Square-shape connectors are also included for separate motor use, though they carry a slightly higher risk of water ingress due to partial PVC coverage.<\/p>\n<h4>Sensing Method<\/h4>\n<p>Two sensor types are commonly used: Hall sensors and encoders. Hall sensors offer wide compatibility but slower response under high-speed or traction-loss conditions. Encoders, used in VTB motors, provide premium speed feedback, throttle sensitivity, and precise control, ideal for riders performing wheelies or demanding high control accuracy.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Surron Ultra Bee The VTB Beast motor is designed to maximize the power of your Surron Ultra Bee.
