Ultra Bee Primary Belt
Stock replacement Continental HTD 640 8M 25 CXA primary drive belt for Ultra Bee.
The PowerGrip™ GT4™ features a robust high-torque synchronous design and optimized tooth shape to maintain proper clearance to the flanged pulleys found on Sur Ron and Segway e-bikes. No other belt on the market is engineered so precisely for our specific e-bikes.
Replacing your stock belt with a Gates® PowerGrip™ GT4™ after it breaks – or better yet, before it breaks – is one of the best investments you can make in your bike, bar none.
This is a direct replacement for your Ultra Bee to get you back on the Trails shredding for days. These belts are long-lasting upgrades capable of high-power builds.
