Power that feels natural. The SPECTER-ST 2.0 couples Bafang’s flagship M620 1000W mid-drive (up to 160 N·m) with a responsive torque sensor for seamless, intuitive assist. A long-range 48V 17.5Ah main battery comes standard—add an optional 15Ah or 17Ah second pack for big-day adventures up to ~80 miles. Full suspension, 4-piston hydraulic brakes, and grippy 27.5×3.0" tires keep you confident on pavement, gravel, and singletrack.
