BH51M NSO Key Features Sound by JBL and Bluetooth Calls The current BH51M NSO product record explicitly lists Sound by JBL, open-ear speakers and a wind-proof microphone. It supports music and phone calls through Bluetooth, and the remote can activate the connected phone’s voice assistant service. This page uses the verified JBL and audio configuration without adding an unsupported performance ranking. Smart Lighting, Turn Signals and Brake Warning The product information lists front and rear lighting, 53 built-in LED lights, automatic sensor lighting, turn signal indicators and brake warning lights. The handlebar-mounted remote controls turn signals and related hands-free functions. The current description states that significant deceleration activates the brake warning lights for 8 seconds. Fall Detection and SOS The current Product data lists patented fall detection and SOS Alert. It describes an SMS alert with GPS location to preset emergency contacts after 90 seconds. Connected phone, App and configured emergency contacts are required, so this is not an independent emergency service.
