The optimal primary belt width for Surron and Segway e-bikes has been hotly debated, with many shops arguing that the widest possible belt (17mm) will deliver the best durability. Gates® revealed that 16mm is the optimal belt size for these bikes. Larger belts show a tendency to push to the extreme edge of the flanged pulleys due to the slight misalignment of the motor and jackshaft from the factory, causing accelerated wear and premature belt failure. The PowerGrip™ GT4™ features a robust high-torque synchronous design and optimized tooth shape to maintain proper clearance to the flanged pulleys found on Surron and Segway e-bikes.
