The Gates PowerGrip GT4 16mm primary belt is the undisputed best belt for Sur Ron and Segway e-bikes, developed jointly by GritShift R&D and Gates engineers. Research confirmed that 16mm is the optimal width 17mm belts track to the extreme edge of flanged pulleys due to factory motor/jackshaft misalignment, causing accelerated wear and premature failure. The GT4's optimized tooth shape maintains proper clearance to the flanged pulleys found on these specific bikes. No other belt on the market is engineered this precisely for this application.
Fitment:
High-torque synchronous design with ethylene elastomer construction for enhanced durability. Tested on 96V systems and high power output applications. Manufactured in the USA. Part Number: 560-8MGT-85. Make belt changes even easier with the GritShift Multi Tool.
