrower Gates GT4 Power Grip Belt 560-8MGT-16MM we sell for the Light Bee and Pro-SS 2.0 gives up that width, so match the belt to the platform.
Is the 20 mm GT4 belt right for a modified E Ride Pro?
Yes, GritShift rates it for stock and high-output modified builds. The high-torque synchronous construction and the GT4 tooth profile run true on the flanged pulleys, and the ethylene elastomer compound resists stretch and wear, which is why we call it the correct belt for riders who want reliability from the E Ride Pro drivetrain, whether they are replacing a worn belt or upgrading proactively before one fails.
Who makes the 560-8MGT-20MM belt?
Gates. The application came out of GritShift R&D testing alongside Gates engineers, and Gates manufactures the belt in the USA. It is a PowerGrip GT4 belt in the 560-8MGT-20MM size, and the E Ride Pro-SR, Pro-SS 3.0 and Pro-SS 4.0 are the only bikes on its fitment line.
